2010-09-26Retry framebuffer allocation if first attempt fails.Chris Wilson
If we are tiled, we may fail the allocation due to an EIO and so not being able to set tiling. Try again with an untiled request in this case. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-09-26Disable dri2 after forcing fallbacksChris Wilson
If we force fallbacks, then we will only create pixmaps in system memory, preventing DRI2 from passing valid bo names to the clients. In this case, they will just fallback to swrast. If we disable DRI2 after forcing fallbacks (e.g. regenerating after a GPU hang or explicitly disabled with the shadow buffer) then it is simpler just to disable the extension and allow mesa to use pure swrast.

2010-09-08Enable a shadow buffer and disable GPU acceleration.Chris Wilson
An attempt to workaround the incoherency in gen2 chipsets, we avoid using dynamic reallocation as much as possible. The first step is to disable allocation of pixmaps using GEM and simply create them in system memory without a backing buffer object. This forces all rendering to use S/W fallbacks. The second step is to allocate a shadow front buffer and assign that to the Screen pixmap. This ensure that the front buffer remains in the GTT and pinned for scanout. The shadow buffer will be rendered to in the normal fashion via the Screen pixmap, and be marked dirty. In the block handler, the dirty shadow buffer is then blitted (using the GPU) over the front buffer. This should completely avoid having to move pages around in the GTT and avoid incurring the wrath of those early chipsets. Secondly, performance should be reasonable as we avoid the ping-pong caused by the small aperture and weak GPU forcing software fallbacks. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-09-07display: Query current level after finding max value.Chris Wilson
The current backlight value is clamped to the valid range [0, max] and so as we queried the value before setting the max, we forced the current backlight to 0 and so set it to be zero on initialising the display. Fixes: Bug 30063 - start X will modify brightness value to zero https://bugs.freedesktop.org/show_bug.cgi?id=30063 which is a regression due to 38f940dfea494d3093236f065392c431be06ae6e.

2010-09-04display: Set MONITOR_EDID_COMPLETE_RAWDATA for large EDIDsChris Wilson
Quoting Adam Jackson: "But the X driver looks like it never sets MONITOR_EDID_COMPLETE_RAWDATA, which means the X core doesn't know that any sections beyond the first are present, so it won't ever hand back more than 128 bytes to clients. Boo." This patch is based on his. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-09-04Force use of GTT and fence registers for mapping tiled objectsChris Wilson

2010-08-26Revert "Leave adjustment of backlight to the driver."Chris Wilson
This reverts commit 9c3e34703dcdc2155faeb2c1886930def19d9989. This commit is not ready, as first the driver needs to handle all controllers, especially those that ignore the BLC and require their own interface. Fortunately, by moving that discovery into the kernel - where it just means finding which ACPI device is attached to the video and has a backlight interface - the userspace code should become much more sane, and work even with multi-gpu, multi-lid systems. But that is for tomorrow.

2010-07-30Remove explicit batchbuffer submit in DRI2 copyregionKristian Høgsberg
Now that we submit from the flush callback chain, we know we'll always submit before the client receives the reply or event that blocks it from rendering the next frame.
2010-07-30Submit batch buffers from flush callback chainKristian Høgsberg
There are a few cases where the server will flush client output buffers but our block handler only catches the most common (before going into select). If the server flushes client buffers before we submit our batch buffer, the client may receive a damage event for rendering that hasn't happened yet. Instead, we can hook into the flush callback chain, which the server will invoke just before flushing output. This lets us submit batch buffers before sending out events, preserving ordering.

2010-07-26video: kernel overlay needs triple bufferingDaniel Vetter
The kernel overlay code does asynchronous overlay flips.

2010-07-24simplify Makefile as per-target compilation flags are not neededGaetan Nadon
Per-target compilation flags (libIntelXvMC_la_CFLAGS) are required when multiple targets which require different compiler flags, are build in the same makefile. Automake issues a command with -c and -o flags which not all compilers support. The object fles are prefixed with libIntelXvMC_la. The macro AM_PROG_CC_C_O must then be used to provide this feature on compilers that do not have it. If not, a warning is issued at make time. This macros checks for compiler support and if missing, uses a "compile" script it generates in the package root directory. Currently the driver uses per-target flags but the macro is missing. Rather than adding the macro, this patch stops using per-target flags by using the AM_CFLAGS variable for all targets in the makefile, as there is only one.
