This will be useful later on. Also move the functions around to not need forward declarations in subsequent patches. No functional changes.

There is no requirement for doing the PCODE request polling atomically, so do that only for a short time switching to sleeping poll afterwards. The specification requires a 150usec timeout for the change notification, so let's use that for the atomic poll. Do the extra 2ms poll - needed as a workaround on BXT/GLK - in sleeping mode. v2: - rebase on v2 of patchset dropping the sandybridge_pcode_read/write refactoring (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Currently we see sporadic timeouts during CDCLK changing both on BXT and GLK as reported by the Bugzilla: ticket. It's easy to reproduce this by changing the frequency in a tight loop after blanking the display. The upper bound for the completion time is 800us based on my tests, so increase it from the current 500us to 2ms; with that I couldn't trigger the problem either on BXT or GLK. Note that timeouts happened during both the change notification and the voltage level setting PCODE request. (For the latter one BSpec doesn't require us to wait for completion before further HW programming.) This issue is similar to commit 2c7d0602 ("drm/i915/gen9: Fix PCODE polling during CDCLK change notification") but there the PCODE request does complete (as shown by the mbox busy flag), only the reply we get from PCODE indicates a failure. So there we keep resending the request until a success reply, here we just have to increase the timeout for the one PCODE request we send. v2: - s/snb_pcode_request/sandybridge_pcode_write_timeout/ (Ville) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: <stable@vger.kernel.org> # v4.4+ Acked-by: Chris Wilson <chris@chris-wilson.co.uk> (v1) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103326Reviewed-by:

In case of GuC initialization failure we may continue with driver load, but we wrongly assume that GuC is fully functional. This leads to the BUG as we attempt to access non-existing log vma.

We're freeing GuC error log in uc_fini_hw() that matches corresponding uc_init_hw() but we missed the point that this log object is copied on error path and in case of failure in uc_init_hw() we will leak this object as uc_fini_hw() is never called.

Commit e2b763ca ("drm/i915: Remove bitmap tracking for used-pdpes") believed that because it did not insert its freshly allocated page directory into the pd tree, it was safe from the shrinker. I failed to heed the lesson learnt from commit dd19674b ("drm/i915: Remove bitmap tracking for used-ptes") that we need to pin all the levels in the tree before hitting the shrinker or else the shrinker may free an upper layer as we proceed to allocate the tree. Thus leaving dangling pointers everywhere and a GPF should we hit direct reclaim at just the wrong moment. CPU: 0 PID: 7374 Comm: chromium Tainted: P O 4.14.13-1-ARCH #1 Hardware name: Apple Inc.

This patch clears a single bit. The bit is 0 by default but expected not to be set. Explicitly clearing the bit in this patch is intended to indicate some thinking has occurred, and that we want this bit cleared and we are not just excepting the default value. We also stop setting GFX_RUN_LIST_ENABLE, which is correct since that bit is gone. v2 (from Paulo): fix indentation. v3: Changed GEN check to >= 11.

This is a precautionary measure as I have no evidence to suggest we've hit a bug here (I was hoping this might explain gdg's odd behaviour, but alas), but given that we have a function to flush the ggtt writes it seems prudent to use it prior to changing the fence register. Due to the intrinsic nature of the GTT often operating as an independent mmio path, we should not just rely on the write to the fence acting as a full flush for GTT writes. Signed-off-by:

guc_log_relay_file_create will return -EEXIST if we invoke relay_late_setup_files multiple times as part of i915_guc_log_control. However this is to be not cosidered as fail and need to return 0. This was mistakenly introduced in the below commit. Fix it. Fixes: 70deeadd "drm/i915/guc: Fix lockdep due to log relay channel handling under struct_mutex" Signed-off-by:

Previously, we relied on only running the hangcheck while somebody was waiting on the GPU, in order to minimise the amount of time hangcheck had to run. (If nobody was watching the GPU, nobody would notice if the GPU wasn't responding -- eventually somebody would care and so kick hangcheck into action.) However, this falls apart from around commit 4680816b ("drm/i915: Wait first for submission, before waiting for request completion"), as not all waiters declare themselves to hangcheck and so we could switch off hangcheck and miss GPU hangs even when waiting under the struct_mutex. If we enable hangcheck from the first request submission, and let it run until the GPU is idle again, we forgo all the complexity involved with only enabling around waiters. We just have to remember to be careful that we do not declare a GPU hang when idly waiting for the next request to be come ready, as we will run hangcheck continuously even when the engines are stalled waiting for external events. This should be true already as we should only be tracking requests submitted to hardware for execution as an indicator that the engine is busy.

On CNP boards that are using DDI F, bit 25 (SDE_PORTE_HOTPLUG_SPT) is representing the Digital Port F hotplug line when the Digital Port F hotplug detect input is enabled. v2: Reuse all existent structure instead of adding a new HPD_PORT_F pointing to pin of port E. v3: Use IS_CNL_WITH_PORT_F so we can start upstreaming this right now. If that SKU ever get a proper name we come back and update it. v4: Rebase on top of digital connected port using encoder instead of port. v5: Moved IS_CNL_WITH_PORT_F definition to the PCI IDs patch.

Let's try to simplify this mapping to hpd_pin -> bit instead using port. So for CNL with port F where we have this port using hdp_pin and bits of other ports we don't need to duplicated the mapping. But for now this is only a re-org with no functional change expected. v2: Add missing lines and nuke @port reference from code documentation.

Since when it got introduced with commit '555e38d2 ("drm/i915/cnl: DDI - PLL mapping")' the support for Port F was wrong, because Port F bits are far from bits used for A to E. Since Port F is not used so far we don't need to propagate Fixes back there. v2: Reuse _SHIFT definition to avoid complicated duplication (DK).

On some Cannonlake SKUs we have a dedicated Aux for port F, that is only the full split between port A and port E.

The only difference is that this SKUs has the full Port A/E split named as Port F. But since SKUs differences don't matter on the platform definition group and ids, let's merge all off them together. v2: Really include the PCI IDs to the picidlist[]; v3: Add the PCI Id for another SKU (Anusha). v4: Update IDs, really include to pciidlists again. v5: Unify all GT2 IDs. v6: Unify in a way that we don't break early-quirks.c v7: Remove GT reference since it doesn't matter here (Paulo) Also move IS_CNL_WITH_PORT_F macro to this patch to make it easier for review this part and also to get used sooner. v8: Rebased on top of commit 5db47e37 ("Revert "drm/i915: mark all device info struct with __initconst"") Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by:Anusha Srivatsa <anusha.srivatsa@intel.com> Signed-off-by:

While running the kms_plane clipping test I noticed a similar problem to the one described in Display WA #1175. In this case, similarly for planes other than the cursor, with 1 or 3 pixels visible from the left edge of the screen to the end of the plane and an odd plane X offset used for clipping causes the same kind of underflow and display corruption as described for WA #1175. Fix this in a similar way as that WA rejecting planes ending <4 pixels from the left screen edge. v2: - Rebase on v2 of patch 1/1. Testcase: igt/kms_plane/plane-clipping-pipe-*-planes Signed-off-by:

As described in the WA on GLK and CNL planes on the right edge of the screen that have less than 4 pixels visible from the beginning of the plane to the edge of the screen can cause FIFO underflow and display corruption. On GLK/CNL I could trigger the problem only if the plane was at the same time also aligned to the top edge of the screen (after clipping) and there were exactly 2 pixels visible from the start of the plane to the right edge of the screen (so couldn't trigger it with 1 or 3 pixels visible). Nevertheless, to be sure, I also applied the WA for these cases. I also couldn't see any problem with the cursor plane and later Art confirmed that it's not affected, so the WA is applied only for the other plane types. v2: - Use -ERANGE instead of -EINVAL.

If the table result is out of bounds on the array map there is something really wrong with VBT pin so we don't return that vbt_pin, but only return 0 instead. This basically reverts commit 'a8e6f388 ("drm/i915/cnp: Ignore VBT request for know invalid DDC pin.")' Also this properly fixes commit 9c3b2689 ("drm/i915/cnl: Map VBT DDC Pin to BSpec DDC Pin.") v2: Do in a way that we don't break other platforms. (Jani) v3: Keep debug message (Jani) v4: Don't mess with 0 mapping was noticed by Jani and addressed with a simple solution suggested by Lucas that makes this even simpler.

CTX_CONTEXT_CONTROL (CTX_SR_CTL) operates as a masked register and so will only apply the bits that are selected by the upper half. In the case of selectively enabling sr inhibit, this may mean the context keeps the current setting (so forgetting to save the context later, eventually leading to a very upset GPU!).
