Now that we have selftests in place exercising truly huge allocations we will start to hit the 512GB warning, so now seems like a good time to remove this user-triggerable WARN. Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

If we fail to dma-map the object, the most common cause is lack of space inside the SW-IOTLB due to fragmentation. If we recreate the_sg_table using segments of PAGE_SIZE (and single page allocations), we may succeed in remapping the scatterlist. First became a significant problem for the mock selftests after commit 5584f1b1 ("drm/i915: fix i915 running as dom0 under Xen") increased the max_order.

Apparently there are machines out there with Skylake CPU and KabyPoint PCH. Judging from our driver code, there doesn't seem to be any code paths that would do anything different between SunrisePoint and KabyPoint PCHs, so it would seem okay to accept the combo without warnings. Fixes: 22dea0be ("drm/i915: Introduce Kabypoint PCH for Kabylake H/DT.") References: https://lists.freedesktop.org/archives/intel-gfx/2017-February/118611.htmlReported-by:

Commit 920cf419 ("drm/i915: Introduce an internal allocator for disposable private objects") introduced a regression for the kernel running as Xen dom0: when switching to graphics mode a GPU HANG occurred. Reason seems to be a missing adaption similar to that done in commit 7453c549 ("swiotlb: Export swiotlb_max_segment to users") to i915_gem_object_get_pages_internal(). So limit the maximum page order to be used according to the maximum swiotlb segment size instead to the complete swiotlb size.

If the crtc was brought up with audio before the driver loads, then crtc_disable will remove a refcount to audio that doesn't exist before. Fortunately we already set power domains on readout, so we can just add the power domain handling to get_crtc_power_domains, which will update the power domains correctly in all cases. This was found when testing module reload on CI with the crtc enabled, which resulted in the following warn after module reload + modeset: [ 24.197041] ------------[ cut here ]------------ [ 24.197075] WARNING: CPU: 0 PID: 99 at drivers/gpu/drm/i915/intel_runtime_pm.c:1790 intel_display_power_put+0x134/0x140 [i915] [ 24.197076] Use count on domain AUDIO is already zero [ 24.197098] CPU: 0 PID: 99 Comm: kworker/u8:2 Not tainted 4.9.0-CI-Trybot_393+ #1 [ 24.197099] Hardware name: /NUC6i5SYB, BIOS SYSKLi35.86A.0042.2016.0409.1246 04/09/2016 [ 24.197102] Workqueue: events_unbound async_run_entry_fn [ 24.197105] ffffc900003c7688 ffffffff81435b35 ffffc900003c76d8 0000000000000000 [ 24.197107] ffffc900003c76c8 ffffffff8107e4d6 000006fe5dc36f28 ffff88025dc30054 [ 24.197109] ffff88025dc36f28 ffff88025dc30000 ffff88025dc30000 0000000000000015 [ 24.197110] Call Trace: [ 24.197113] [<ffffffff81435b35>] dump_stack+0x67/0x92 [ 24.197116] [<ffffffff8107e4d6>] __warn+0xc6/0xe0 [ 24.197118] [<ffffffff8107e53a>] warn_slowpath_fmt+0x4a/0x50 [ 24.197149] [<ffffffffa039b4b4>] intel_display_power_put+0x134/0x140 [i915] [ 24.197187] [<ffffffffa04217dd>] intel_disable_ddi+0x4d/0x80 [i915] [ 24.197223] [<ffffffffa03f388f>] intel_encoders_disable.isra.74+0x7f/0x90 [i915] [ 24.197257] [<ffffffffa03f6c05>] haswell_crtc_disable+0x55/0x170 [i915] [ 24.197292] [<ffffffffa03fec88>] intel_atomic_commit_tail+0x108/0xfd0 [i915] [ 24.197295] [<ffffffff810d47c6>] ? __lock_is_held+0x66/0x90 [ 24.197330] [<ffffffffa03fff79>] intel_atomic_commit+0x429/0x560 [i915] [ 24.197332] [<ffffffff81570186>] ?drm_atomic_add_affected_connectors+0x56/0xf0 [ 24.197334] [<ffffffff8156f726>] drm_atomic_commit+0x46/0x50 [ 24.197336] [<ffffffff81553f87>] restore_fbdev_mode+0x147/0x270 [ 24.197337] [<ffffffff81555bee>] drm_fb_helper_restore_fbdev_mode_unlocked+0x2e/0x70 [ 24.197339] [<ffffffff81555aa8>] drm_fb_helper_set_par+0x28/0x50 [ 24.197374] [<ffffffffa041c7d3>] intel_fbdev_set_par+0x13/0x70 [i915] [ 24.197376] [<ffffffff8149e07a>] fbcon_init+0x57a/0x600 [ 24.197379] [<ffffffff81514b71>] visual_init+0xd1/0x130 [ 24.197381] [<ffffffff8151603c>] do_bind_con_driver+0x1bc/0x3a0 [ 24.197384] [<ffffffff81516521>] do_take_over_console+0x111/0x180 [ 24.197386] [<ffffffff8149e152>] do_fbcon_takeover+0x52/0xb0 [ 24.197387] [<ffffffff814a12c3>] fbcon_event_notify+0x723/0x850 [ 24.197390] [<ffffffff810a4830>] ?__blocking_notifier_call_chain+0x30/0x70 [ 24.197392] [<ffffffff810a44a4>] notifier_call_chain+0x34/0xa0 [ 24.197394] [<ffffffff810a4848>] __blocking_notifier_call_chain+0x48/0x70 [ 24.197397] [<ffffffff810a4881>] blocking_notifier_call_chain+0x11/0x20 [ 24.197398] [<ffffffff814a4556>] fb_notifier_call_chain+0x16/0x20 [ 24.197400] [<ffffffff814a678c>] register_framebuffer+0x24c/0x330 [ 24.197402] [<ffffffff815558d9>] drm_fb_helper_initial_config+0x219/0x3c0 [ 24.197436] [<ffffffffa041d373>] intel_fbdev_initial_config+0x13/0x30 [i915] [ 24.197438] [<ffffffff810a5d44>] async_run_entry_fn+0x34/0x140 [ 24.197440] [<ffffffff8109c26c>] process_one_work+0x1ec/0x6b0 [ 24.197442] [<ffffffff8109c1e6>] ? process_one_work+0x166/0x6b0 [ 24.197445] [<ffffffff8109c779>] worker_thread+0x49/0x490 [ 24.197447] [<ffffffff8109c730>] ? process_one_work+0x6b0/0x6b0 [ 24.197448] [<ffffffff810a2a9b>] kthread+0xeb/0x110 [ 24.197451] [<ffffffff810a29b0>] ? kthread_park+0x60/0x60 [ 24.197453] [<ffffffff818241a7>] ret_from_fork+0x27/0x40 [ 24.197476] ---[ end trace bda64b683b8e8162 ]--- Signed-off-by:

On a non-llc system, the objects are created with .cache_level = CACHE_NONE and so the transition to uncached for scanout is a no-op. However, if the object was never written to, it will still be in the CPU domain (having been zeroed out by shmemfs). Those cachelines need to be flushed prior to display.

Chris Wilson authored
The conversion of stolen to use phys_addr_t (from essentially u32) sparked an interesting discussion. We treat stolen memory as only accessible from the GPU (the DMA device) - an attempt to use it from the CPU will generate a MCE on gen6 onwards, although it is in theory a physical address that can be dereferenced from the CPU as demonstrated by earlier generations. As such, using phys_addr_t has the wrong connotations and as we pass the address into the DMA device via dma_addr_t (through the scatterlists used to program the GTT entries), we should treat it as dma_addr_t throughout.

For a virtualized GPU, the host maintains the forcewake state on the real device. As we don't control forcewake ourselves, we can simply set force_wake_get() and force_wake_put() to be no-ops. By setting the vfuncs, we adjust both the manual control of forcewake and around the mmio accessors (making our vgpu specific mmio routines redundant and to be removed in the next patch).

The size computations done in the ioctl function use an integer. If userspace submits a request with req->cmd_nr or req->cmd_buf_nr set to INT_MAX, the integer computations overflow later, leading to potential (kernel) memory corruption. Prevent this issue by enforcing a limit on the number of submitted commands, so that we have enough headroom later for the size computations. Note that this change has no impact on the currently available users in userspace, like e.g. libdrm/exynos. While at it, also make a comment about the size computation more detailed. Signed-off-by:

We were trying to print an error message if we timed out here, but the loop actually ends with "tries" set to UINT_MAX and not zero. Fix this by changing from tries-- to --tries. A for loop would actually be the most natural way to do this. My fix means we only loop 99 times instead of 100 but that's probably ok.

This patch replaces specific atomic commit function with atomic helper commit one. For this, it removes existing atomic commit function and relevant code specific to Exynos DRM and makes atomic helper commit to be used instead. Below are changes for the use of atomic helper commit: - add atomic_commit_tail callback specific to Exynos DRM . default implemention of atomic helper doesn't mesh well with runtime PM so the device driver which supports runtime PM should call drm_atomic_helper_commit_modeset_enables function prior to drm_atomic_helper_commit_planes function call. atomic_commit_tail callback implements this call ordering. - allow plane commit only in case that CRTC device is enabled. . for this, it calls atomic_helper_commit_planes function with DRM_PLANE_COMMIT_ACTIVE_ONLY flag in atomic_commit_tail callback.

Before applying the patch, used the of_get_videomode function to parse the display-timings in the panel which is the child driver of dsi in the devicetree. this is wrong. So removed the of_get_videomode and fixed to get videomode struct through mode_set callback function. Signed-off-by:

This allows the use of more than 3 ports/pipes/whatever without tricks, even if the register offsets are not evenly spaced. There's the risk of out of bounds access if we're not careful; currently that would "just" lead to the wrong register offset being used. It might be possible to add build bug ons for build time constant indexing. We already have ports defined up to E, not sure if we might have bugs related to them and the current _PORT3() macro. text data bss dec hex filename 1239868 46199 4096 1290163 13afb3 drivers/gpu/drm/i915/i915.ko 1238828 46199 4096 1289123 13aba3 drivers/gpu/drm/i915/i915.ko Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Tvrtko Ursulin <tursulin@ursulin.net> Reviewed-by:

Move the invariant parts of context desc setup from execlist init to context creation. This is advantageous when we need to create different templates based on the context parametrization, ie. for svm capable contexts. v2: s/create/default, remove engine->ctx_desc_template Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:
