2021-07-15drm/vc4: hdmi: Only call into DRM framework if registeredMaxime Ripard1-1/+1
Our hotplug handler will currently call the drm_kms_helper_hotplug_event every time a hotplug interrupt is called. However, since the device is registered after all the drivers have finished their bind callback, we have a window between when we install our interrupt handler and when drm_dev_register() is eventually called where our handler can run and call drm_kms_helper_hotplug_event but the device hasn't been registered yet, causing a null pointer dereference. Fix this by making sure we only call drm_kms_helper_hotplug_event if our device has been properly registered.

2021-07-15drm/vc4: hdmi: Drop devm interrupt handler for hotplug interruptsMaxime Ripard1-13/+28
The hotplugs interrupt handlers are registered through the devm_request_threaded_irq function. However, while free_irq is indeed called properly when the device is unbound or bind fails, it's called after unbind or bind is done. In our particular case, it means that on failure it creates a window where our interrupt handler can be called, but we're freeing every resource (CEC adapter, DRM objects, etc.) it might need. In order to address this, let's switch to the non-devm variant to control better when the handler will be unregistered and allow us to make it safe.

We were getting a depmod error: depmod: ERROR: Cycle detected: drm_kms_helper -> drm -> drm_kms_helper It looks like the rule is that drm_kms_helper can call into drm, but drm can't call into drm_kms_helper. That means we've got to move the DP AUX backlight support into drm_dp_helper. NOTE: as part of this, I didn't try to do any renames of the main registration function. Even though it's in the drm_dp_helper, it still feels very parallel to drm_panel_of_backlight().

2021-07-13drm/vkms: Use dma-buf mapping from shadow-plane state for composingThomas Zimmermann3-13/+15
Store the shadow-buffer mapping's address in struct vkms_composer and use the value when composing the output. It's the same value as stored in the GEM SHMEM BO, but frees the composer code from its dependency on GEM SHMEM. Using struct dma_buf_map is how framebuffer access is supposed to be. The long-term plan is to perform all framebuffer access via struct dma_buf_map and avoid the details of accessing I/O and system memory.

This change also fixes a problem where IGT kms_flip tests would create a segmentation fault within vkms. The driver's prepare_fb function did not report an error if a BO's vmap operation failed.

2021-07-09drm/panel: add basic DP AUX backlight supportRajeev Nandan1-0/+108
Some panels support backlight control over DP AUX channel using VESA's standard backlight control interface. Using new DRM eDP backlight helpers, add support to create and register a backlight for those panels in drm_panel to simplify the panel drivers. The panel driver with access to "struct drm_dp_aux" can create and register a backlight device using following code snippet in its probe() function: err = drm_panel_dp_aux_backlight(panel, aux); if (err) return err; Then drm_panel will handle backlight_(enable|disable) calls similar to the case when drm_panel_of_backlight() is used. Currently, we are not supporting one feature where the source device can combine the backlight brightness levels set through DP AUX and the BL_PWM_DIM eDP connector pin. Since it's not required for the basic backlight controls, it can be added later.

2021-07-08drm/gud: Use scatter-gather USB bulk transferNoralf Trønnes3-21/+78
There'a limit to how big a kmalloc buffer can be, and as memory gets fragmented it becomes more difficult to get big buffers. The downside of smaller buffers is that the driver has to split the transfer up which hampers performance. Compression might also take a hit because of the splitting. Solve this by allocating the transfer buffer using vmalloc and create a SG table to be passed on to the USB subsystem. vmalloc_32() is used to avoid DMA bounce buffers on USB controllers that can only access 32-bit addresses. This also solves the problem that split transfers can give host side tearing since flushing is decoupled from rendering. usb_sg_wait() doesn't have timeout handling builtin, so it is wrapped in a timer like 4 out of 6 users in the kernel have done. v2: - Use DIV_ROUND_UP (Linus) - Add timeout note to the commit log (Linus) - Expand note about upper buffer limit (Linus) - Change var name s/timer/ctx/ in gud_usb_bulk_timeout() Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210701170748.58009-2-noralf@tronnes.org

The function qxl_gem_prime_mmap() returns an error. The two callers of gem_prime_mmap are drm_fbdev_fb_mmap() and drm_gem_dmabuf_mmap(), which both already handle NULL-callbacks with an error code. So clear gem_prime_mmap in qxl and remove qxl_gem_prime_mmap().

2021-07-06drm: vc4: Fix pixel-wrap issue with DVP teardownTim Gover1-7/+8
Adjust the DVP enable/disable sequence to avoid a pixel getting stuck in an internal, non resettable FIFO within PixelValve when changing HDMI resolution. The blank pixels features of the DVP can prevent signals back to pixelvalve causing it to not clear the FIFO. Adjust the ordering and timing of operations to ensure the clear signal makes it through to pixelvalve.

2021-07-06drm/vc4: hdmi: Limit noise when deferring snd card registrationNicolas Saenz Julienne1-1/+1
We don't want to print an error message each time devm_snd_soc_register_card() returns -EPROBE_DEFER, the function will most likely succeed some time in the future, once the missing resources are available. So use dev_err_probe(), which will redirect the messages to the debug log level in such case.

2021-07-06drm/vgem: Implement mmap as GEM object functionThomas Zimmermann1-41/+5
Moving the driver-specific mmap code into a GEM object function allows for using DRM helpers for various mmap callbacks. The respective vgem functions are being removed. The file_operations structure vgem_driver_fops is now being created by the helper macro DEFINE_DRM_GEM_FOPS().
