2010-12-05Don't use hardware acceleration on Sandybridge rev 07 hardware or earlier.Matthias Hopf

2010-11-23Disable BLT for i830 and 845GChris Wilson
This pair of chipsets seem broken beyond repair, specifically the erratum that causes the wrong PTE entry to be invalidated, so disable our incorrect attempts to use the BLT on those devices. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-11-03Fallback to shadow for Sandybridge if we don't have access to the BLTChris Wilson
If we attempt to emit BLT batches without kernel support, we just end up with EINVAL and no rendering. Prevent this, and avoid uncached rendering, by restoring the shadow fallback paths if there is no BLT support. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-11-02Remove the intermittent GEM_THROTTLE call.Eric Anholt
This is a holdover from early GEM work when we weren't syncing on the DRI client side. It would keep clients from getting too far ahead and killing their interactivity, by bringing everyone to a halt when anyone was too far ahead. Now, GL clients throttle themselves to avoid the problem, and it turns out that in the case that they don't (long rendering to buffers with no swap), this actually reduces X Server interactivity: instead of lagging of X rendering behind input, you get no response for seconds at a time, then a burst of rendering, then nothing again. Reported by ajax. Tested with moving a window while running cairo-perf-trace on the GL backend (improvement) and X backend (no significant change in responsiveness).

2010-10-22intel: Listen for hotplug uevents (V3)Adam Jackson
This connects the kernel uevent indicating monitor hotplugging to the RandR notification events so that X applications can be notified automatically when monitors are connected or disconnected. This also adds a configuration option to disable hotplug events.

2010-10-04shadow: Enable shadow by default on SandyBridgeChris Wilson
SandyBridge 2D support is far from complete, so instead of permanently falling back and always using uncached GTT mapping for rendering, use the shadow buffer instead. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-10-04shadow+dri2: Allow dri2 to be independently enabled with shadowChris Wilson
To enable DRI we create GEM buffers for the client to render into with hardware acceleration. In order to maintain coherency between any 2D render operations with the independent 3D clients (this includes the reading of 2D rasterisation by the direct rendering client, e.g. compiz using texture_from_pixmap) we need to replace the shadow pixmap with the GTT mapping. Therefore 2D rendering to a DRI buffer will be to uncached memory and thus penalised -- but the direct rendering clients will have full hardware acceleration.

2010-10-02Do not claim the PCI device if !KMSChris Wilson
By returning FALSE whilst probing if we can't find a KMS driver, we allow X to fallback to trying the VESA driver -- rather than failing. The initial idea for this was by Julien Cristau. Reported-by: Julien Cristau <jcristau@debian.org> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-09-30Always use tiling on SandybridgeZhenyu Wang
Sandybridge requires kind of buffer must be tiling, like depth. And we would or have all tiling cases handled fine. So not allow user to turn off tiling on Sandybridge+ may be fine. Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
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.

2010-09-10shadow: Simply modify the Screen pixmap headerChris Wilson
This is a slightly less risky strategy than having to remember to update all pointers to the old Screen pixmap. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
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>
2010-08-19Open-code DRICreatePCIBusID()Chris Wilson
During -configure we would attempt to query the availablility of KMS before the DRI module was loaded, thus we were unable to create a valid bus identifier and so the query failed and we disowned the device.

2010-08-18Move registration of vsync fd from pre-init to screen-initChris Wilson
Marty Jack reported an issue he found where the page-flipping handler was being lost on server reset. This results in the swap completion notification being lost, with the sporadic hang of full screen applications like Compiz, flash and even glxgears! Fixes: Bug 29584 - Server in compute loop https://bugs.freedesktop.org/show_bug.cgi?id=29584 There are also several possibly related bugs with similar symptoms, i.e. OpenGL applications hanging on missed swap notifications.

2010-08-01Rename drmmode_display to intel_displayChris Wilson
And fixup all the drmmode_* functions to have an intel prefix and categorise those into intel_mode, intel_crtc, intel_output and intel_property so that the functions are a little more self-descriptive and, more importantly, are consistent. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
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.

In order to cleanup all CRTCs and outputs on shutdown, we need to keep a list of the individual structures and iterate over that list on shutdown. Also, the output and crtcs are configured just once and not for each screen generation so move the shutdown to the termination and not on CloseScreen. Oops.
