http://bugs.freedesktop.org/show_bug.cgi?id=20305 Summary: Unending loop in R600OverlapCopy() [srcX == dstX && srcY == dstY] Product: xorg Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: high Component: Driver/radeonhd AssignedTo: lverhaegen@suse.de ReportedBy: darkjames@darkjames.ath.cx QAContact: xorg-team@lists.x.org Hi, I'm using r6xx-r7xx-support branch (commit 3f8b6ecc), with EXA AccelMethod. Recently when I want to save file in openoffice I typed 1 letter and my Xorg freeze. Luckily I've got sshd started and I could attach strace and gdb to it. gdb backtrace: #4 0x00007fbb0e9433c7 in R600OverlapCopy (pDst=0x861950, srcX=820, srcY=571, dstX=820, dstY=571, w=16, h=19) at r600_exa.c:816 pScrn = (ScrnInfoPtr) 0x817bf0 rhdPtr = (RHDPtr) 0x817810 accel_state = (struct r6xx_accel_state *) 0x83c360 dst_pitch = 1408 dst_offset = 3489693696 i = 0 hchunk = 0 vchunk = 0 #5 0x00007fbb0e9437af in R600Copy (pDst=0x861950, srcX=820, srcY=571, dstX=820, dstY=571, w=16, h=19) at r600_exa.c:875 pScrn = (ScrnInfoPtr) 0x817bf0 rhdPtr = (RHDPtr) 0x817810 accel_state = (struct r6xx_accel_state *) 0x83c360 In frame #4 hchunk == 0, so this loop: 815 for (i = 0; i < w; i += hchunk) { 816 R600DoPrepareCopy(pScrn, 817 dst_pitch, pDst->drawable.width, pDst->drawable.height, dst_offset, pDst->drawable.bitsPerPixel, 818 dst_pitch, pDst->drawable.height, dst_offset, pDst->drawable.bitsPerPixel, 819 accel_state->rop, accel_state->planemask); 821 R600AppendCopyVertex(pScrn, srcX + i, srcY, dstX + i, dstY, hchunk, h); 822 R600DoCopy(pScrn); 823 } is unending. I dunno how R600OverlapCopy() should work when (srcX == dstX) && (srcY == dstY), so no patch.
