skylake scaler structure definitions. scalers live in crtc_state as they are pipe resources. They can be used either as plane scaler or panel fitter. scaler assigned to either plane (for plane scaling) or crtc (for panel fitting) is saved in scaler_id in plane_state or crtc_state respectively. scaler_id is used instead of scaler pointer in plane or crtc state to avoid updating scaler pointer everytime a new crtc_state is created. v2: -made single copy of min/max values for scalers (Matt) v3: -updated commentary for scaler_id (me) v4: -converted src/dst ranges to #defines, dropped ratios (Matt) Signed-off-by:

Connector states were being allocated in intel_setup_outputs() in loop over all connectors. That meant hot-added connectors would have a NULL state. Since the change to use a struct drm_atomic_state for the legacy modeset, connector states are necessary for the i915 driver to function properly, so that would lead to oopses. v2: Fix test for intel_connector_init() success in lvds and sdvo (PRTS) Signed-off-by:

When looking for viable candidates to shrink, we only want objects that are not pinned. However to do so we performed a double iteration over the vma in the objects, first looking for the pin-count, then looking for allocations. We can do both at once and be slightly more explicit in our validity test. Signed-off-by:

As we never expose context objects directly to userspace, we can forgo allocating a first-class GEM object for them and prefer to use the limited resource of reserved/stolen memory for them. Note this means that their initial contents are undefined. However, a downside of using stolen objects for execlists is that we cannot access the physical address directly (thanks MCH!) which prevents their use. Signed-off-by:

Similar in vain in reducing the number of unrequired spinlocks used for execlist command submission (where the forcewake is required but manually controlled), we know that the IRQ registers are outside of the powerwell and so we can access them directly. Since we now have direct access exported via I915_READ_FW/I915_WRITE_FW, lets put those to use in the irq handlers as well. In the process, reorder the execlist submission to happen as early as possible. v2: Restrict the untraced register mmio to just the GT path (i.e. the hotpath for execlists) Signed-off-by:

Once we have full atomic modeset, these kind of flags should be in a real intel_crtc_state that's tracked properly. In the meantime, make sure we clear out any old flags at the beginning of a transaction so that we don't wind up seeing leftover flags from old transactions that were checked, but never went to the commit step. At the moment, a failed check or prepare could leave stale flags behind that interfere with the next atomic transaction. v2: Just do a memset; the series this patch was originally part of placed additional fields into the structure that shouldn't be cleared, but that's no longer the case.

Switch from our plane update/disable entrypoints to use the full atomic helpers (which generate a top-level atomic transaction) rather than the transitional helpers (which only create/manipulate orphaned plane states independent of a top-level transaction). Various upcoming work (SKL scalers, atomic watermarks, etc.) requires a full atomic transaction to behave properly/cleanly. Last time we tried this, we had to back out the change because we still call the drm_plane vfuncs directly from within our legacy modesetting code. This potentially results in nested atomic transactions, locking collisions, and other failures. To avoid that problem again, we sidestep the issue by calling the transitional helpers directly (rather than through a vfunc) when we're nested inside of other legacy modesetting code. However this does allow legacy SetPlane() ioctl's to process an entire drm_atomic_state transaction, which is important for upcoming patches.

After the removal of DRI1, all access to the rings are through requests and so we can always be sure that there is a request to wait upon to free up available space. The fallback code only existed so that we could quiesce the GPU following unmediated access by DRI1. v2: Rebase Signed-off-by:
-
Chris Wilson authored
When we submit a request to the GPU, we first take the rpm wakelock, and only release it once the GPU has been idle for a small period of time after all requests have been complete. This means that we are sure no new interrupt can arrive whilst we do not hold the rpm wakelock and so can drop the individual get/put around every single request inside execlists. Note: to close one potential issue we should mark the GPU as busy earlier in __i915_add_request. To elaborate: The issue is that we emit the irq signalling sequence before we grab the rpm reference, which means we could miss the resulting interrupt (since that's not set up when suspended). The only bad side effect is a missed interrupt, gt mmio writes automatically wake up the hw itself. But otoh we have an umbrella rpm reference for the entirety of execbuf, as long as that's there we're covered. Signed-off-by:

Recent BSW VBT has a VBT child device size 37 bytes instead of the 33 bytes our code assumes. This means we fail to parse the VBT and thus fail to detect eDP ports properly and just register them as DP ports instead. Fix it up by using the reported child device size from the VBT instead of assuming it matches out struct defintions. The latest spec I have shows that the child device size should be 36 bytes for rev >= 195, however on my BSW the size is actually 37 bytes. And our current struct definition is 33 bytes. Feels like the entire VBT parses would need to be rewritten to handle changes in the layout better, but for now I've decided to do just the bare minimum to get my eDP port back.

This finishes off the dynamic page tables allocations, in the legacy 3 level style that already exists. Most everything has already been setup to this point, the patch finishes off the enabling by setting the appropriate function pointers. In LRC mode, contexts need to know the PDPs when they are populated. With dynamic page table allocations, these PDPs may not exist yet. Check if PDPs have been allocated and use the scratch page if they do not exist yet. Before submission, update the PDPs in the logic ring context as PDPs have been allocated. v2: Update aliasing/true ppgtt allocate/teardown/clear functions for gen 6 & 7. v3: Rebase. v4: Remove BUG() from ppgtt_unbind_vma, but keep checking that either teardown_va_range or clear_range functions exist (Daniel). v5: Similar to gen6, in init, gen8_ppgtt_clear_range call is only needed for aliasing ppgtt. Zombie tracking was originally added for teardown function and is no longer required. v6: Update err_out case in gen8_alloc_va_range (missed from lastest rebase). v7: Rebase after s/page_tables/page_table/. v8: Updated scratch_pt check after scratch flag was removed in previous patch. v9: Note that lrc mode needs to be updated to support init state without any PDP. v10: Unmap correct page_table in gen8_alloc_va_range's error case, clean-up gen8_aliasing_ppgtt_init (remove duplicated map), and initialize PTs during page table allocation. v11: Squashed LRC enabling commit, otherwise LRC mode would be left broken until it was updated to handle the init case without any PDP. v12: Do not overallocate new_pts bitmap, make alloc_gen8_temp_bitmaps static and don't abuse of inline functions.

When we do dynamic page table allocations for gen8, we'll need to have more control over how and when we map page tables, similar to gen6. In particular, DMA mappings for page directories/tables occur at allocation time. This patch adds the functionality and calls it at init, which should have no functional change. The PDPEs are still a special case for now. We'll need a function for that in the future as well. v2: Handle renamed unmap_and_free_page functions. v3: Updated after teardown_va logic was removed. v4: Rebase after s/page_tables/page_table/. v5: No longer allocate all PDPs in GEN8+ systems with less than 4GB of memory, and update populate_lr_context to handle this new case (proper tracking will be added later in the patch series). v6: Assign lrc page directory pointer addresses using a macro.

One important part of this patch is we now write a scratch page directory into any unused PDP descriptors. This matters for 2 reasons, first, we're not allowed to just use 0, or an invalid pointer, and second, we must wipe out any previous contents from the last context. The latter point only matters with full PPGTT. The former point only effect platforms with less than 4GB memory. v2: Updated commit message to point that we must set unused PDPs to the scratch page. v3: Unmap scratch_pd in gen8_ppgtt_free. v4: Initialize scratch_pd.
