drm/i915: preliminary context support Very basic code for context setup/destruction in the driver. Adds the file i915_gem_context.c This file implements HW context support. On gen5+ a HW context consists of an opaque GPU object which is referenced at times of context saves and restores. With RC6 enabled, the context is also referenced as the GPU enters and exists from RC6 (GPU has it's own internal power context, except on gen5). Though something like a context does exist for the media ring, the code only supports contexts for the render ring. In software, there is a distinction between contexts created by the user, and the default HW context. The default HW context is used by GPU clients that do not request setup of their own hardware context. The default context's state is never restored to help prevent programming errors. This would happen if a client ran and piggy-backed off another clients GPU state. The default context only exists to give the GPU some offset to load as the current to invoke a save of the context we actually care about. In fact, the code could likely be constructed, albeit in a more complicated fashion, to never use the default context, though that limits the driver's ability to swap out, and/or destroy other contexts. All other contexts are created as a request by the GPU client. These contexts store GPU state, and thus allow GPU clients to not re-emit state (and potentially query certain state) at any time. The kernel driver makes certain that the appropriate commands are inserted. There are 4 entry points into the contexts, init, fini, open, close. The names are self-explanatory except that init can be called during reset, and also during pm thaw/resume. As we expect our context to be preserved across these events, we do not reinitialize in this case. As Adam Jackson pointed out, The cutoff of 1MB where a HW context is considered too big is arbitrary. The reason for this is even though context sizes are increasing with every generation, they have yet to eclipse even 32k. If we somehow read back way more than that, it probably means BIOS has done something strange, or we're running on a platform that wasn't designed for this. v2: rename load/unload to init/fini (daniel) remove ILK support for get_size() (indirectly daniel) add HAS_HW_CONTEXTS macro to clarify supported platforms (daniel) added comments (Ben) Signed-off-by: Ben Widawsky <ben@bwidawsk.net>

drm/i915: rc6 in sysfs Merge rc6 information into the power group for our device. Until now the i915 driver has not had any sysfs entries (aside from the connector stuff enabled by drm core). Since it seems like we're likely to have more in the future I created a new file for sysfs stubs, as well as the rc6 sysfs functions which don't really belong elsewhere (perhaps i915_suspend, but most of the stuff is in intel_display,c). displays rc6 modes enabled (as a hex mask): cat /sys/class/drm/card0/power/rc6_enable displays #ms GPU has been in rc6 since boot: cat /sys/class/drm/card0/power/rc6_residency_ms displays #ms GPU has been in deep rc6 since boot: cat /sys/class/drm/card0/power/rc6p_residency_ms displays #ms GPU has been in deepest rc6 since boot: cat /sys/class/drm/card0/power/rc6pp_residency_ms Important note: I've seen on SNB that even when RC6 is *not* enabled the rc6 register seems to have a random value in it. I can only guess at the reason reason for this. Those writing tools that utilize this value need to be careful and probably want to scrutinize the value very carefully. v2: use common rc6 residency units to milliseconds for the other RC6 types v3: don't create sysfs files for GEN <= 5 add a rc6_enable to show a mask of enabled rc6 types use unmerge instead of remove for sysfs group squash intel_enable_rc6() extraction into this patch v4: rename sysfs files (Chris) CC: Chris Wilson <chris@chris-wilson.co.uk> CC: Daniel Vetter <daniel.vetter@ffwll.ch>f CC: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Ben Widawsky <benjamin.widawsky@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> [danvet: squash in the 64bit division fix by Chris Wilson.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

drm/i915: add SNB and IVB video sprite support v6 The video sprites support various video surface formats natively and can handle scaling as well. So add support for them using the new DRM core sprite support functions. v2: use drm specific fourcc header and defines v3: address Daniel's comments: - don't take struct mutex around register access (only needed for regs in the GT power well) - don't hold struct mutex across vblank waits - fix up update_plane API (pass obj instead of GTT offset) - add interlaced defines for sprite regs - drop unnecessary 'reg' variables - comment double buffered reg flushing Also fix w/h confusion when writing the scaling reg. v4: more fixes, address more comments from Daniel, and include Hai's fix - prevent divide by zero in scaling calculation (Hai Lan) - update to Ville's new DRM_FORMAT_* types - fix sprite watermark handling (calc based on CRTC size, separate from normal display wm) - remove private refcounts now that the fb cleanups handles things v5: add linear surface support v6: remove color key clearing & setting from update_plane For this version, I tested DPMS since it came up in the last review; DPMS off/on works ok when a video player is working under X, but for power saving we'll probably want to do something smarter. I'll leave that for a separate patch on top. Likewise with the refcounting/fb layer handling, which are really separate cleanups.

i915: add dmabuf/prime buffer sharing support. This adds handle->fd and fd->handle support to i915, this is to allow for offloading of rendering in one direction and outputs in the other. v2 from Daniel Vetter: - fixup conflicts with the prepare/finish gtt prep work. - implement ppgtt binding support. Note that we have squat i-g-t testcoverage for any of the lifetime and access rules dma_buf/prime support brings along. And there are quite a few intricate situations here. Also note that the integration with the existing code is a bit hackish, especially around get_gtt_pages and put_gtt_pages. It imo would be easier with the prep code from Chris Wilson's unbound series, but that is for 3.6. Also note that I didn't bother to put the new prepare/finish gtt hooks to good use by moving the dma_buf_map/unmap_attachment calls in there (like we've originally planned for). Last but not least this patch is only compile-tested, but I've changed very little compared to Dave Airlie's version. So there's a decent chance v2 on drm-next works as well as v1 on 3.4-rc. v3: Right when I've hit sent I've noticed that I've screwed up one obj->sg_list (for dmar support) and obj->sg_table (for prime support) disdinction. We should be able to merge these 2 paths, but that's material for another patch. v4: fix the error reporting bugs pointed out by ickle. v5: fix another error, and stop non-gtt mmaps on shared objects stop pread/pwrite on imported objects, add fake kmap Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
