* drm/vc4: Disable V3D interactions if the v3d component didn't probe.Eric Anholt2019-04-037-1/+50
| | | | | | | | | | | | | | | One might want to use the VC4 display stack without using Mesa. Similar to the debugfs fixes for not having all of the possible display bits enabled, make sure you can't oops in vc4 if v3d isn't enabled. v2: Fix matching against other v3d variants (review by Paul), don't forget to set irq_enabled so that the vblank uapi works v3: Use -ENODEV instead of -EINVAL on Paul's suggestion.

* drm/vc4: Use common helpers for debugfs setup by the driver components.Eric Anholt2019-04-0312-165/+125
| | | | | | | | | | | | | | | | | | | | | | | | The global list of all debugfs entries for the driver was painful: the list couldn't see into the components' structs, so each component had its own debugs show function to find the component, then find the regset and dump it. The components also had to be careful to check that they were actually registered in vc4 before dereferencing themselves, in case they weren't probed on a particular platform. They routinely failed at that. Instead, we can have the components add their debugfs callbacks to a little list in vc4 to be registered at drm_dev_register() time, which gets vc4_debugfs.c out of the business of knowing the whole list of components. Thanks to this change, dsi0 (if it existed) would register its node. v2: Rebase on hvs_underrun addition. v3: whitespace fixup Signed-off-by: Eric Anholt <eric@anholt.net> Link: https://patchwork.freedesktop.org/patch/msgid/20190401183559.3823-1-eric@anholt.net Reviewed-by: Paul Kocialkowski <paul.kocialkowski@bootlin.com>

* drm/lima: driver for ARM Mali4xx GPUsQiang Yu2019-04-0135-0/+4079

GP is for OpenGL vertex shader processing and PP is for fragment shader processing. Each processor has its own MMU so prcessors work in virtual address space. - There's only one GP but multiple PP (max 4 for mali 400 and 8 for mali 450) in the same mali 4xx GPU. All PPs are grouped togather to handle a single fragment shader task divided by FB output tiled pixels. Mali 400 user space driver is responsible for assign target tiled pixels to each PP, but mali 450 has a HW module called DLBU to dynamically balance each PP's load. - User space driver allocate buffer object and map into GPU virtual address space, upload command stream and draw data with CPU mmap of the buffer object, then submit task to GP/PP with a register frame indicating where is the command stream and misc settings. - There's no command stream validation/relocation due to each user process has its own GPU virtual address space. GP/PP's MMU switch virtual address space before running two tasks from different user process. Error or evil user space code just get MMU fault or GP/PP error IRQ, then the HW/SW will be recovered. - Use GEM+shmem for MM. Currently just alloc and pin memory when gem object creation. GPU vm map of the buffer is also done in the alloc stage in kernel space. We may delay the memory allocation and real GPU vm map to command submission stage in the furture as improvement. - Use drm_sched for GPU task schedule. Each OpenGL context should have a lima context object in the kernel to distinguish tasks from different user. drm_sched gets task from each lima context in a fair way. mesa driver can be found here before upstreamed: https://gitlab.freedesktop.org/lima/mesa v8: - add comments for in_sync - fix ctx free miss mutex unlock v7: - remove lima_fence_ops with default value - move fence slab create to device probe - check pad ioctl args to be zero - add comments for user/kernel interface v6: - fix comments by checkpatch.pl v5: - export gp/pp version to userspace - rebase on drm-misc-next v4: - use get param interface to get info - separate context create/free ioctl - remove unused max sched task param - update copyright time - use xarray instead of idr - stop using drmP.h v3: - fix comments from kbuild robot - restrict supported arch to tested ones v2: - fix syscall argument check - fix job finish fence leak since kernel 5.0 - use drm syncobj to replace native fence - move buffer object GPU va map into kernel - reserve syscall argument space for future info - remove kernel gem modifier - switch TTM back to GEM+shmem MM - use time based io poll - use whole register name - adopt gem reservation obj integration - use drm_timeout_abs_to_jiffies Cc: Eric Anholt <eric@anholt.net> Cc: Rob Herring <robh@kernel.org> Cc: Christian König <ckoenig.leichtzumerken@gmail.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Alex Deucher <alexdeucher@gmail.com> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Rob Clark <robdclark@gmail.com> Cc: Dave Airlie <airlied@gmail.com> Signed-off-by: Andreas Baierl <ichgeh@imkreisrum.de> Signed-off-by: Erico Nunes <nunes.erico@gmail.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Simon Shields <simon@lineageos.org> Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> Signed-off-by: Qiang Yu <yuq825@gmail.com> Reviewed-by: Eric Anholt <eric@anholt.net> Reviewed-by: Rob Herring <robh@kerrnel.org> Signed-off-by: Eric Anholt <eric@anholt.net> Link: https://patchwork.freedesktop.org/patch/291200/

* drm: rockchip: introduce rk3066 hdmiZheng Yang2019-03-316-0/+1117
| | | | | | | | | | | | | | | | | | | | | | The RK3066 HDMI TX serves as interface between a LCD Controller and a HDMI bus. A HDMI TX consists of one HDMI transmitter controller and one HDMI transmitter PHY. The interface has three (3) 8-bit data channels which can be configured for a number of bus widths (8/10/12/16/20/24-bit) and different video formats (RGB, YCbCr). Features: HDMI version 1.4a, HDCP revision 1.4 and DVI version 1.0 compliant transmitter. Supports DTV resolutions from 480i to 1080i/p HD. Master I2C interface for a DDC connection. HDMI TX supports multiple power save modes. The HDMI TX input can switch between LCDC0 and LCDC1.

* drm/virtio: rework resource creation workflow.Gerd Hoffmann2019-03-286-91/+83
| | | | | | | | | | | | | | | | | | | | | | | | This patch moves the virtio_gpu_cmd_create_resource() call (which notifies the host about the new resource created) into the virtio_gpu_object_create() function. That way we can call virtio_gpu_cmd_create_resource() before ttm_bo_init(), so the host already knows about the object when ttm initializes the object and calls our driver callbacks. Specifically the object is already created when the virtio_gpu_ttm_tt_bind() callback invokes virtio_gpu_object_attach(), so the extra virtio_gpu_object_attach() calls done after virtio_gpu_object_create() are not needed any more. The fence support for the create ioctl becomes a bit more tricky though. The code moved into virtio_gpu_object_create() too. We first submit the (fenced) virtio_gpu_cmd_create_resource() command, then initialize the ttm object, and finally attach just created object to the fence for the command in case it didn't finish yet.

* drm/virtio: use struct to pass params to virtio_gpu_object_create()Gerd Hoffmann2019-03-284-34/+35
| | | | | | | | | | | | | | | | | | | | Create virtio_gpu_object_params, use that to pass object parameters to virtio_gpu_object_create. This is just the first step, followup patches will add more parameters to the struct. The plan is to use the struct for all object parameters. Drop unused "kernel" parameter for virtio_gpu_alloc_object(), it is unused and always false. Also drop "pinned" parameter. virtio-gpu doesn't shuffle around objects, so effecively they all are pinned anyway. Hardcode TTM_PL_FLAG_NO_EVICT so ttm knows. Doesn't change much for the moment as virtio-gpu supports TTM_PL_FLAG_TT only so there is no opportunity to move around objects. That'll probably change in the future though.

| | | | | | | | | | | | | | | Drop the dummy ttm backend implementation, add a real one for TTM_PL_FLAG_TT objects. The bin/unbind callbacks will call virtio_gpu_object_{attach,detach}, to update the object state on the host side, instead of invoking those calls from the move_notify() callback. With that in place the move and move_notify callbacks are not needed any more, so drop them.
