2020-09-30drm/i915: Break up error capture compression loops with cond_resched()Chris Wilson1-0/+3
As the error capture will compress user buffers as directed to by the user, it can take an arbitrary amount of time and space. Break up the compression loops with a call to cond_resched(), that will allow other processes to schedule (avoiding the soft lockups) and also serve as a warning should we try to make this loop atomic in the future.

2020-09-30drm/i915/gt: Clear the buffer pool age before useChris Wilson1-0/+2
If we create a new node, it is possible for the slab allocator to return us a recently freed node. If that node was just retired, it will retain the current jiffy as its node->age. There is then a miniscule window, where as that node is retired, it will appear on the free list with an incorrect age and be eligible for reuse by one thread, and then by a second thread as the correct node->age is written.

2020-09-30drm/i915/gem: Avoid implicit vmap for highmem on x86-32Chris Wilson1-2/+24
On 32b, highmem using a finite set of indirect PTE (i.e. vmap) to provide virtual mappings of the high pages. As these are finite, map_new_virtual() must wait for some other kmap() to finish when it runs out. If we map a large number of objects, there is no method for it to tell us to release the mappings, and we deadlock. However, if we make an explicit vmap of the page, that uses a larger vmalloc arena, and also has the ability to tell us to release unwanted mappings. Most importantly, it will fail and propagate an error instead of waiting forever.

[Why] Currently, when full p-state changes are not supported, DLG parameters are calculated for no p-state support at all. However, we are required to always support dummy p-state changes, so we should instead calculate DLG based on dummy p-state latency when full p-state is unsupported. This behaviour already exists for DCN2. [How] - move DLG calculation inside WM calculation - if p-state unsupported, do not recalculate for set A, instead copy from set C, and perform DLG calculation with dummy p-state latency Signed-off-by: Joshua Aberback <joshua.aberback@amd.com> Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-09-29drm/amd/display: disable stream if pixel clock changed with link activeChiawen Huang2-4/+60
[Why] Vbios uses preferred timing to turn on edp but OS could use other timing. If change pixel clock when link active, there is unexpected garbage on monitor. [How] Once pixel clock changed, the driver needs to disable stream.

2020-09-29drm/i915: Avoid mixing integer types during batch copiesChris Wilson3-9/+12
Be consistent and use unsigned long throughout the chunk copies to avoid the inherent clumsiness of mixing integer types of different widths and signs. Failing to take acount of a wider unsigned type when using min_t can lead to treating it as a negative, only for it flip back to a large unsigned value after passing a boundary check.

2020-09-29dma-buf: Use struct dma_buf_map in dma_buf_vunmap() interfacesThomas Zimmermann8-19/+21
This patch updates dma_buf_vunmap() and dma-buf's vunmap callback to use struct dma_buf_map. The interfaces used to receive a buffer address. This address is now given in an instance of the structure. Users of the functions are updated accordingly. This is only an interface change. It is currently expected that dma-buf memory can be accessed with system memory load/store operations. v2: * include dma-buf-heaps and i915 selftests (kernel test robot) * initialize cma_obj before using it in drm_gem_cma_free_object() (kernel test robot) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Sumit Semwal <sumit.semwal@linaro.org> Acked-by: Christian König <christian.koenig@amd.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Tomasz Figa <tfiga@chromium.org> Acked-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200925115601.23955-4-tzimmermann@suse.de
