If I change DefaultColorDepth 24 to 16 - beryl works. and 32 bpp not supported, at least X don't start in this case, complaining about unsupported (by hardware) depth.
Created attachment 11835 [details] [review] xserver patch Created attachment 11836 [details] [review] xf86-video-intel patch Do these patches fix the problem? (In reply to comment #4) > Created an attachment (id=11836) [details] > xf86-video-intel patch > > Do these patches fix the problem? > I think no, mostly because now i915tex is unified with plain i915 on dri side, and with current ddx (buffer objects for everything) dri don't work at all on my i845. And old dri/drm don't work without recompiling x-server against old drm/mesa stuff... Because this particular feature is much lower on my to-do list for testing - i'll wait for working dri/aiglx with new drivers instead of downgrading everything. Thanks for patches, i'll keep them until better day coming :) i915tex is gone. would you please test on the git upstream to see if this bug still exist? If yes, would you please open another bug to track? I'll mark this bug as wontfix... thanks! The unified i915 driver still has the same code. FWIW, current xserver has a patch which allows the driver to return ~0ULL to indicate that the pixmap can't be used directly. Is this still an issue with DRI2? Sorry, I don't have this hardware anymore ... OK, we'll go ahead and close it then. |

Today I've tried new SetTexOffset hook. (X server 1.4 + self-compiled xf86-video-intel from Aug, 16 2007 + self-compiled mesa from 4 Sept 2007). Linux kernel 2.6.21.7 Drm from git, up to commit 06bb07259531d10df2c1979919af899e3812057b My hardware is: 00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01) (prog-if 00 [VGA]) Subsystem: Micro-Star International Co., Ltd. Unknown device 5808 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at d0000000 (32-bit, prefetchable) [size=128M] Memory at dff80000 (32-bit, non-prefetchable) [size=512K] Capabilities: [d0] Power Management version 1 beryl - 0.2.1 It works fine with 16 bpp screen depth. But display nothing in 24 bpp mode. And i forced to reboot my machine via ACPI poweroff. Probably this is related to this comment, found in i830_render.c I830FALLBACK("830/845G don't support a8, x8r8g8b8, x8b8g8r8\n"); (in src/mesa/drivers/dri/i915tex/i830_texstate.c I can see lines like this: if (intelObj->imageOverride) { i830->state.tex_buffer[unit] = NULL; i830->state.tex_offset[unit] = intelObj->textureOffset; switch (intelObj->depthOverride) { case 32: format = MAPSURF_32BIT | MT_32BIT_ARGB8888; break; case 24: default: format = MAPSURF_32BIT | MT_32BIT_XRGB8888; break; case 16: format = MAPSURF_16BIT | MT_16BIT_RGB565; break; } )
