[MIPS] Cleanup memory managment initialization. · 2925aba4

Ralf Baechle authored Jun 18, 2006

Historically plat_mem_setup did the entire platform initialization. This
was rather impractical because it meant plat_mem_setup had to get away
without any kind of memory allocator. To keep old code from breaking
plat_setup was just renamed to plat_setup and a second platform
initialization hook for anything else was introduced.

[MIPS] Drop 0 definition for kern_addr_valid · d9b8d0da

Ralf Baechle authored Jun 12, 2006

kern_addr_valid is currently only being used in kmem_ptr_validate which
is making some vague attempt at verfying the validity of an address.
Only IA-64, PARISC and x86-64 actually make some actual effort to verify
the validity of the pointer. Most architecture definitions of
kern_addr_valid() just define it as 1; the Alpha and CONFIG_DISCONTIGMEM
on i386 and MIPS even as 0; the 0-definition will result in
kmem_ptr_validate always failing which in turn will cause d_validate to
always fail. d_validate's only two users are smbfs and ncpfs, so the
0 definition ended breaking those ...

[MIPS] Fix futex_atomic_op_inuser. · 0307e8d0

Atsushi Nemoto authored Jun 11, 2006

I found that NPTL's pthread_cond_signal() does not work properly on
kernels compiled by gcc 4.1.x.  I suppose inline asm for
__futex_atomic_op() was wrong.  I suppose:

1. "=&r" constraint should be used for oldval.
2. Instead of "r" (uaddr), "=R" (*uaddr) for output and "R" (*uaddr)
   for input should be used.
3. "memory" should be added to the clobber list.

[PATCH] Fix BCM1480 doubled process accounting times. · e1701fb2

[MIPS] James E Wilson authored Feb 27, 2006

Running a UP kernel on a bcm1480 board, I get nonsensical timing
results, like this:
release@unknown:~/tmp$ time ./a.out
real    0m22.906s
user    0m45.792s
sys     0m0.010s
According to my watch, this program took 23 seconds to run, so the real
time clock is OK.  It is process accounting that is broken.

I tracked this down to a problem with the function
bcm1480_timer_interrupt in the file sibyte/bcm1480/time.c.  This
function calls ll_timer_interrupt for cpu0, and ll_local_timer_interrupt
for all cpus.  However, both of these functions do process accounting.
Thus processes running on cpu0 end up with doubled times.  This is very
obvious in a UP kernel where all processes run on cpu0.

The correct way to do this is to only call ll_local_timer interrupt if
this is not cpu0.  This can be seen in the mips-board/generic/time.c
file, and also in the sibyte/sb1250/time.c file, both of which handle
this correctly.  I fixed the bcm1480/time.c file by copying over the
correct code from the sb1250/time.c file.

With this fix, I now get sensible results.
