drm/imx: ipuv3-plane: fix frame rate regression on non-plus i.MX6Q Fix a regression introduced by 70e8a0c71e9 ("drm/imx: ipuv3-plane: add function to query atomic update status") that halves the frame rate on non-plus i.MX6Q, because the pending check always returns "pending" even if an update is actually applied.

2019-05-30drm/i915: add in-kernel blitter clientMatthew Auld9-0/+702
The plan is to use the blitter engine for async object clearing when using local memory, but before we can move the worker to get_pages() we have to first tame some more of our struct_mutex usage. With this in mind we should be able to upstream the object clearing as some selftests, which should serve as a guinea pig for the ongoing locking rework and upcoming async get_pages() framework.

Pull documentation fixes from Jonathan Corbet: "The Sphinx 2.0 release contained a few incompatible API changes that broke our extensions and, thus, the documentation build in general. Who knew that those deprecation warnings it was outputting actually meant we should change something? This set of fixes makes the build work again with Sphinx 2.0 and eliminates the warnings for 1.8. As part of that, we also need a few fixes to the docs for places where the new Sphinx is more strict. It is a bit late in the cycle for this kind of change, but it does fix problems that people are experiencing now. There has been some talk of raising the minimum version of Sphinx we support. I don't want to do that abruptly, though, so these changes add some glue to continue to support versions back to 1.3. We will be adding some infrastructure soon to nudge users of old versions forward, with the idea of maybe increasing our minimum version (and removing this glue) sometime in the future" * tag 'docs-5.2-fixes2' of git://git.lwn.net/linux: drm/i915: Maintain consistent documentation subsection ordering scripts/sphinx-pre-install: make it handle Sphinx versions docs: Fix conf.py for Sphinx 2.0 docs: fix multiple doc build warnings in enumeration.rst lib/list_sort: fix kerneldoc build error docs: fix numaperf.rst and add it to the doc tree doc: Cope with the deprecation of AutoReporter doc: Cope with Sphinx logging deprecations

2019-05-29drm/i915/gtt: Avoid overflowing the WC stashChris Wilson1-4/+7
An interesting issue cropped with making the pagetables be allocated and freed concurrently (i.e. removing their grandeous struct_mutex guard) was that we would overflow the page stash. This happens when we have multiple allocators grabbing WC pages such that we fill the vm's local page stash and then when we free another page, the page stash is already full and we overflow. The fix is quite simple: to check for a full page stash before adding another. This results in us keeping a vm local page stash around for much longer, which is both a blessing and a curse.

2019-05-29Revert "drm/i915: Expand subslice mask"Jani Nikula11-198/+114
This reverts commit 1ac159e23c2c ("drm/i915: Expand subslice mask"), which kills ICL due to GEM_BUG_ON() sanity checks before CI even gets a chance to do anything. The commit exposes an issue in commit 1e40d4aea57b ("drm/i915/cnl: Implement WaProgramMgsrForCorrectSliceSpecificMmioReads"), which will also need to be addressed. There's a proposed fix [1], but considering the seeming uncertainty with the fix as well as the size of the regressing commit (in this context, the one that actually brings down ICL), this warrants a revert to get ICL working, and gives us time to get all of this right without rushing. Even if this means shooting the messenger. <3>[ 9.426327] intel_sseu_get_subslices:46 GEM_BUG_ON(slice >= sseu->max_slices) <4>[ 9.426355] ------------[ cut here ]------------ <2>[ 9.426357] kernel BUG at drivers/gpu/drm/i915/gt/intel_sseu.c:46! <4>[ 9.426371] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI <4>[ 9.426377] CPU: 1 PID: 364 Comm: systemd-udevd Not tainted 5.2.0-rc2-CI-CI_DRM_6159+ #1 <4>[ 9.426385] Hardware name: Intel Corporation Ice Lake Client Platform/IceLake U DDR4 SODIMM PD RVP TLC, BIOS ICLSFWR1.R00.3183.A00.1905020411 05/02/2019 <4>[ 9.426444] RIP: 0010:intel_sseu_get_subslices+0x8a/0xe0 [i915] <4>[ 9.426452] Code: d5 76 b7 e0 48 8b 35 9d 24 21 00 49 c7 c0 07 f0 72 a0 b9 2e 00 00 00 48 c7 c2 00 8e 6d a0 48 c7 c7 a5 14 5b a0 e8 36 3c be e0 <0f> 0b 48 c7 c1 80 d5 6f a0 ba 30 00 00 00 48 c7 c6 00 8e 6d a0 48 <4>[ 9.426468] RSP: 0018:ffffc9000037b9c8 EFLAGS: 00010282 <4>[ 9.426475] RAX: 000000000000000f RBX: 0000000000000000 RCX: 0000000000000000 <4>[ 9.426482] RDX: 0000000000000001 RSI: 0000000000000008 RDI: ffff88849e346f98 <4>[ 9.426490] RBP: ffff88848a200000 R08: 0000000000000004 R09: ffff88849d50b000 <4>[ 9.426497] R10: 0000000000000000 R11: ffff88849e346f98 R12: ffff88848a209e78 <4>[ 9.426505] R13: 0000000003000000 R14: ffff88848a20b1a8 R15: 0000000000000000 <4>[ 9.426513] FS: 00007f73d5ae8680(0000) GS:ffff88849fc80000(0000) knlGS:0000000000000000 <4>[ 9.426521] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 <4>[ 9.426527] CR2: 0000561417b01260 CR3: 0000000494764003 CR4: 0000000000760ee0 <4>[ 9.426535] PKRU: 55555554 <4>[ 9.426538] Call Trace: <4>[ 9.426585] wa_init_mcr+0xd5/0x110 [i915] <4>[ 9.426597] ?

In intel_wakeref_auto, we use refcount_inc_not_zero to detect the first use and initialise the timer. On doing so, we have to avoid using refcount_inc on that zero count as the debug code flags that as an error: refcount_t: increment on 0; use-after-free. Rearrange the code so that if we know the count is 0 and we are initialising, we explicitly set it to 1.
