Because of the possible failure of the dma_supported(), the dma_set_mask_and_coherent() may return error num. Therefore, it should be better to check it and return the error if fails. Also, we can create a variable for the mask to solve the alignment issue. Fixes: 334dd38a ("drm/v3d: Set dma_mask as well as coherent_dma_mask") Signed-off-by:

Add a static entry in the x86 table, to detect and wait for privacy-screen on some ChromeOS platforms. Please note that this means that if CONFIG_CHROMEOS_PRIVACY_SCREEN is enabled, and if "GOOG0010" device is found in ACPI, then the i915 probe shall return EPROBE_DEFER until a platform driver actually registers the privacy-screen: https://hansdegoede.livejournal.com/25948.htmlSigned-off-by:

This adds the ACPI driver for the ChromeOS privacy screen that is present on some chromeos devices. Note that ideally, we'd want this privacy screen driver to be probed BEFORE the drm probe in order to avoid a drm probe deferral: https://hansdegoede.livejournal.com/25948.html In practise, I found that ACPI drivers are bound to their devices AFTER the drm probe on chromebooks. So on chromebooks with privacy-screen, this patch along with the other one in this series results in a probe deferral of about 250ms for i915 driver. However, it did not result in any user noticeable delay of splash screen in my personal experience. In future if this probe deferral turns out to be an issue, we can consider turning this ACPI driver into something that is probed earlier than the drm drivers. Signed-off-by:

Allow a privacy screen provider to stash its private data pointer in the drm_privacy_screen, and update the drm_privacy_screen_register() call to accept that. Also introduce a *_get_drvdata() so that it can retrieved back when needed. This also touches the IBM Thinkpad platform driver, the only user of privacy screen today, to pass NULL for now to the updated API. Signed-off-by:

Existing HPD enablement logic is not compatible with ADV7535 bridge, thus any runtime plug-in of HDMI cable is not working on these bridge designs.

Currently omapdrm driver does not initialize dma_buf_export_info resv member, which leads to a new dma_resv being allocated and attached to the exported dma_buf. This leads to the issue that fences created on dma_buf objects imported by other drivers are ignored by omapdrm, as only fences in gem object resv are waited on. This leads to various issues like displaying incomplete frames. Fix that by initializing dma_buf resv to the resv of the gem object being exported. Signed-off-by:

José Expósito authored
The documentation for "drm_plane_funcs.format_mod_supported" reads: This *optional* hook is used for the DRM to determine if the given format/modifier combination is valid for the plane. This allows the DRM to generate the correct format bitmask (which formats apply to which modifier), and to validate modifiers at atomic_check time. *If not present*, then any modifier in the plane's modifier list is allowed with any of the plane's formats. However, where the function is not present, an invalid IN_FORMATS blob property with modifiers but no formats is exposed to user-space. This breaks the latest Weston [1]. For testing purposes, I extracted the affected code to a standalone program [2]. Make "create_in_format_blob" behave as documented.

Entering suspend while the display attached to this bridge is still on makes the resume sequence to resume the bridge first, display last: when this happens, we get a timeout while resuming the bridge, as its MCU will get stuck due to the display being unpowered. On the other hand, on mt8173-elm, closing the lid makes the display to get powered off first, bridge last, so at resume time the sequence is swapped (compared to the first example) and everything just works as expected. Add a stateless device link to the DRM device that this bridge belongs to, ensuring a correct resume sequence and solving the unability to correctly resume bridge operation in the first mentioned example.

Some display panels would come up with a non-DSI output, those can have an option to connect the DSI host by means of interface bridge converter. This DSI to non-DSI interface bridge converter would requires DSI Host to handle drm bridge functionalities in order to DSI Host to Interface bridge.
