2010-03-06linux-user: Fix syscall pipe2() retval on sh4takasi-y@ops.dti.ne.jp
On linux/sh4 pipe() return values by r0:r1 as SH C calling convention. pipe2() return values on memory as traditional unix way. Signed-off-by: Takashi YOSHII <takasi-y@ops.dti.ne.jp> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-28alpha-linux-user: Implement signals.Richard Henderson
Move userland PALcode handling into linux-user main loop so that we can send signals from there. This also makes alpha_palcode.c system-level only, so don't build it for userland. Add defines for GENTRAP PALcall mapping to signals. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-06linux-user: adapt uname machine to emulated CPULoïc Minier
This patch for linux-user adapts the output of the emulated uname() syscall to match the configured CPU. Tested with x86, x86-64 and arm emulation. Signed-off-by: Riku Voipio <riku.voipio@iki.fi> Signed-off-by: Loïc Minier <lool@dooz.org>
2010-01-14alpha: fix stat64 issueVince Weaver
The stat64/fstat64 syscalls are broken for alpha linux-user. This is because Alpha, even though it is native 64-bits, has a stat64 syscall that is different than regular stat. This means that the "TARGET_LONG_BITS==64" check in syscall.c isn't enough. Below is a patch that fixes things for me, although it might not be the cleanest fix. This issue keeps sixtrack and fma3d spec2k benchmarks from running.

2009-12-13target-alpha: Fixes for alpha-linux syscalls.Richard Henderson
1. Add correct definitions of error numbers. 2. Implement SYS_osf_sigprocmask 3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL. This last requires exposing the FPCR value to do_syscall. Since this value is actually split up into the float_status, expose routines from helper.c to access it. Finally, also add a float_exception_mask field to float_status. We don't actually use it to control delivery of exceptions to the emulator yet, but simply hold the value that we placed there when loading/storing the FPCR.

b55a37c981914aa8ecd21b9a2a2fb37f39b917c5 moved the call to cpu_reset to user emulators. But cpu_copy also initializes a CPU structure, so add the call also there. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-08-25linux-user: zero fstat buffer to initialize nsec fieldsUlrich Hecht
The fstat implementation does not initialize the nanosecond fields in the stat buffer; this caused funny values to turn up there, preventing, for instance, cp -p from preserving timestamps because utimensat rejected the out-of-bounds nanosecond values.

2009-06-16Return EOPNOTSUPP instead of ENOSYS for *xattr* syscallsArnaud Patard
In current code, we're sending ENOSYS to target when a syscall for the xattrs is done. This makes applications like ls complain loudly about that and breaks scripts parsing the output.

2009-06-04fix gdbstub support for multiple threads in usermode, v3Nathan Froyd
When debugging multi-threaded programs, QEMU's gdb stub would report the correct number of threads (the qfThreadInfo and qsThreadInfo packets). However, the stub was unable to actually switch between threads (the T packet), since it would report every thread except the first as being dead. Furthermore, the stub relied upon cpu_index as a reliable means of assigning IDs to the threads. This was a bad idea; if you have this sequence of events: initial thread created new thread #1 new thread #2 thread #1 exits new thread #3 thread #3 will have the same cpu_index as thread #1, which would confuse GDB. (This problem is partly due to the remote protocol not having a good way to send thread creation/destruction events.) We fix this by using the host thread ID for the identifier passed to GDB when debugging a multi-threaded userspace program. The thread ID might wrap, but the same sort of problems with wrapping thread IDs would come up with debugging programs natively, so this doesn't represent a problem.
