2024-10-30accel/ivpu: Use xa_alloc_cyclic() instead of custom functionKarol Wachowski
Remove custom ivpu_id_alloc() wrapper used for ID allocations and replace it with standard xa_alloc_cyclic() API. The idea behind ivpu_id_alloc() was to have monotonic IDs, so the driver is easier to debug because same IDs are not reused all over. The same can be achieved just by using appropriate Linux API.

2024-10-30accel/ivpu: Defer MMU root page table allocationKarol Wachowski
Defer root page table allocation and unify context init/fini functions. Move allocation of the root page table from the file_priv_open function to perform a lazy allocation approach during ivpu_bo_pin(). By doing so, we avoid the overhead of allocating page tables for simple operations like GET_PARAM that do not require them. Additionally, the MMU context descriptor table initialization has been moved to the ivpu_mmu_context_map_page function. This change streamlines the process and ensures that the descriptor table is only initialized when it is actually needed. Refactor init/fini functions to remove redundant code and make the context management more straightforward. Overall, these changes lead to a reduction in the time taken by the file descriptor open operation, as the costly root page table allocation is now avoided for operations that do not require it.

2024-10-25accel/qaic: Add crashdump to SaharaJeffrey Hugo
The Sahara protocol has a crashdump functionality. In the hello exchange, the device can advertise it has a memory dump available for the host to collect. Instead of the device making requests of the host, the host requests data from the device which can be later analyzed. Implement this functionality and utilize the devcoredump framework for handing the dump over to userspace. Similar to how firmware loading in Sahara involves multiple files, crashdump can consist of multiple files for different parts of the dump. Structure these into a single buffer that userspace can parse and extract the original files from.

2024-10-22drm/sched: memset() 'job' in drm_sched_job_init()Philipp Stanner
drm_sched_job_init() has no control over how users allocate struct drm_sched_job. Unfortunately, the function can also not set some struct members such as job->sched. This could theoretically lead to UB by users dereferencing the struct's pointer members too early. It is easier to debug such issues if these pointers are initialized to NULL, so dereferencing them causes a NULL pointer exception. Accordingly, drm_sched_entity_init() does precisely that and initializes its struct with memset(). Initialize parameter "job" to 0 in drm_sched_job_init().

2024-10-19drm/fsl-dcu: Remove redundant dev_err()Chen Ni
There is no need to call the dev_err() function directly to print a custom message when handling an error from platform_get_irq() function as it is going to display an appropriate error message in case of a failure.

2024-10-18accel/qaic: Pass string literal as format argument of alloc_workqueue()Simon Horman
Recently I noticed that both gcc-14 and clang-18 report that passing a non-string literal as the format argument of alloc_workqueue() is potentially insecure. E.g. clang-18 says: .../qaic_drv.c:61:23: warning: format string is not a string literal (potentially insecure) [-Wformat-security] 61 | wq = alloc_workqueue(fmt, WQ_UNBOUND, 0); | ^~~ .../qaic_drv.c:61:23: note: treat the string as an argument to avoid this 61 | wq = alloc_workqueue(fmt, WQ_UNBOUND, 0); | ^ | "%s", It is always the case where the contents of fmt is safe to pass as the format argument. That is, in my understanding, it never contains any format escape sequences. But, it seems better to be safe than sorry. And, as a bonus, compiler output becomes less verbose by addressing this issue as suggested by clang-18. Also, change the name of the parameter of qaicm_wq_init from fmt to name to better reflect it's purpose. Compile tested only.

2024-10-18drm/display: Drop obsolete dependency on COMPILE_TESTJean Delvare
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. To avoid reintroducing the randconfig bug originally fixed by commit 876271118aa4 ("drm/display: Fix build error without CONFIG_OF"), DRM_MSM which selects DRM_DISPLAY_DP_HELPER must explicitly depend on OF. This is consistent with what all other DRM drivers are doing.

2024-10-18drm/client: Add client-lib moduleThomas Zimmermann
Add drm_client_lib.ko to contain DRM's built-in client. Move the existing client for fbdev emulation into the new module. Protect the new module behind CONFIG_DRM_CLIENT_LIB. The Kconfig rules separate the DRM drivers from the DRM clients. A driver can opt into the default clients, but the user configures each client individually. To do so, DRM drivers still select DRM_CLIENT_SELECTION. The option is now a tristate that further selects all dependencies of the enabled DRM clients. There's a menu option for each client. Enabling at least one client also selects DRM_CLIENT_SETUP, so that drivers call drm_client_setup(). New DRM clients should depend on DRM_CLIENT_SELECTION. There are existing kernel options in drm_fb_helper.o, so leave this file in the KMS-helper module for now. v5: - leave fbdev helpers in drm_kms_helper.ko for now v3: - fix commit changelog v2: - keep client code in core - protect lib with DRM_CLIENT_LIB - remove duplicate line from Makefile (Jocelyn) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241014085740.582287-13-tzimmermann@suse.de

If client support has been disabled, the helpers for client-related events are empty and the regular client functions are not present.
