| * | drm/i915: hook up LVDS DPMS propertyJesse Barnes2009-01-22
| | | | | | | | | | | | | | | | | | | | | | | | The LVDS output supports DPMS calls, but we never hooked up the property code, so set property calls didn't actually do anything. Implement a set_property callback for the LVDS output so that the right thing happens. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

* drm/i915: add support for physical memory objectsDave Airlie2009-01-16
| | | | | | | | | | | | | | This is an initial patch to do support for objects which needs physical contiguous main ram, cursors and overlay registers on older chipsets. These objects are bound on cursor bin, like pinning, and we copy the data to/from the backing store object into the real one on attach/detach. notes: possible over the top in attach/detach operations. no overlay support yet.

* drm/i915: Don't allow objects to get bound while VT switched.Eric Anholt2009-01-06
| | | | | | | | | | | | This avoids a BUG_ON in the enter_vt path due to objects being in the GTT when we shouldn't have ever let them be (as we're not supposed to touch the device during that time). This was triggered by a change in the 2D driver to use the GTT mapping of objects after pinning them to improve software fallback performance.

* DRM: i915: add mode setting supportJesse Barnes2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds i915 driver support for the DRM mode setting APIs. Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are supported. HDMI, DisplayPort and additional SDVO output support will follow. Support for the mode setting code is controlled by the new 'modeset' module option. A new config option, CONFIG_DRM_I915_KMS controls the default behavior, and whether a PCI ID list is built into the module for use by user level module utilities. Note that if mode setting is enabled, user level drivers that access display registers directly or that don't use the kernel graphics memory manager will likely corrupt kernel graphics memory, disrupt output configuration (possibly leading to hangs and/or blank displays), and prevent panic/oops messages from appearing. So use caution when enabling this code; be sure your user level code supports the new interfaces. A new SysRq key, 'g', provides emergency support for switching back to the kernel's framebuffer console; which is useful for testing.

* drm: move to kref per-master structures.Dave Airlie2008-12-29
| | | | | | | | | | | | | | | | This is step one towards having multiple masters sharing a drm device in order to get fast-user-switching to work. It splits out the information associated with the drm master into a separate kref counted structure, and allocates this when a master opens the device node. It also allows the current master to abdicate (say while VT switched), and a new master to take over the hardware. It moves the Intel and radeon drivers to using the sarea from within the new master structures. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/i915: GEM on PAE has problems - disable it for now.Dave Airlie2008-12-19
| | | | | | | | | | | On PAE systems, GEM allocates pages using shmem, and passes these pages to be bound into AGP, however the AGP interfaces + the x86 set_memory interfaces all take unsigned long not dma_addr_t. The initial fix for this was a mess, so we need to do this correctly for 2.6.29. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/i915: Don't return busy for buffers left on the flushing list.Eric Anholt2008-12-19
| | | | | | | | | | | | These buffers don't have active rendering still occurring to them, they just need either a flush to be emitted or a retire_requests to occur so that we notice they're done. Return unbusy so that one of the two occurs. The two expected consumers of this interface (OpenGL and libdrm_intel BO cache) both want this behavior.

* drm/i915: Disable the GM965 MSI errata workaround.Keith Packard2008-12-09
| | | | | | | | | | | Since applying the fix suggested by the errata (disabling MSI), we've had issues with interrupts being stuck on despite IIR being 0 on GM965 hardware. Most reporters of the issue have confirmed that turning MSI back on fixes things, and given the difficulties experienced in getting reliable MSI working on Linux, it's believable that the errata was about software issues and not actual hardware issues.

* drm/i915: Don't return error in evict_everything when we get to the end.Owain Ainsworth2008-12-09

* drm/i915: Return error in i915_gem_set_to_gtt_domain if we're not in the GTT.Eric Anholt2008-12-03
| | | | | | | | | It's only for flushing caches appropriately for GTT access, not for actually getting it there. Prevents potential smashing of cpu read/write domains on unbound objects. Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/i915: Retry execbuffer pinning after clearing the GTTKeith Packard2008-12-03
| | | | | | | | | If we fail to pin all of the buffers in an execbuffer request, go through and clear the GTT and try again to see if its just a matter of fragmentation Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/i915: Move the execbuffer domain computations togetherKeith Packard2008-12-03
| | | | | | | | | | | This eliminates the dev_set_domain function and just in-lines it where its used, with the goal of moving the manipulation and use of invalidate_domains and flush_domains closer together. This also avoids calling add_request unless some domain has been flushed.

* drm/i915: Rename object_set_domain to object_set_to_gpu_domainKeith Packard2008-12-03
| | | | | | | | | | | | Now that the CPU and GTT domain operations are isolated to their own functions, the previously general-purpose set_domain function is now used only to set GPU domains. It also has no failure cases, which is important as this eliminates any possible interruption of the computation of new object domains and subsequent emmission of the flushing instructions into the ring.

* drm/i915: Make a single set-to-gtt-domain path.Eric Anholt2008-12-03
| | | | | | | | | This fixes failure to flush caches in the relocation update path, and failure to wait in the set_domain ioctl, each of which could lead to incorrect rendering. Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/i915: If interrupted while setting object domains, still emit the flush.Eric Anholt2008-12-03
| | | | | | | Otherwise, we would leave the objects in an inconsistent state, such as write_domain == 0 but on the flushing list. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/i915: Move flushing list cleanup from flush request retire to request emit.Eric Anholt2008-12-03
| | | | | | | | | | obj_priv->write_domain is "write domain if the GPU went idle now", not "write domain at this moment." By postponing the clear, we confused the concept, required more storage, and potentially emitted more flushes than are required.

* drm/i915: Respect GM965/GM45 bit-17-instead-of-bit-11 option for swizzling.Eric Anholt2008-12-03
| | | | | | | | | | | | | This fixes readpixels and buffer corruption when swapped out and in by disabling tiling on them. Now that we know that the bit 17 mode isn't just a mistake of older chipsets, we'll need to work on a clever fix so that we can get the performance of tiling on these chipsets, but that will require intrusive changes targeted at the next kernel release, not this one.
