2023-11-24drm/vboxvideo: Use the hotspot properties from cursor planesZack Rusin1-2/+2
Atomic modesetting got support for mouse hotspots via the hotspot properties. Port the legacy kms hotspot handling to the new properties on cursor planes.

2023-11-24drm: Disable the cursor plane on atomic contexts with virtualized driversZack Rusin1-1/+1
Cursor planes on virtualized drivers have special meaning and require that the clients handle them in specific ways, e.g. the cursor plane should react to the mouse movement the way a mouse cursor would be expected to and the client is required to set hotspot properties on it in order for the mouse events to be routed correctly. This breaks the contract as specified by the "universal planes". Fix it by disabling the cursor planes on virtualized drivers while adding a foundation on top of which it's possible to special case mouse cursor planes for clients that want it. Disabling the cursor planes makes some kms compositors which were broken, e.g. Weston, fallback to software cursor which works fine or at least better than currently while having no effect on others, e.g. gnome-shell or kwin, which put virtualized drivers on a deny-list when running in atomic context to make them fallback to legacy kms and avoid this issue.

2023-09-21drm: Call drm_atomic_helper_shutdown() at shutdown/remove time for misc driversDouglas Anderson1-0/+10
Based on grepping through the source code these drivers appear to be missing a call to drm_atomic_helper_shutdown() at system shutdown time and at driver remove (or unbind) time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart and at driver remove (or unbind) time comes straight out of the kernel doc "driver instance overview" in drm_drv.c. A few notes about these fixes: - I confirmed that these drivers were all DRIVER_MODESET type drivers, which I believe makes this relevant. - I confirmed that these drivers were all DRIVER_ATOMIC. - When adding drm_atomic_helper_shutdown() to the remove/unbind path, I added it after drm_kms_helper_poll_fini() when the driver had it. This seemed to be what other drivers did. If drm_kms_helper_poll_fini() wasn't there I added it straight after drm_dev_unregister(). - This patch deals with drivers using the component model in similar ways as the patch ("drm: Call drm_atomic_helper_shutdown() at shutdown time for misc drivers") - These fixes rely on the patch ("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop") to simplify shutdown.

2022-12-12drm: vboxvideo: Remove #ifdef guards for PM related functionsPaul Cercueil1-5/+1
Use the pm_sleep_ptr() macro to handle the .suspend / .resume callbacks. This macro allows the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

2022-02-08dma-buf-map: Rename to iosys-mapLucas De Marchi1-2/+2
Rename struct dma_buf_map to struct iosys_map and corresponding APIs. Over time dma-buf-map grew up to more functionality than the one used by dma-buf: in fact it's just a shim layer to abstract system memory, that can be accessed via regular load and store, from IO memory that needs to be acessed via arch helpers. The idea is to extend this API so it can fulfill other needs, internal to a single driver. Example: in the i915 driver it's desired to share the implementation for integrated graphics, which uses mostly system memory, with discrete graphics, which may need to access IO memory. The conversion was mostly done with the following semantic patch: @r1@ @@ - struct dma_buf_map + struct iosys_map @r2@ @@ ( - DMA_BUF_MAP_INIT_VADDR + IOSYS_MAP_INIT_VADDR | - dma_buf_map_set_vaddr + iosys_map_set_vaddr | - dma_buf_map_set_vaddr_iomem + iosys_map_set_vaddr_iomem | - dma_buf_map_is_equal + iosys_map_is_equal | - dma_buf_map_is_null + iosys_map_is_null | - dma_buf_map_is_set + iosys_map_is_set | - dma_buf_map_clear + iosys_map_clear | - dma_buf_map_memcpy_to + iosys_map_memcpy_to | - dma_buf_map_incr + iosys_map_incr ) @@ @@ - #include <linux/dma-buf-map.h> + #include <linux/iosys-map.h> Then some files had their includes adjusted and some comments were update to remove mentions to dma-buf-map.

The "nomodeset" kernel cmdline parameter is handled by the vgacon driver but the exported vgacon_text_force() symbol is only used by DRM drivers. It makes much more sense for the parameter logic to be in the subsystem of the drivers that are making use of it. Let's move the vgacon_text_force() function and related logic to the DRM subsystem. While doing that, rename it to drm_firmware_drivers_only() and make it return true if "nomodeset" was used and false otherwise.

2021-02-09drm/vboxvideo: Implement cursor plane with struct drm_shadow_plane_stateThomas Zimmermann1-21/+7
Functions in the atomic commit tail are not allowed to acquire the dmabuf's reservation lock. So we cannot legally call the GEM object's vmap functionality in atomic_update. Instead use struct drm_shadow_plane_state and friends. It vmaps the framebuffer BOs in prepare_fb and vunmaps them in cleanup_fb. The cursor plane state stores the mapping's address. The pinning of the BO is implicitly done by vmap. As an extra benefit, there's no source of runtime errors left in atomic_update. v2: * rebase patch onto struct drm_shadow_plane_state Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Tested-by: Hans de Goede <hdegoede@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210209121042.24098-3-tzimmermann@suse.de

2020-04-08drm/vboxvideo: Set up fbdev after registering device; remove error checksThomas Zimmermann1-4/+2
Generic fbdev support is a DRM client. Set it up after registering the new DRM device. Remove the error checks as the driver's probe function should not depend on a DRM client's state.

2020-03-26drm/vboxvideo: Add missing remove_conflicting_pci_framebuffers call, v2Hans de Goede1-0/+4
The vboxvideo driver is missing a call to remove conflicting framebuffers. Surprisingly, when using legacy BIOS booting this does not really cause any issues. But when using UEFI to boot the VM then plymouth will draw on both the efifb /dev/fb0 and /dev/drm/card0 (which has registered /dev/fb1 as fbdev emulation). VirtualBox will actual display the output of both devices (I guess it is showing whatever was drawn last), this causes weird artifacts because of pitch issues in the efifb when the VM window is not sized at 1024x768 (the window will resize to its last size once the vboxvideo driver loads, changing the pitch). Adding the missing drm_fb_helper_remove_conflicting_pci_framebuffers() call fixes this. Changes in v2: -Make the drm_fb_helper_remove_conflicting_pci_framebuffers() call one of the first things we do in our probe() method Cc: stable@vger.kernel.org Fixes: 2695eae1f6d3 ("drm/vboxvideo: Switch to generic fbdev emulation") Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20200325144310.36779-1-hdegoede@redhat.com
