2024-11-04drm/vkms: Remove usage of legacy drm_crtc membersLouis Chauvet
Some members of the drm_crtc structure have been deprecated in favor of equivalent members in the drm_crtc_state structure. As reported by Ville Syrjala [1], the VKMS driver was still using these deprecated fields. This commit updates the VKMS driver to use the new drm_crtc_state fields instead. Additionally, this commit removes the call to `drm_calc_timestamping_constants` in `vkms_enable_vblank` as it is redundant. This calculation is already performed in `vkms_atomic_commit_tail` by calling `drm_atomic_helper_commit_modeset_disables`.

2024-11-04drm/bridge: it6505: Fix inverted reset polarityChen-Yu Tsai
The IT6505 bridge chip has a active low reset line. Since it is a "reset" and not an "enable" line, the GPIO should be asserted to put it in reset and deasserted to bring it out of reset during the power on sequence. The polarity was inverted when the driver was first introduced, likely because the device family that was targeted had an inverting level shifter on the reset line. The MT8186 Corsola devices already have the IT6505 in their device tree, but the whole display pipeline is actually disabled and won't be enabled until some remaining issues are sorted out. The other known user is the MT8183 Kukui / Jacuzzi family; their device trees currently do not have the IT6505 included. Fix the polarity in the driver while there are no actual users.

2024-11-02Input: fix regression when re-registering input handlersDmitry Torokhov
Commit d469647bafd9 ("Input: simplify event handling logic") introduced code that would set handler->events() method to either input_handler_events_filter() or input_handler_events_default() or input_handler_events_null(), depending on the kind of input handler (a filter or a regular one) we are dealing with. Unfortunately this breaks cases when we try to re-register the same filter (as is the case with sysrq handler): after initial registration the handler will have 2 event handling methods defined, and will run afoul of the check in input_handler_check_methods(): input: input_handler_check_methods: only one event processing method can be defined (sysrq) sysrq: Failed to register input handler, error -22 Fix this by adding handle_events() method to input_handle structure and setting it up when registering a new input handle according to event handling methods defined in associated input_handler structure, thus avoiding modifying the input_handler structure.

The recent attempt to make the MediaTek DRM driver build for non-ARM compile tests made the driver unbuildable for arm64 platforms. Since this is used on both ARM and arm64 platforms, just drop the dependency on ARM.

The gpiolib debugfs interface exports a list of all gpio chips in a system and the state of their pins. The gpio chip sections are supposed to be separated by a newline character, but a long-standing bug prevents the separator from being included when output is generated in multiple sessions, making the output inconsistent and hard to read.

2024-10-31drm/xe: Don't short circuit TDR on jobs not startedMatthew Brost
Short circuiting TDR on jobs not started is an optimization which is not required. On LNL we are facing an issue where jobs do not get scheduled by the GuC if it misses a GGTT page update. When this occurs let the TDR fire, toggle the scheduling which may get the job unstuck, and print a warning message. If the TDR fires twice on job that hasn't started, timeout the job. v2: - Add warning message (Paulo) - Add fixes tag (Paulo) - Timeout job which hasn't started after TDR firing twice v3: - Include local change v4: - Short circuit check_timeout on job not started - use warn level rather than notice (Paulo) Fixes: 7ddb9403dd74 ("drm/xe: Sample ctx timestamp to determine if jobs have timed out") Cc: stable@vger.kernel.org Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241025214330.2010521-2-matthew.brost@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> (cherry picked from commit 35d25a4a0012e690ef0cc4c5440231176db595cc) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
2024-10-31drm/xe: Add mmio read before GGTT invalidateMatthew Brost
On LNL without a mmio read before a GGTT invalidate the GuC can incorrectly read the GGTT scratch page upon next access leading to jobs not getting scheduled. A mmio read before a GGTT invalidate seems to fix this. Since a GGTT invalidate is not a hot code path, blindly do a mmio read before each GGTT invalidate.

Fix an issue detected by the Smatch tool: drivers/gpio/gpiolib-swnode.c:78 swnode_find_gpio() error: uninitialized symbol 'ret'. The issue occurs because the 'ret' variable may be used without initialization if the for_each_gpio_property_name loop does not run. This could lead to returning an undefined value, causing unpredictable behavior. Initialize 'ret' to 0 before the loop to ensure the function returns an error code if no properties are parsed, maintaining proper error handling.

2024-10-31net: hns3: fixed hclge_fetch_pf_reg accesses bar space out of bounds issueHao Lan
The TQP BAR space is divided into two segments. TQPs 0-1023 and TQPs 1024-1279 are in different BAR space addresses. However, hclge_fetch_pf_reg does not distinguish the tqp space information when reading the tqp space information. When the number of TQPs is greater than 1024, access bar space overwriting occurs. The problem of different segments has been considered during the initialization of tqp.io_base. Therefore, tqp.io_base is directly used when the queue is read in hclge_fetch_pf_reg.

2024-10-31net: hns3: Resolved the issue that the debugfs query result is inconsistent.Hao Lan
This patch modifies the implementation of debugfs: When the user process stops unexpectedly, not all data of the file system is read. In this case, the save_buf pointer is not released. When the user process is called next time, save_buf is used to copy the cached data to the user space. As a result, the queried data is inconsistent. To solve this problem, determine whether the function is invoked for the first time based on the value of *ppos. If *ppos is 0, obtain the actual data.

2024-10-31net: hns3: fix missing features due to dev->features configuration too earlyHao Lan
Currently, the netdev->features is configured in hns3_nic_set_features. As a result, __netdev_update_features considers that there is no feature difference, and the procedures of the real features are missing.
