Early versions of the legacy kernel driver included comprehensive feature lists for every GPU, even though most of the enumerated features only matter to userspace. For example, HW_FEATURE_INTERPIPE_REG_ALIASING was a feature bit indicating that a GPU had "interpipe register aliasing": arithmetic, load/store, and texture instruction all use common general-purpose registers. GPUs without this feature bit have dedicated load/store and texture "registers". Whether a GPU has this feature or not is irrelevant to the kernel; it only matters in the userspace compiler's register allocator. It's silly to enumerate it in kernel space, and the information is understandably unused. To underscore the point, this feature only makes sense in the context of the Midgard instruction set. Bifrost never had dedicated load/store or texture registers, so the feature bit was vacuously set for all Bifrost hardware, even though this conveys no useful information. To clean up the feature list, delete feature bits which could not possibly matter to the kernel, leaving only those which do affect the register-level operation of the chip. Signed-off-by:

The vga16fb framebuffer driver supports both Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But the logic to check whether the EGA or VGA standard are used is not correct. It just checks if screen_info.orig_video_isVGA is set, but it should check if is set to VIDEO_TYPE_VGAC instead. This means that it assumes to be VGA even if is set to VIDEO_TYPE_EGAC. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the change for x86 and keep the old logic for the other arches. 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:

Also introduce a *_get_drvdata() so that it can retrieved back when needed.

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.
