| * drm/i915: Allow tiling of objects with bit 17 swizzling by the CPU.Eric Anholt2009-04-081-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | Save the bit 17 state of the pages when freeing the page list, and reswizzle them if necessary when rebinding the pages (in case they were swapped out). Since we have userland with expectations that the swizzle enums let it pread and pwrite contents accurately, we can't expose a new swizzle enum for bit 17 (which it would have to GTT map to handle), so we handle it down in pread and pwrite by swizzling the copy when bit 17 of the page address is set.

| * drm/i915: Implement batch and ring buffer dumpingBen Gamari2009-04-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We create a debugfs node (i915_ringbuffer_data) to expose a hex dump of the ring buffer itself. We also expose another debugfs node (i915_ringbuffer_info) with information on the state (i.e. head, tail addresses) of the ringbuffer. For batchbuffer dumping, we look at the device's active_list, dumping each object which has I915_GEM_DOMAIN_COMMAND in its read domains. This is all exposed through the dri/i915_batchbuffers debugfs file with a header for each object (giving the objects gtt_offset so that it can be matched against the offset given in the BATCH_BUFFER_START command.

* DRM: i915: add mode setting supportJesse Barnes2008-12-291-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Airlie2008-12-291-2/+8
| | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | 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.

* i915: Remove racy delayed vblank swap ioctl.Eric Anholt2008-11-111-15/+0
| | | | | | | | | | | | | | | | | | When userland detected that this ioctl was supported (by version number check), it used it in a racy way -- dispatch delayed swap, wait for vblank, continue rendering. As there was no mechanism for it to wait for the swap to finish, sometimes it would render before the swap and garbage would be displayed on the screen. By removing the ioctl and returning -EINVAL, userland returns to its previous, correct rendering path of waiting for a vblank then dispatching a swap. The only path that could have used this ioctl correctly was page flipping, which relied on only one client running and emitting wait-for-vblank-before-rendering in the command stream. That path also falls back correctly, at the performance cost of not being able to queue up rendering before the flip occurs.

* drm/i915: hold dev->struct_mutex and DRM lock during vblank ring operationsKeith Packard2008-10-231-5/+5
| | | | | | | | | | | | | | | | | | | | To synchronize clip lists with the X server, the DRM lock must be held while looking at drawable clip lists. To synchronize with other ring access, the ring mutex must be held while inserting commands into the ring. Failure to do the first resulted in easy visual corruption when moving windows, and the second could have corrupted the ring with DRI2. Grabbing the DRM lock involves using the DRM tasklet mechanism, grabbing the ring mutex means potentially sleeping. Deal with both of these by always running the tasklet from a work handler. Also, protect from clip list changes since the vblank request was queued by making sure the window has at least one rectangle while looking inside, preventing oopses .

* drm: Add GEM ("graphics execution manager") to i915 driver.Eric Anholt2008-10-181-4/+249
| | | | | | | | | | | | | | | | GEM allows the creation of persistent buffer objects accessible by the graphics device through new ioctls for managing execution of commands on the device. The userland API is almost entirely driver-specific to ensure that any driver building on this model can easily map the interface to individual driver requirements. GEM is used by the 2d driver for managing its internal state allocations and will be used for pixmap storage to reduce memory consumption and enable zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.

* drm: Rework vblank-wait handling to allow interrupt reduction.Jesse Barnes2008-10-181-5/+15
| | | | | | | | | | | | | | | Previously, drivers supporting vblank interrupt waits would run the interrupt all the time, or all the time that any 3d client was running, preventing the CPU from sleeping for long when the system was otherwise idle. Now, interrupts are disabled any time that no client is waiting on a vblank event. The new method uses vblank counters on the chipsets when the interrupts are turned off, rather than counting interrupts, so that we can continue to present accurate vblank numbers.
