Coffee Lake is a Intel
® Processor containing Intel® HD Graphics following Kabylake. It is Gen9 graphics based platform on top of CNP PCH. Let's start by adding the platform definition based on previous platforms but yet as preliminary_hw_support. On following patches we will start adding PCI IDs and the platform specific changes. v2: Also add BS2 ring that is present on GT3. As on KBL, according spec: "GT3 also has additional media blocks with second instance of VEBox and VDBox each", i.e. BSD2 ring in our case. Noticed when reviewing PCI ID patches. v3: CFL_PLATFORM instead for CFL_FEATURES because it contains Platform information and no new features when compared to BDW_FEATURES definition. v4: Rebased on top of Cannonlake patches.

Originally we would enable and disable the breadcrumb interrupt immediately on demand. This was slow enough to have a large impact (>30%) on tasks that hopped between engines. However, by using a shadow to keep the irq alive for an extra interrupt (see commit 67b807a8 ("drm/i915: Delay disabling the user interrupt for breadcrumbs")) and by recently reducing the cost in adding ourselves to the signal tree, we no longer need to spin-request during await_request to avoid delays in throughput tests. Without the earlier patches to stop the wakeup when signaling if the irq was already active, we saw no improvement in execbuf overhead (and corresponding contention in other clients) despite the removal of the spinner in a simple test like glxgears. This means there will be scenarios where now we spend longer enabling the interrupt than we would have spent spinning, but these are not likely to have as noticeable an impact as the high frequency test cases (where there should not be any regression). Ulterior motive: generalising the engine->sync_to to handle different types of semaphores and non-semaphores. Signed-off-by:

The important condition that we need to check after enabling the interrupt for signaling is whether the request completed in the process (and so we missed that interrupt). A large cost in enabling the signaling (rather than waiters) is in waking up the auxiliary signaling thread, but we only need to do so to catch that missed interrupt. If we know we didn't miss any interrupts (because we didn't arm the interrupt) then we can skip waking the auxiliary thread. Signed-off-by:

skl_check_plane_surface() already rotates the clipped plane source coordinates to match the scanout direction because that's the way the GTT mapping is set up. Thus we no longer need to rotate the coordinates in the watermark code. For cursors we use the non-clipped coordinates which are not rotated appropriately, but that doesn't actually matter since cursors don't even support 90/270 degree rotation. v2: Resolve conflicts from SKL+ wm rework Cc: stable@vger.kernel.org Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Fixes: b63a16f6 ("drm/i915: Compute display surface offset in the plane check hook for SKL+") Signed-off-by:

Starting from commit b63a16f6 ("drm/i915: Compute display surface offset in the plane check hook for SKL+") we've already rotated the src coordinates by 270 degrees by the time we check if a scaler is needed or not, so we must not account for the rotation a second time. Previously we did these steps in the opposite order and hence the scaler check had to deal with rotation itself. The double rotation handling causes us to enable a scaler pretty much every time 90/270 degree plane rotation is requested, leading to fuzzier fonts and whatnot. v2: s/unsigned/unsigned int/ to appease checkpatch v3: s/DRM_ROTATE_0/DRM_MODE_ROTATE_0/ Cc: stable@vger.kernel.org Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reported-by:

The number of compressed segments has been available ever since FBC2 was introduced in g4x, it just moved from the STATUS register into STATUS2 on IVB. For FBC1 if we really wanted the number of compressed segments we'd have to trawl through the tags, but in this case since the code just uses the number of compressed segments as an indicator whether compression has occurred we can just check the state of the COMPRESSING and COMPRESSED bits. IIRC the hardware will try to periodically recompress all uncompressed lines even if they haven't changed and the COMPRESSED bit will be cleared while the compressor is running, so just checking the COMPRESSED bit might not give us the right answer. Hence it seems better to check for both COMPRESSED and COMPRESSING as that should tell us that the compressor is at least trying to do something. While at it move the IVB+ register define to the right place, unify the naming convention of the compressed segment count masks, and fix up the mask for g4x. v2: s/ILK_DPFC_STATUS2/IVB_FBC_STATUS2/ (Paulo) Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Gabriel Krisman Bertazi <krisman@collabora.co.uk> Signed-off-by:

The scanline counter is bonkers on VLV/CHV DSI. The scanline counter increment is not lined up with the start of vblank like it is on every other platform and output type. This causes problems for both the vblank timestamping and atomic update vblank evasion. On my FFRD8 machine at least, the scanline counter increment happens about 1/3 of a scanline ahead of the start of vblank (which is where all register latching happens still). That means we can't trust the scanline counter to tell us whether we're in vblank or not while we're on that particular line. In order to keep vblank timestamping in working condition when called from the vblank irq, we'll leave scanline_offset at one, which means that the entire line containing the start of vblank is considered to be inside the vblank. For the vblank evasion we'll need to consider that entire line to be bad, since we can't tell whether the registers already got latched or not. And we can't actually use the start of vblank interrupt to get us past that line as the interrupt would fire too soon, and then we'd up waiting for the next start of vblank instead. One way around that would using the frame start interrupt instead since that wouldn't fire until the next scanline, but that would require some bigger changes in the interrupt code. So for simplicity we'll just poll until we get past the bad line. v2: Adjust the comments a bit Cc: stable@vger.kernel.org Cc: Jonas Aaberg <cja@gmx.net> Tested-by:

RAWCLK_FREQ register has changed for platforms with CNP+. [29:26] This field provides the denominator for the fractional part of the microsecond counter divider. The numerator is fixed at 1. Program this field to the denominator of the fractional portion of reference frequency minus one. If the fraction is 0, program to 0. 0100b = Fraction .2 MHz = Fraction 1/5. 0000b = Fraction .0 MHz. [25:16] This field provides the integer part of the microsecond counter divider. Program this field to the integer portion of the reference frequenct minus one. Also this register tells us that proper raw clock should be read from SFUSE_STRAP and programmed to this register.
