Generic fbdev emulation needs this. Also: We must keep track of the number of mappings now, so we don't unmap early in case two users want a kmap of the same bo. Add a sanity check to destroy callback to make sure kmap/kunmap is balanced. Signed-off-by:

qdev->monitors_config->max_allowed is effectively set by the qxl.num_heads module parameter, stored in the qxl_num_crtc variable. Lets get rid of the indirection and use the variable qxl_num_crtc directly. The kernel doesn't need to dereference pointers each time it needs the value, and when reading the code you don't have to trace where and why qdev->monitors_config->max_allowed is set. Signed-off-by:

The qxl device supports only a single active framebuffer ("primary surface" in spice terminology). In multihead configurations are handled by defining rectangles within the primary surface for each head/crtc. Userspace which uses the qxl ioctl interface (xorg qxl driver) is aware of this limitation and will setup framebuffers and crtcs accordingly. Userspace which uses dumb framebuffers (xorg modesetting driver, wayland) is not aware of this limitation and tries to use two framebuffers (one for each crtc) instead. The qxl kms driver already has the dumb bo separated from the primary surface, by using a (shared) shadow bo as primary surface. This is needed to support pageflips without having to re-create the primary surface. The qxl driver will blit from the dumb bo to the shadow bo instead. So we can extend the shadow logic: Maintain a global shadow bo (aka primary surface), make it big enough that dumb bo's for all crtcs fit in side-by-side. Adjust the pageflip blits to place the heads next to each other in the shadow. With this patch in place multihead qxl works with wayland. Signed-off-by: -

Pass the shadow bo to qxl_io_create_primary() instead of expecting qxl_io_create_primary to check bo->shadow. Set is_primary flag on the shadow bo. Move the is_primary tracking into qxl_io_create_primary() and qxl_io_destroy_primary() functions. That simplifies primary surface tracking and the workflow in qxl_primary_atomic_update().

Track which bo is used as primary surface. With that in place we don't need the primary_created flag any more, we can just check the primary bo pointer instead. Also verify we don't already have a primary surface in qxl_io_create_primary(). Signed-off-by:

The qxl device ties the cursor to the primary surface. Therefore calling qxl_io_destroy_primary() and qxl_io_create_primary() to switch the framebuffer causes the cursor information being lost and the driver must re-apply it. The correct call order to do that is qxl_io_destroy_primary() + qxl_io_create_primary() + qxl_primary_apply_cursor(). The old code did qxl_io_destroy_primary() + qxl_primary_apply_cursor() + qxl_io_create_primary(). Due to qxl_primary_apply_cursor request being queued in a ringbuffer and qxl_io_create_primary() trapping to the hypervisor instantly there is a high chance that qxl_io_create_primary() is processed first even with the wrong call order. But it's racy and thus not reliable. Signed-off-by:

dumb buffers are used as qxl surfaces, so allocate them as QXL_GEM_DOMAIN_SURFACE. Should usually be allocated in PRIV ttm domain then, so this reduces VRAM memory pressure. Signed-off-by:

qxl surfaces (used for framebuffers and gem objects) can live in both VRAM and PRIV ttm domains. Update placement setup to include both. Put PRIV first in the list so it is preferred, so VRAM will have more room for objects which must be allocated there. Signed-off-by:
-
Gerd Hoffmann authored
Without that ttm offsets are not unique, they can refer to objects in both VRAM and PRIV memory (aka main and surfaces slot). One of those "why things didn't blow up without this" moments. Probably offset conflicts are rare enough by pure luck. Signed-off-by:

Before assigning window data, we should check if the yuv2yuv vop-data is set at all, because it looks like it can otherwise reference something wrong, as I saw on my rk3188 today which ended up in a null pointer dereference in vop_plane_atomic_update when accessing the yuv2yuv data.

In some cases, such as running a new kernel with an old device tree that has the frontend disabled, the backend's matching frontend might be unavailable. When this happens, the layers should only declare support for formats that the backend support. This partially reverts commit 1c29d263 ("drm/sun4i: Rename sun4i_backend_layer_formats to sun4i_layer_formats") by bringing back sun4i_backend_layer_formats, and passing it to drm_universal_plane_init, while also dropping the modifiers list, in the event no frontend is available. Fixes: b636d3f9 ("drm/sun4i: frontend: Add support for the BGRX8888 input format") Fixes: 9afe52d5 ("drm/sun4i: frontend: Add support for semi-planar YUV input formats") Fixes: 8c8152bf ("drm/sun4i: frontend: Add support for planar YUV input formats") Fixes: b2ddf277 ("drm/sun4i: layer: Add tiled modifier support and helper") Signed-off-by:

The display backend does not support BGRX8888. There is also no trace of this in the original list of supported formats before the commit b636d3f9 ("drm/sun4i: frontend: Add support for the BGRX8888 input format"). Nor do the backend configuration helpers handle this format. Remove BGRX8888 from list of supported formats by the backend.

Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

syzbot is hitting a lockdep warning [1] because flush_work() is called without INIT_WORK() after kzalloc() at vkms_atomic_crtc_reset(). Commit 6c234fe3 ("drm/vkms: Implement CRC debugfs API") added INIT_WORK() to only vkms_atomic_crtc_duplicate_state() side. Assuming that lifecycle of crc_work is appropriately managed, fix this problem by adding INIT_WORK() to vkms_atomic_crtc_reset() side.

Move mipi_dsi_dcs_set_display_off() from innolux_panel_disable() to innolux_panel_unprepare(), so they are consistent with innolux_panel_enable() and innolux_panel_prepare(). This also fixes some mode check and irq timeout issue in MTK dsi code. Since some dsi code (e.g. mtk_dsi) have following call trace: 1. drm_panel_disable(), which calls innolux_panel_disable() 2. switch to cmd mode 3. drm_panel_unprepare(), which calls innolux_panel_unprepare() However, mtk_dsi needs to be in cmd mode to be able to send commands (e.g. mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode()), so we need these functions to be called after the switch to cmd mode happens, i.e. in innolux_panel_unprepare.

Consult the I2C_M_STOP flag to determine whether to set the MOT bit or not. Makes it possible to send multiple messages in one go with stop+start generated between the messages (as opposed nothing or repstart depending on whether thr address/rw changed). Not sure anyone has actual use for this but figured I'd handle it since I started to look at that flag for MST remote i2c xfers. Signed-off-by:
