It is possible to run out of memory while allocating IDs. The current code would create a context with an invalid ID; change it to return -ENOMEM to userspace. Signed-off-by:

These IDRs were only being used to allocate unique numbers, not to look up pointers, so they can use the more space-efficient IDA instead. Signed-off-by:

Move virtio_gpu_resource_id_{get,put} to virtgpu_object.c and make them static. Allocate and free the id on creation and destroy, drop all other calls. That way objects have a valid handle for the whole lifetime of the object. Also fixes ids leaking. Worst offender are dumb buffers, and I think some error paths too.

Track whenever the virtio_gpu_object is already created (i.e. host knows about it) in a new variable. Add checks to virtio_gpu_object_attach() to do nothing on objects not created yet. Make virtio_gpu_ttm_bo_destroy() use the new variable too, instead of expecting hw_res_handle indicating the object state. Signed-off-by:

The is_double flag is a boolean currently assigned to the value of the d variable, that is either 1 or 2. It means that this is_double variable is always set to true, even though the initial intent was to have it set to true when d is 2. Fix this.

The is_double variable is used to store, and possibly returning to the calling function, whether it needs to double the rate of the parent clock or not. In the case where it does, the variable is affected, but in the case where it doesn't we return some uninitialized value. Fix this. Reported-by:

Earlier commit updated the vgem driver to improve the topology, by passing a platform device as parent to drm_dev_init(). Shortly afterwords we updated the core function to BUG() in order to catch any buggy drivers passing NULL as parent. While I missed the vkms driver (as the patch predates vkms by a few months), the BUG caught the issue within couple of hours. Swap the drm_dev_init <> platform_device_register_simple order, to the driver back to life.

HDMI 2.0 monitors may not support SCDC and still be able to accept VICs above 63. Use multiple EDID capbilities to determine if the SINK is actually an HDMI 2.0 device. The QD980B HDMI 2.0 Analyzer generates unique EDIDs during CTS tests that don't contain a HDMI Forum VSDB if the block is not used during the test. The current HDMI AVI infoframe code only uses the SCDC supported information in the HDMI Forum VSDB to determine if the sink is HDMI 2.0. This patch adds a check for YCbCr420 present in the EDID supported formats as well as the existing SCDC supported check. HDMI 2.0 CTS HF1-51 test fails on the QD980B.

The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.

A while back we removed it, yet that lead to regressions. At some later point, I've attempted to remove it again without fully grasping the unique (pun intended) situation that virtio is in. Add a bulky comment to document why the call should stay as-is, for the next person who's around. As a Tl;Dr: virtio sits on top of struct virtio_device, which confuses dev_is_pci(), wrong info gets sent to userspace and X doesn't start. Driver needs to explicitly call drm_dev_set_unique() to keep it working. v2: Fix handful of typos (Laszlo) Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Hans de Goede <hdegoede@redhat.com> Cc: Laszlo Ersek <lersek@redhat.com> Signed-off-by:

There's no reason to track the atomic state three times. Unfortunately, this is currently what we're doing, and even worse is that there is only one actually correct state pointer: the one in mst_state->base.state. mgr->state never seems to be used, along with the one in mst_state->state. This confused me for over 4 hours until I realized there was no magic behind these pointers. So, let's save everyone else from the trouble. Signed-off-by: Lyude Paul <lyude@redhat.com>.

The offset adjustment depends on the framebuffer modified, so let's just move this operation in the DRM_FORMAT_MOD_LINEAR case inside vc4_plane_mode_set(). This we'll be able to fix offset calculation for DRM_FORMAT_MOD_BROADCOM_VC4_T_TILED and DRM_FORMAT_MOD_BROADCOM_SANDXXX. Signed-off-by:

The DSI devices have a maximum operating frequency specified in their data sheet per the MIPI specification, and DSI hosts that can scale their frequency need this information to set their clock dividers right.
