drm/virtio: fix resource id creation race

2020-03-12T12:00:24Z

commit fbb30168c7395b9cfeb9e6f7b0c0bca854a6552d upstream. The previous code was not thread safe and caused undefined behavior from spurious duplicate resource IDs. In this patch, an atomic_t is used instead. We no longer see any duplicate IDs in tests with this change.

Revert "drm/virtio: switch virtio_gpu_wait_ioctl() to gem helper."

2020-01-17T18:48:51Z

This reverts commit e6733ec8948475c4b62574e452135dc629294d75 which is commit 29cf12394c0565d7eb1685bf0c1b4749aa6a8b66 upstream. Alistair writes: After updating to 5.4.7 we noticed that virtio_gpu's wait ioctl stopped working correctly. It looks like 29cf12394c05 ("drm/virtio: switch virtio_gpu_wait_ioctl() to gem helper.") was picked up automatically, but it depends on 889165ad6190 ("drm/virtio: pass gem reservation object to ttm init") from earlier in Gerd's series in Linus's tree, which was not picked up.

drm/virtio: switch virtio_gpu_wait_ioctl() to gem helper.

2019-12-31T15:42:16Z

[ Upstream commit 29cf12394c0565d7eb1685bf0c1b4749aa6a8b66 ] Use drm_gem_reservation_object_wait() in virtio_gpu_wait_ioctl(). This also makes the ioctl run lockless. v9: fix return value. v5: handle lookup failure. v2: use reservation_object_test_signaled_rcu for VIRTGPU_WAIT_NOWAIT.

Pull drm updates from Dave Airlie: "This is the main pull request for 5.4-rc1 merge window. I don't think there is anything outstanding so next week should just be fixes, but we'll see if I missed anything. I landed some fixes earlier in the week but got delayed writing summary and sending it out, due to a mix of sick kid and jetlag! There are some fixes pending, but I'd rather get the main merge out of the way instead of delaying it longer. It's also pretty large in commit count and new amd header file size. The largest thing is four new amdgpu products (navi12/14, arcturus and renoir APU support). Otherwise it's pretty much lots of work across the board, i915 has started landing tigerlake support, lots of icelake fixes and lots of locking reworking for future gpu support, lots of header file rework (drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been put into the places they are needed. uapi: - content protection type property for HDCP core: - rework include dependencies - lots of drmP.h removals - link rate calculation robustness fix - make fb helper map only when required - add connector->DDC adapter link - DRM_WAIT_ON removed - drop DRM_AUTH usage from drivers dma-buf: - reservation object fence helper dma-fence: - shrink dma_fence struct - merge signal functions - store timestamps in dma_fence - selftests ttm: - embed drm_get_object struct into ttm_buffer_object - release_notify callback bridges: - sii902x - audio graph card support - tc358767 - aux data handling rework - ti-snd64dsi86 - debugfs support, DSI mode flags support panels: - Support for GiantPlus GPM940B0, Sharp LQ070Y3DG3B, Ortustech COM37H3M, Novatek NT39016, Sharp LS020B1DD01D, Raydium RM67191, Boe Himax8279d, Sharp LD-D5116Z01B - TI nspire, NEC NL8048HL11, LG Philips LB035Q02, Sharp LS037V7DW01, Sony ACX565AKM, Toppoly TD028TTEC1 Toppoly TD043MTEA1 i915: - Initial tigerlake platform support - Locking simplification work, general all over refactoring. - Selftests - HDCP debug info improvements - DSI properties - Icelake display PLL fixes, colorspace fixes, bandwidth fixes, DSI suspend/resume - GuC fixes - Perf fixes - ElkhartLake enablement - DP MST fixes - GVT - command parser enhancements amdgpu: - add wipe memory on release flag for buffer creation - Navi12/14 support (may be marked experimental) - Arcturus support - Renoir APU support - mclk DPM for Navi - DC display fixes - Raven scatter/gather support - RAS support for GFX - Navi12 + Arcturus power features - GPU reset for Picasso - smu11 i2c controller support amdkfd: - navi12/14 support - Arcturus support radeon: - kexec fix nouveau: - improved display color management - detect lack of GPU power cables vmwgfx: - evicition priority support - remove unused security feature msm: - msm8998 display support - better async commit support for cursor updates etnaviv: - per-process address space support - performance counter fixes - softpin support mcde: - DCS transfers fix exynos: - drmP.h cleanup lima: - reduce logging kirin: - misc clenaups komeda: - dual-link support - DT memory regions hisilicon: - misc fixes imx: - IPUv3 image converter fixes - 32-bit RGB V4L2 pixel format support ingenic: - more support for panel related cases mgag200: - cursor support fix panfrost: - export GPU features register to userspace - gpu heap allocations - per-fd address space support pl111: - CLD pads wiring support removed from DT rockchip: - rework to use DRM PSR helpers - fix bug in VOP_WIN_GET macro - DSI DT binding rework sun4i: - improve support for color encoding and range - DDC enabled GPIO tinydrm: - rework SPI support - improve MIPI-DBI support - moved to drm/tiny vkms: - rework CRC tracking dw-hdmi: - get_eld and i2s improvements gm12u320: - misc fixes meson: - global code cleanup - vpu feature detect omap: - alpha/pixel blend mode properties rcar-du: - misc fixes" * tag 'drm-next-2019-09-18' of git://anongit.freedesktop.org/drm/drm: (2112 commits) drm/nouveau/bar/gm20b: Avoid BAR1 teardown during init drm/nouveau: Fix ordering between TTM and GEM release drm/nouveau/prime: Extend DMA reservation object lock drm/nouveau: Fix fallout from reservation object rework drm/nouveau/kms/nv50-: Don't create MSTMs for eDP connectors drm/i915: Use NOEVICT for first pass on attemping to pin a GGTT mmap drm/i915: to make vgpu ppgtt notificaiton as atomic operation drm/i915: Flush the existing fence before GGTT read/write drm/i915: Hold irq-off for the entire fake lock period drm/i915/gvt: update RING_START reg of vGPU when the context is submitted to i915 drm/i915/gvt: update vgpu workload head pointer correctly drm/mcde: Fix DSI transfers drm/msm: Use the correct dma_sync calls harder drm/msm: remove unlikely() from WARN_ON() conditions drm/msm/dsi: Fix return value check for clk_get_parent drm/msm: add atomic traces drm/msm/dpu: async commit support drm/msm: async commit support drm/msm: split power control from prepare/complete_commit drm/msm: add kms->flush_commit() ...

drm/virtio: use virtio_max_dma_size

We must make sure our scatterlist segments are not too big, otherwise we might see swiotlb failures (happens with sev, also reproducable with swiotlb=force).
