Re: Broadcom 440x support?

2003-02-22 Thread Stefan Eßer
There are Linux drivers available for download and it seems,
that the 440x and 520x drivers are very similar. I intended
to make the bge driver support the 440x in my ASUS A7K8X, but 
have not had time to actually start that project (beyond the
initial diff of the two official drivers.)

If anybody is interested, I can provide the diffs, which 
amount to 2620 lines (diff -u1). But many differences are
cosmetic (b44_ prepended to function names and bcm5700
replaced by bcm4400 in many identifiers). The actual driver
change will probably amount to just a few hundred lines,
at most ...

Re: Raising SIGSEGV in SIGSEGV handler makes FreeBSD loop

  Besides, this doesn't explain anything. I see I haven't asked any question in

 Because POSIX mandates that it do so?
 
 man 3 signal tells us:
 
  The handled signal is unblocked when the function returns and the process
  continues from where it left off when the signal occurred.  Unlike previ-
  ous signal facilities, the handler func() remains installed after a sig-
  nal has been delivered.

POSIX mandates no such thing.  You missed the part of the POSIX spec
that says:

The behavior of a process is undefined after it returns normally
from a signal-catching function for a SIGFPE, SIGILL, SIGSEGV,
or SIGBUS signal that was not generated by the kill() function,
the sigqueue() function, or the raise() function as defined by
the C Standard.

It's in ANSI/IEEE Std 1003.1 section 3.3.1.3.

POSIX permits the FreeBSD behavior but does not mandate it.

Replacement for get_user_pages() of Linux

2003-02-22 Thread Byunghyun Oh
I'm porting Plex86 x86 VM, which uses get_user_pages() function at
Linux-version kernel module to find and pin physical pages of memory
in user space (according to its documentation). I tried many
candidates as its replacement (PHYS_TO_VM_PAGE() macro in vm/vm_page.h
seems most useful now), but they haven't worked at all.

Any experience about porting VM-related things in Linux will be
appreciated. :)
