Quite a few of the defconfigs have not been updated for quite some time
and are beginning to be a bit useless.  Also since we switched to RTC_LIB
quite a few systems no longer read their RTCs on bootup so their
defconfigs should be updated to enable RTC_CLASS and CONFIG_RTC_HCTOSYS.
A hand full of systems is still using read_persistent_clock() to read
the RTC on bootup.  The use of this function should preferably be replaced
by RTC_CLASS and CONFIG_RTC_HCTOSYS.

Can we use RTC_CLASS option directly to replace RTC_LIB on the file,
arch/mips/Kconfig by default? If so all deconfigs may not be modified.

RTC_CLASS implies RTC_LIB.  It's not a replacement.

The previous patch set was Signed-off-by: Andrew Morton and added to
the -mm tree, however comments from Shinya Kuribayashi prompted me to
make some improvements.

The first three patches are unchanged from the previous set (I hope it
is not a breach of etiquette to include them again).  The forth which
allows uart bug types to be statically specified is completely
removed.  And the fifth (now forth) is simplified and now only adds a
uart type for the OCTEON uart.

And as I previously said:
Since these are the only non-mips specific patches required for OCTEON
cpu support, it is necessary to get these Signed-off-by before the
full OCTEON patch set can proceed.


Four patches to follow.

Thanks,

David Daney (4):
   8250: Don't clobber spinlocks.
   8250: Serial driver changes to support future Cavium OCTEON serial
     patches.
   Serial: Allow port type to be specified when calling
     serial8250_register_port.
   Serial: UART driver changes for Cavium OCTEON.

In serial8250_isa_init_ports(), the port's lock is initialized.  We
should not overwrite it.  In early_serial_setup(), only copy in the
fields we need.  Since the early console code only uses a subset of
the fields, these are sufficient.

In order to use Cavium OCTEON specific serial i/o drivers, we first
patch the 8250 driver to use replaceable I/O functions.  Compatible
I/O functions are added for existing iotypeS.

An added benefit of this change is that it makes it easy to factor
some of the existing special cases out to board/SOC specific support
code.

The alternative is to load up 8250.c with a bunch of OCTEON specific
iotype code and bug work-arounds.

Add flag value UPF_FIXED_TYPE which specifies that the UART type is
known and should not be probed.  For this case the UARTs properties
are just copied out of the uart_config entry.

This allows us to keep SOC specific 8250 probe code out of 8250.c.  In
this case we know the serial hardware will not be changing as it is on
the same silicon as the CPU, and we can specify it with certainty in
the board/cpu setup code.

The alternative is to load up 8250.c with a bunch of OCTEON specific
special cases in the probing code.

I meas if we use directly RTC_CLASS on the file, arch/mips/Kconfig, as the
following:
==
config MIPS
        bool
        default y
        select HAVE_IDE
        select HAVE_OPROFILE
        select HAVE_ARCH_KGDB
        # Horrible source of confusion.  Die, die, die ...
        select EMBEDDED
        select RTC_LIB --> RTC_CLASS
===

If so RTC_Class and RTC_HCTOSYS options will be enabled for all platforms by
default as you expect. I think it will be given a hint for the developers that
they should develop their RTC towards supporting RTC_CLASS in the future, not
other choices. And it may be helpful to have an unified RTC mode quickly.

Thanks & Best Regards

Great! and makes sense.  Thank you for taking care of my comments.  I've
also checked the serial patches of version 2, and they looks in good
shape.

You seem to drop the assignment of port.ops ?

Hi Phil,

It turns out that I have to pass parameters to the linux kernel. I
have to do the jump as following:

        entryPoint = (void *) 0x8036a000;
        entryPoint(2, args, NULL);

If I am using entryPoint(), there will be exception in the early stage
of linux kernel. I still don't understand why this works. When I use
BDM to jump to 0x8036a000, there is no parameter passed in.

Thanks,

Mike

The port.ops are initialized in the preceding call to 
serial8250_isa_init_ports(), we don't have to set it again as we are no 
longer clobbering it with a full structure assignment.

Perhaps the patch commentary should be adjusted to mention this.

Hello James,

Any news about this one? I think this patch should go via linux-scsi,
unless you would be insisting on pushing it via linux-mips, in which case
I'll politely bug Ralf about it. :)

Thanks,
Dmitri

Looks OK for the local change.

Globally, having driver->remove and platform_driver->remove return int
instead of void looks wrong.  Particularly when the only use cases are
in drivers/base/ and they all ignore the return code.

Greg and Kay ... shouldn't we simply redefine the return values for the
remove methods in these structures to return void (and thus match the
use case)?

James

Aren't there many many drivers across the tree, using the "int remove" version?

Yes ... since it's a function prototype.

However, if drivers/base simply discards the return, it's a trap we
shouldn't be setting.

Hmmm, it does look like the return value is discarded, please see
drivers/base/dd.c::__device_release_driver() for details.

Does this not deserve a good cleanup?

Sure, it might be. If you want to patch hundreds of files, send
patches to maintainers, patch drivers you can not even compile, we
could do that.

We are already in the middle of a ~400 files "struct device" bus_id
conversion, and only very few maintainers respond to these patches. We
also never got any reply to the SCSI bus_id patch we sent weeks ago.
:)

Even when it's "a good cleanup", with maintainers not responding, and
supporting it, it's a real pain to change things like this. But, if
you want to go ahead and do that, let us know.

Hmm, OK ... if you want a review, over the SCSI list is best.

Things like this:

Give cause for concern:  in the original, we know we scribble over 20
bytes of user space.  With the new one we scribble over an unknown
number (which could potentially be much greater than 20).  That's an
accident waiting to happen in userspace.

Yeah, but the name will have no real limit. What should we do here?
Just Truncate at 20, because we "know" it's not longer?

Well, the problem is the stupid ioctl which gives nowhere to say how
many bytes the buffer is.  For safety's sake, yes, I think you have to
limit it to 20 bytes.  Otherwise, on the day we introduce long names
some random application using this ioctl will die with data corruption
and that will be extremely hard to debug.

Do you want to take over the patch to the scsi tree, and we will work
from there. It's through Greg's tree in -next since a while.

This patch set introduces preliminary support for Cavium Networks'
OCTEON processor family.  More (but not detailed) information about
these processors may be obtained here:

http://www.caviumnetworks.com/OCTEON_MIPS64.html

These patches depend on the '[PATCH 0/4] serial: Patches for OCTEON
CPU support (version 2).' set that Alan Cox already has queued up.
They can be seen here:

http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=4934774E.6080805%40caviumnetworks.com

This initial patch set adds support for booting an initramfs to a
serial console.  Follow-on patch sets will add support for the on-chip
Compact Flash, ethernet, USB, PCI, PCIe, I2c and other peripherals.

With this fifth revision of the patches I think we have address all
the issues explicitly flagged as objectionable in the preceding
revisions.  The major change is reformatting of code and comments in
the first two patches of the set.  The only remaining checkpatch.pl
errors are due to that program's inability to handle MIPS assembly
language and inline asms.  Quite a bit of unused code was also
removed.

21 patches to follow as replies.

These are the rest of the new files needed to add OCTEON processor
support to the Linux kernel.  Other than Makefile and Kconfig which
should be obvious, we have:

dma-octeon.c    -- Helper functions for mapping DMA memory.
flash_setup.c   -- Register on-board flash with the MTD subsystem.
octeon-irq.c    -- OCTEON interrupt controller managment.
octeon-memcpy.S -- Optimized memcpy() implementation.
serial.c        -- Register 8250 platform driver and early console.
setup.c         -- Early architecture initialization.
smp.c           -- OCTEON SMP support.
octeon_switch.S -- Scheduler context switch for OCTEON.
c-octeon.c      -- OCTEON cache controller support.
cex-oct.S       -- OCTEON cache exception handler.

asm/mach-cavium-octeon/*.h -- Architecture include files.

+ * Spec
+ *
+ * memcpy copies len bytes from src to dst and sets v0 to dst.
+ * It assumes that
+ *   - src and dst don't overlap
+ *   - src is readable
+ *   - dst is writable
+ * memcpy uses the standard calling convention
+ *
+ * __copy_user copies up to len bytes from src to dst and sets a2 (len) to
+ * the number of uncopied bytes due to an exception caused by a read or write.
+ * __copy_user assumes that src and dst don't overlap, and that the call is
+ * implementing one of the following:
+ *   copy_to_user
+ *     - src is readable  (no exceptions when reading src)
+ *   copy_from_user
+ *     - dst is writable  (no exceptions when writing dst)
+ * __copy_user uses a non-standard calling convention; see
+ * arch/mips/include/asm/uaccess.h
+ *
+ * When an exception happens on a load, the handler must
+ # ensure that all of the destination buffer is overwritten to prevent
+ * leaking information to user mode programs.
+ */
+
+/*
+ * Implementation
+ */
+
+/*
+ * The exception handler for loads requires that:
+ *  1- AT contain the address of the byte just past the end of the source
+ *     of the copy,
+ *  2- src_entry <= src < AT, and
+ *  3- (dst - src) == (dst_entry - src_entry),
+ * The _entry suffix denotes values when __copy_user was called.
+ *
+ * (1) is set up up by uaccess.h and maintained by not writing AT in copy_user
+ * (2) is met by incrementing src by the number of bytes copied
+ * (3) is met by not doing loads between a pair of increments of dst and src
+ *
+ * The exception handlers for stores adjust len (if necessary) and return.
+ * These handlers do not need to overwrite any data.
+ *
+ * For __rmemcpy and memmove an exception is always a kernel bug, therefore
+ * they're not protected.

These files are used to coordinate resource sharing between all of
the programs running on the OCTEON SOC.  The OCTEON processor has many
CPU cores (current parts have up to 16, but more are possible).  It
also has a variety of on-chip hardware blocks for things like network
acceleration, encryption and RAID.

One typical configuration is to run Linux on several of the CPU cores,
and other dedicated applications on the other cores.

Resource allocation between the various programs running on the system
(Linux kernel and other dedicated applications) needs to be
coordinated.  The code we use to do this we call the 'executive'.  All
of this resource allocation and sharing code is gathered together in
the executive directory.

Included in the patch set are the following files:

cvmx-bootmem.c and cvmx-sysinfo.c -- Coordinate memory allocation.
All memory used by the Linux kernel is obtained here at boot time.

cvmx-l2c.c -- Coordinates operations on the shared level 2 cache.

octeon-model.c  -- Probes chip capabilities and version.

The corresponding headers are in asm/octeon.

Here we define the addresses and bit-fields of the Configuration and
Status Registers (CSRs) for some of the hardware functional units on
the OCTEON SOC.

Definitions are needed for:

CIU  -- Central Interrupt Unit.
GPIO -- General Purpose Input Output.
IOB  -- Input / Output {Busing,Bridge}.
IPD  -- Input Packet Data unit.
L2C  -- Level-2 Cache controller.
L2D  -- Level-2 Data cache.
L2T  -- Level-2 cache Tag.
LED  -- Light Emitting Diode controller.
MIO  -- Miscellaneous Input / Output.
POW  -- Packet Order / Work unit.

Gas from binutils 2.19 fails to compile some cop1 instructions with
-march=octeon.  Since the cop1 instructions are present in mips1, use
that arch instead.  This will be fixed in binutils 2.20.

Cavium OCTEON CPU support, requires a couple of additional hooks in
dem-default.c

Other than add a dev parameter to plat_unmap_dma_mem(), and hooks for
plat_dma_supported() and plat_extra_sync_for_device() which should be
nop changes for all existing targets, the only real change is to call
plat_unmap_dma_mem() from dma_free_{,non}coherent().  This is a nop
for all targets except jazz, and I expect that it is needed there.
Really if you map the memory in dma_alloc*, you should unmap it in
dma_free*.

Hi, all,

I have tried xorg-server-1.5.2 on loongson 2f recently.
But I found it doesn't work.
It's mainly because of this change:
http://www.x.org/wiki/PciReworkProposal

In short:
"Rather than duplicating the efforts of kernel developers, X.org needs to use the
interfaces provided by the kernel as much as possible."

I have read some code of libpciaccess, the new library utilizing kernel function
to access pci bus. It will try to mmap this file:
/sys/bus/pci/devices/0000:0x:xx.x/resource0
(replace x with any digit appropriate)
Note there is a 0 at the end of the file name. This file's permission is 600.

However, I found on my loongson system, there is only 
/sys/bus/pci/devices/0000:0x:xx.x/resource
Note there is no 0 at the end.

Then I tried to read kernel code. I found it seems that for mips linux to have
this file, HAVE_PCI_MMAP must be defined. However, it is currently not defined.

Since I am not familiar with PCI, yet.
So could someone please shed some light on this?
Why HAVE_PCI_MMAP is not defined?

Thanks in advance!

Zhang, Le

Yeah, but I'm still on the mailing list, so I saw it.  I don't "own" 
that particular module,
but for whatever it's worth, I'm OK with fixing the comment - though I'm 
surprised
that checkpatch let a non-canonical multi-line comment block like that 
go by.  ;o)

          Regards,

HAVE_PCI_MMAP must be defined when you have a pci_mmap_page_range()
function (see Documentation/filesystems/sysfs-pci.txt) and we don't have
a pci_mmap_page_range() on mips.

Hope that helps you.

Correct - but if the code is not present the kernel does not use an
alternative implementation.  I just looked into implementing that and it
seems nothing that I could do quickly to still get it into 2.6.28, sorry ...

Hi Ralf,

Any news about this patch and the next one? I just checked, it still
applies and builds beautifully :)

Thanks,

Yep. By default the get_maintainers.pl script which I used trawls through
'git log' to find everybody who was involved in a commit in each affected
file during the last 12 months. Kevin signed off commit b618336aac14 from
his old address.

As part of our efforts to get the Cavium OCTEON processor support
merged (see: http://marc.info/?l=linux-mips&m=122834773330212), we
have this CF driver for your consideration.

This version is split into two separate patches.  The first adds
some entries to the ata_timing table in libata-core.  The second is
the driver proper.

I will reply with the two patches.

Thanks,

David Daney (2):
   libata: Add two more columns to the ata_timing table.
   libata: New driver for OCTEON SOC Compact Flash interface (v3).

The forthcoming OCTEON SOC Compact Flash driver needs a few more
timing values than were available in the ata_timing table.  I add new
columns for write_hold and read_holdz times.  The values were obtained
from the Compact Flash specification Rev 4.1.

As part of our efforts to get the Cavium OCTEON processor support
merged (see: http://marc.info/?l=linux-mips&m=122834773330212), we
have this CF driver for your consideration.

Most OCTEON variants have *no* DMA or interrupt support on the CF
interface so for these, only PIO is supported.  Although if DMA is
available, we do take advantage of it.

The register definitions are part of the chip support patch set
mentioned above, and are not included here.

In this third version, At the suggestion of Jeff Garzik, I ditched the
attempt to emulate sff bmdma.  For DMA transfers, we just hook the
.qc_issue port op and handle everything ourselves.

Also gone is the mwdmamodes module parameter that as was pointed out
is redundant.

Thanks,

I recently changed plat_mem_setup() or equivalent in my platform code
to not mark the first 32M of memory as BOOT_MEM_ROM_DATA and instead
have the first BOOT_MEM_RAM memory region start at 0.  Here is the two
lines of output from mem_init() for the two different versions:

Memory: 433408k/475136k available (2202k kernel code, 41556k reserved, 690k data, 112k init, 0k highmem)

Memory: 433408k/507904k available (2202k kernel code, 74324k reserved, 689k data, 112k init, 0k highmem)

As you can see, the 32M got added to "reserved" memory (?) and only
added to the right hand number of the "available".  OK, so what does
that mean?  I promised our monkey userspace programmers that they
would have another 32M of memory to slosh around in, but before I
release this change on them I'd like to know what these numbers are
telling me.

This is on 2.6.22 from l.m.o on a Sibyte 1125 in 64bit LE.
CONFIG_FLATMEM=y which was the fashion at the time.

Cheers,

a

Here is a quick'n'dirty solution which I've not tested beyond just
compiling.  It should work but performance will be bad.  Either way, I'm
interested in a test report with X.

(Resend, the linux-mips email address was mangled the first time)
 
Er, it's kind of a good news/bad news joke...

The bad news is that MIPS Linux isn't smart enough, at least as of
2.6.24, to use memory that precedes the kernel.

The good news is that we've got changes that will handle this.

The bad news is that I'm so backed up even getting a basic patchset to
add our platform to the kernel mainline that I don't know how long it
will take until I'm be able to get these additional patches out.

I'll cc the guy who did the changes to see if he can extract a patch for
this.

    Sorry for failing to notice this before but t6z is again the timing that 
the host can't control. Therefore I'm seeig no sense in its addition. I don't 
know how your driver is going to use it -- but most probably incorrectly...

   NAK. I will comment only on the timing setup code now. The rest when 
the time permits (frankly speaking, it doesn't permit me to do even this

   This should be handled in the generic way instead, right in 
ata_pio_need_iordy(). There's nothing Cavium specific in this check, 
just CF specific.

   The t6/t6z timings have nothing to do with -CE at all.

   -DIOx de-assert to -CE de-assert time is t9, not t6, and it ranges 
from 20 to 10 ns, hence you're programming it to 5 ns incorrectly.

  This is t1, address valid to -DIOx setup anmd ranges from 70 to 25 ns 
-- I don't know why you're programming it to a fixed value...

   It's safe to use tkw ISO tkr -- these are minimum timings, not maximum.

   We can add this timing to the table -- it's called tJ if I don't

   Host cannot control tZ timing either.

   This is not a good way to calculate the recovery time. You need the 
cycle/active time "quantized" first, or you'll probably get somewhat 
lengthened resulting cycle...

   Your dma_acks is always 0, so quantizing is uselss.

   Don't leave #if'ed out code please. E.g. convert it to pr_debug()

The host cannot control t6z, but in some cases (like ours) it needs to 
be aware of its value.  We cannot start driving the bus for access to 
other devices until the CF stops driving it.  We need to know how long 
to wait until it is safe to use the bus for other things.

    Re-read the spec please, the timing you need is t9 and it's much longer 
than t6 that your driver using instead.

    OK, t6z is yet longer than t9 but putting it into the table seems 
pointless anyway as it's fixed at 30 ns, at least for the standard 5 PIO modes 
(and for other two modes 30 ns would be good anyway).
    Though frankly speaking I don't quite understand your care for this 
timing, if the ATA standard permits -CE deasserted and data bus being driven 
to overlap. Remember that the minimum address setup time adds to that equation 
too.

It doesn't matter what the ATA standard permits in this case.  We need 
to assure that the OCTEON Boot Bus standard is respected.  There are 
several timing parameters that we have to set based on the documented 
properties of the device.  Ideally if we try to run bus cycles for 
non-ATA/CF devices that share the signal lines of the Boot Bus, they 
should  not interfere with the CF interface.

   Well, your driver is free to handle it on its own, and even respect a 
lesser minimum for PIO5/6. It just doesn't seem practical to add this to 
the table. In fact, about all PATA hardware on market only permits to 
control the active/recovery and the address setup times -- that's why 
the table looks like it looks now.

As part of our efforts to get the Cavium OCTEON processor support
merged (see: http://marc.info/?l=linux-mips&m=122834773330212), we
have this CF driver for your consideration.

Most OCTEON variants have *no* DMA or interrupt support on the CF
interface so for these, only PIO is supported.  Although if DMA is
available, we do take advantage of it.

The register definitions are part of the chip support patch set
mentioned above, and are not included here.

In this forth version, I have tried to address Sergei Shtylyov's
comments reguarding the various timing parameters. .

Thanks,

The forthcoming OCTEON SOC Compact Flash driver needs a few more
timing values than were available in the ata_timing table.  I add new
columns for write_hold and dmack_hold times.  The values were obtained
from the Compact Flash specification Rev 4.1.

As part of our efforts to get the Cavium OCTEON processor support
merged (see: http://marc.info/?l=linux-mips&m=122834773330212), we
have this CF driver for your consideration.

This version is split into three separate patches.  The first adds
some entries to the ata_timing table in libata-core.  The Second adds
some special handling to ata_pio_need_iordy() for Compact Flash
devices, The final patch is is the driver proper.

I will reply with the three patches.

David Daney (3):
   libata: Add two more columns to the ata_timing table.
   libata: Add special ata_pio_need_iordy() handling for Compact Flash.
   libata: New driver for OCTEON SOC Compact Flash interface (v3).

Hi, Ralf,

I have build a new kernel with this patch.
Now I have the resource{0,1} file with permission 600.
However, X is not working yet, since there is an undefined reference in sis's
X driver.

I will try to fix it and report back.

Zhang, Le

It is working now! Just forget to load "vbe" module.

Wonderful, thanks for testing!

Now, my patch doesn't try to handle all the caching modes.  Any mapping
will be uncached which is guaranteed to deliver the lowest possible
performance.  Registers should be mapped uncached but a framebuffer
will usually work best if mapped in uncached accelerated mode.  On
most MIPS implementations the effect of mapping something multiple times
in different caching modes is undefined so that needs to be avoided
which will require some bookkeeping etc.  Too much for 2.6.28 but this
simple solution seems harmless enough to be pushed for 2.6.28 and
-stable.

What about things like _CACHE_UNCACHED_ACCELERATED ? Is there a way to
use this flag ?

That's possible but will require some additional care in the code.
Multiple mappings using different cache modes need to be avoided and
also not all processors support _CACHE_UNCACHED_ACCELERATED.

If you know your software is playing nice and your CPU supports
_CACHE_UNCACHED_ACCELERATED, you can hack the mmap function to use
_CACHE_UNCACHED_ACCELERATED if write_combine is set.  Just for now
and for something which I'm planning to push for 2.6.28 I don't want
anything that's more than trivial.

well, for that, one can always define a Kconfig entry for that. It would
be usefull for using _CACHE_UNCACHED_ACCELERATED in fb_pgprotect in
asm/fb.h too.

Ok, no problem. I'm only asking if it will be possible to use it. For
now, I don't have the pci_mmap_page_range requirement on my systems.

   Well, I don't know what CF 4.1 has but ATA/ATA-2 have minimum -DIOx 
to -DMACK hold time (tJ) for SW DMA modes always 0 ns, and -DIOW data 
hold time (tH) of 50, 30, and 20 for modes 0, 1, and 2 respectfully.

   The comment should be "t4 or tH", to be completely correct.

   Well, the correctness of these values shouldn't matter much because 
IIRC libata have dropped support for SWDMA completely...
