Hi, I have two proposals for the alpha-kernel.
1:
The stack size for alpha is limited to a small value,
and I think we sould update the asm-alpha/resource.h for
a bigger value. I greped in the 2.2.14 kernel source, and
found that only a few architecture has limited stack size.
# grep STK */resource.h
asm-alpha/resource.h: {_STK_LIM, _STK_LIM}, /* RLIMIT_STACK */ \
asm-arm/resource.h: { _STK_LIM, _STK_LIM }, \
asm-i386/resource.h: { _STK_LIM, LONG_MAX }, \
asm-m68k/resource.h: {_STK_LIM, LONG_MAX}, \
asm-mips/resource.h: {_STK_LIM, _STK_LIM}, \
asm-ppc/resource.h: {_STK_LIM, LONG_MAX}, /* RLIMIT_STACK */ \
asm/resource.h: {_STK_LIM, _STK_LIM}, /* RLIMIT_STACK */ \
asm-sparc64/resource.h: {LONG_MAX, LONG_MAX}, {_STK_LIM, LONG_MAX}, \
asm-sparc/resource.h: {LONG_MAX, LONG_MAX}, {_STK_LIM, LONG_MAX}, \
2:
The SHMMAX in shmparam.h is set to 0x3fa000.
And when I run the cdrecord which was in the debian package, the
program claimed me that it could not get enough shared memory.
I patched the value to 0xffa000, and then the program worked fine.
In other architectues, the value set to the bigger value, and
I think alpha can also have a bigger default value to the SHMMAX.
Any comment?
