2008-04-22linux-core Makefile: add GIT_REVISIONPekka Paalanen
This tries to automatically fetch a git revision string and if succeeds, it #defines GIT_REVISION string macro. Packagers can override it by 'make GIT_REVISION=foo'. Update Nouveau to use GIT_REVISION, if defined, instead of DRIVER_DATE in struct drm_driver. Signed-off-by: Pekka Paalanen <pq@iki.fi>
2008-04-17Porting DVO stuffHong Liu
Ported from Xorg intel 2d driver. Changed interfaces definitions, which needed to be changed later if other device wants to use these DVO stuff.
2008-04-14Fix buffer object map wait error.Thomas Hellstrom
Add some branch prediction hints.
2008-04-14Fix buffer object creation validation.Thomas Hellstrom
BO lock fixes.
2008-04-14Unlock the BO mutex while waiting for idle, unmapped, unfenced.Thomas Hellstrom
Move unfenced checking into idle checking. Never time out while waiting for software events like unmapped or unfenced.

2008-04-10Fixup Intel TV property codeJesse Barnes
Use the new TV property creation routine and fixup the set_property code to actually do a mode set call when properties change.
2008-04-10Split TV property creation into its own routineJesse Barnes
It needs to take arguments from the caller about supported TV formats, so declare it in drm_crtc.h and export it.
2008-04-10Remove structure fields & codeJesse Barnes
Cleanup some random cruft left over from the initial port.
2008-04-10Fix masking in get_load_detect_pipeJesse Barnes
Start i at -1 so that the masking works right.
2008-04-10Keep display info in struct display_infoJesse Barnes
Some fields had snuck into the drm_output structure. Put them back and fill in more stuff from the EDID block.
2008-04-09Fix TV load detectionJesse Barnes
Now that we can allocate load detect pipes, we can perform TV out load detection correctly. Call the new routines and enable proper TV detection.
2008-04-09Port pipe reservation code for load detectionJesse Barnes
TV out needs to do load detection, which means we have to find an available pipe to use for the detection. Port over the pipe reservation code for this purpose.

2008-04-09Older kernels don't have kobject_uevent_env(), so puntAlan Hourihane
the event for these older kernels.
2008-04-09Fixup sysfs output registrationJesse Barnes
Put off registering new outputs with sysfs until they're properly configured, or we may get duplicates if the type hasn't been set yet (as is the case with SDVO initialization). This also means moving de-registration into the cleanup function instead of output destroy, since the latter occurs during the normal course of setup when an output isn't found (and therefore not registered with sysfs yet.

2008-04-08Improved DRM sysfs supportJesse Barnes
This patch ties outputs, output properties and hotplug events into the DRM core. Each output has a corresponding directory under the primary DRM device (usually card0) containing dpms, edid, modes, and connection status files. New hotplug change events occur when outputs are added or hotplug events are detected.

2008-03-30[i915] Report buffer state _after_ fence submission to user-space.Thomas Hellstrom
This fixes a problem where the wrong bo->fence_type was reported, and also saves some memory space. [bo core] export the drm_bo_fill_rep_arg function.

Fix that got left out after the intel-post-reloc merge.

this may not survive long - just need something for testing
2008-03-17drm: pick correct master for cleaning upDave Airlie
When a master is exiting, make sure we clean it up and not the currently in charge master.

When destroying DRI sarea, make sure you use the master associated with the sarea and not the one currently in charge
2008-03-17drm/pcigart: fix the pci gart to use the drm_pci wrapper.Dave Airlie
This is the correct fix for the RS690 and hopefully the dma coherent work. For now we limit everybody to a 32-bit DMA mask but it is possible for RS690 to use a 40-bit DMA mask for the GART table itself, and the PCIE cards can use 40-bits for the table entries.

2008-03-14drm: Fix race that can lockup the kernelMike Isely
The i915_vblank_swap() function schedules an automatic buffer swap upon receipt of the vertical sync interrupt. Such an operation is lengthy so it can't be allowed to happen in normal interrupt context, thus the DRM implements this by scheduling the work in a kernel softirq-scheduled tasklet. In order for the buffer swap to work safely, the DRM's central lock must be taken, via a call to drm_lock_take() located in drivers/char/drm/drm_irq.c within the function drm_locked_tasklet_func(). The lock-taking logic uses a non-interrupt-blocking spinlock to implement the manipulations needed to take the lock. This semantic would be safe if all attempts to use the spinlock only happen from process context. However this buffer swap happens from softirq context which is really a form of interrupt context. Thus we have an unsafe situation, in that drm_locked_tasklet_func() can block on a spinlock already taken by a thread in process context which will never get scheduled again because of the blocked softirq tasklet. This wedges the kernel hard. To trigger this bug, run a dual-head cloned mode configuration which uses the i915 drm, then execute an opengl application which synchronizes buffer swaps against the vertical sync interrupt. In my testing, a lockup always results after running anywhere from 5 minutes to an hour and a half. I believe dual-head is needed to really trigger the problem because then the vertical sync interrupt handling is no longer predictable (due to being interrupt-sourced from two different heads running at different speeds). This raises the probability of the tasklet trying to run while the userspace DRI is doing things to the GPU (and manipulating the DRM lock). The fix is to change the relevant spinlock semantics to be the interrupt-blocking form. After this change I am no longer able to trigger the lockup; the longest test run so far was 20 hours (test stopped after that point). Note: I have examined the places where this spinlock is being employed; all are reasonably short bounded sequences and should be suitable for interrupts being blocked without impacting overall kernel interrupt response latency.
