The throttle-ioctl never touches the struct_mutex. It does, however, as part of its ABI report whether the hardware is terminally wedged. For that purposes, it only has to report the current state and not incur the cost of checking/waiting every invocation, as we do not have to wait for a reset before waiting on a request to ensure completion (that is baked into the wait request implementation).

In forthcoming patches, we want to be able to dynamically allocate the wait_queue_t used whilst awaiting. This is more convenient if we extend the i915_sw_fence_await_sw_fence() to perform the allocation for us if we pass in a gfp mask as an alternative than a preallocated struct. Signed-off-by:

We will need to wait on DMA completion (as signaled via struct fence) before executing our i915_gem_request. Therefore we want to expose a method for adding the await on the fence itself to the request. v2: Add a comment detailing a failure to handle a signal-on-any fence-array. v3: Pretend that magic numbers don't exist.

We are not allowed to touch the GTT entries underneath an atomic section, as they take a rpm wakelock (which is illegal from atomic context) and in the near future acquiring the DMA address for a page within an object may sleep for an allocation. This makes the current shortcircuit in relocation_iomap() for performing a second relocation on an adjacent page illegal, and we need to release the atomic iomapping, lookup the DMA, insert it into the GTT before reentering the atomic iomap section. As it happens, this is precisely what we do on if we are using an iomapping over the full object and not just a single page and by removing the shortcut, we do the right thing.

This macro's name is a bit misleading; it doesn't actually iterate over all planes since it omits the cursor plane. Its only uses are in gen9 code which is using it to iterate over the universal planes (which we treat as primary+sprites); in these cases the legacy cursor registers are programmed independently if necessary. The macro's iterator value (0 for primary plane, spritenum+1 for each secondary plane) also isn't meaningful outside the gen9 context where the hardware considers them to all be "universal" planes that follow this numbering. This is just a renaming/clarification patch with no functional change. However it will make the subsequent patches more clear. Signed-off-by:

Use struct bxt_ddi_phy_info to hold information of where the Rcomp resistor is located, instead of hard coding it in the init sequence. Note that this moves the enabling of the phy with the Rcomp resistor out of the power well enable code. That should be safe since bxt_ddi_phy_init() is called while the power domains lock is held, and that is the only way that function gets called, so there is no possibility of a concurrent phy enable caused by a power domain get call. v2: Replace comment about lock with lockdep_assert_held() (Imre) Signed-off-by:

Pass the framebuffer size in .16 fixed point coordinates to drm_rect_rotate() since that's what the source coordinates are as well at this stage. We used to do this part of the computation in integer coordinates, but that got changed when moving the computation to happen in the check phase of the operation. Unfortunately I forgot to shift up the fb width and height appropriately. With the bogus size we ended up with some negative fb offset, which when added to the vma offset caused out scanout to start at an offset earlier than we inteded. Eg. when testing on my SKL I saw a row of incorrect tiles at the top of my screen.

On my APL the LSPCON firmware resumes in PCON mode as opposed to the expected LS mode. It also appears to be in a state where AUX DPCD reads will succeed but return garbage recovering only after a few hundreds of milliseconds. After the recovery time DPCD reads will result in the correct values and things will continue to work. If I2C over AUX is attempted during this recovery time (implying an AUX write transaction) the firmware won't recover and will stay in this broken state. As a workaround check if the firmware is in PCON state after resume and if so wait until the correct DPCD values are returned. For this we compare the branch descriptor with the one we cached during init time. If the firmware was in the LS state, we skip the w/a and continue as before. v2: - Use the DP descriptor value cached in intel_dp. (Jani) - Get to intel_dp using container_of(), instead of a cached ptr. (Shashank) - Use usleep_range() instead of msleep().
