I'm porting kernel 2.4.1 to galileo evaluation boards, I'v used an old binaries from oss.sgi.com ftp site (Redhat version 5.0 RPMs) and worked great on kernel 2.2.14 with QED 5271 CPU.
Now i'm testing the system with kernel 2.4.1 with QED 7000A CPU but when trying to run /bin/sh for example it writes - (I'v added init=/bin/sh in the command line) -

IP-Config: Guessing netmask 255.0.0.0
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
Looking up port of RPC 100003/2 on 10.2.40.2

Freeing unused kernel memory: 44k freed
[sh:1] Illegal instruction 8fe30014 at 7ffffc34 ra=00000001

it is really weird because at address 7ffffc34 is the stack for the process, and no instruction should run from there !!! That means that the kernel shouldn't have printed the 'Illegal instruction' message !


Did any one had this problem ? Any suggestions ?

Regards,
Rabeeh

That means that > the kernel shouldn't have printed the 'Illegal instruction' message ! What eval board is this? > Did any one had this problem ? Any suggestions ? Yes, with the ev96100. I had to modify rm7k.c to add r4k-like cache routines for the r7k. With those routines, the ev96100 (r7k cpu) runs with the seconday cache enabled. I recently sent a newer ev96100 patch to Ralf, which brought the ev96100 support up to 2.4.1, but the patch did not include rm7k.c because Ralf says that those routines are not necessary. The rest of the patch doesn't seem to have been committed yet. There is a test9 based linux support package for the ev96100 on ftp.mvista.com:/pub/Area51/ev96100.

If there are any problems with the MIPS support now is the time to tell me. I'm especially interesting in strace reporting umoven() errors while tracing a program.

Conincidentally I today built strace-cvs for MIPS before receiving your message and found it to be working just fine. The only bug which my last several month old build from an older snapshot doesn't have is that syscall 4129 (from memory, number may be incorrect) gets decoded as a syscall with very many arguments (~ 20). Will have to look into it.

Hmm, 4129 is delete_module, which is handled exactly like sys_chdir (syscal with one string argument). Looking at the syscall table I can't find any syscall with that many argument, the highest number I can find is 6 (mmap, recvfrom and sendto).

Patch against 2.4.2 to remove cpu_bh_enable/disable, now it is only called from the same include file. Define *_current versions of softirq_active, softirq_mask, local_irq_count, local_bh_count, syscall_count, nmi_count. Some architectures can access the current cpu's data without doing an array lookup, they will be able to use the *_current form for speed after this patch is in. diff -ur 2.4.2-pristine/include/asm-alpha/softirq.h 2.4.2-softirq/include/asm-alpha/softirq.h --- 2.4.2-pristine/include/asm-alpha/softirq.h Mon Aug 7 05:42:21 2000 +++ 2.4.2-softirq/include/asm-alpha/softirq.h Mon Feb 26 14:37:46 2001 @@ -5,21 +5,7 @@ #include #include -extern inline void cpu_bh_disable(int cpu) -{ - local_bh_count(cpu)++;
