2013-11-12Avoid conflicts with Solaris <sys/regset.h> defines that clash with our namesAlan Coopersmith3-1/+30
When building on Solaris with _XOPEN_SOURCE set to a recent XPG release, <stdlib.h> and other core headers start including <sys/regset.h>, which has a bunch of unfortunately named macros such as "CS", "ES", etc. for x86 & x64 registers which clash with existing variable & struct member names in Xorg - so #undef these so they don't interfere with our use. (Yes, have filed a bug against the system headers for exposing these, but this solves the problem for building on existing releases.)

2012-03-21Introduce a consistent coding styleKeith Packard20-5207/+6193
This is strictly the application of the script 'x-indent-all.sh' from util/modular. Compared to the patch that Daniel posted in January, I've added a few indent flags: -bap -psl -T PrivatePtr -T pmWait -T _XFUNCPROTOBEGIN -T _XFUNCPROTOEND -T _X_EXPORT The typedefs were needed to make the output of sdksyms.sh match the previous output, otherwise, the code is formatted badly enough that sdksyms.sh generates incorrect output. The generated code was compared with the previous version and found to be essentially identical -- "assert" line numbers and BUILD_TIME were the only differences found. The comparison was done with this script: dir1=$1 dir2=$2 for dir in $dir1 $dir2; do (cd $dir && find . -name '*.o' | while read file; do dir=`dirname $file` base=`basename $file .o` dump=$dir/$base.dump objdump -d $file > $dump done) done find $dir1 -name '*.dump' | while read dump; do otherdump=`echo $dump | sed "s;$dir1;$dir2;"` diff -u $dump $otherdump done Signed-off-by: Keith Packard <keithp@keithp.com> Acked-by: Daniel Stone <daniel@fooishbar.org> Acked-by: Alan Coopersmith <alan.coopersmith@oracle.com>

2011-09-15x86emu: There is no NO_INLINE implementation of unaligned access here.Jamey Sharp1-2/+0
Patch produced with: unifdef -UNO_INLINE -B This change isn't relevant to the similar code in hw/xfree86/common/compiler.h, because x86emu is expected to someday move out of xserver entirely and so should not depend on any xserver headers. Also, some platforms apparently do have NO_INLINE versions of compiler.h.

2010-11-10x86emu: fix jump_near_IMM to handle DATA: flag correctly.Luc Verhaegen1-6/+14
Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=24348 Before (data flag ignored -> broken): 66 DATA: e944f1 JMP 1ff6 After (fixed): 66 DATA: e944f1ffff JMP 00001ff8 This subtle difference in the length of decoded instruction meant that the VBE call jumped to the routine setting AX=0x14F (VBE Failed) instead of the routine that set AX=0x4F (VBE success). The ability to run the same code in vm86 significantly aided the debugging of this issue. Those X.org developers who would like to drop vm86 better take special care towards _all_ vesa bugs, as those will expose further issues. Patch applies easily to even xserver 1.4.2.

Spiritual revert of 1fa4de80fcfc697b5e5879cc351fb3e9dbf6acbe. Intel's C compiler claims to be gcc-compatible; if they're not defining the same macros as gcc then that's their bug, not ours. Even if we were to do this aliasing we should do it once and for all in servermd.h.

Yes, this is a 486+ instruction and thus not strictly legal in vm86 mode, but enough BIOSes use it (looking at you VIA) that we might as well implement it.

2008-02-08X86EMU: handle CPUID instructionBart Trojanowski4-1/+161
After trying to switch from X to VT (or just quit) the video-amd driver attempts to issue INT 10/0 to go to mode 3 (VGA). The emulator, running the BIOS code, would then spit out: c000:0282: A2 ILLEGAL EXTENDED X86 OPCODE! The opcode was 0F A2, or CPUID; it was not implemented in the emulator. This simple patch, against 1.3.0.0, handles the CPUID instruction in one of two ways: 1) if ran on __i386__ or __x86_64__ then it calls the CPUID instruction directly. 2) if ran elsewhere it returns a canned 486dx4 set of values for function 1. This fix allows the video-amd driver to switch back to console mode, with the GSW BIOS.
