| * media: qcom: camss: Restructure camss_link_entitiesVikram Sharma2024-12-041-52/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor the camss_link_entities function by breaking it down into three distinct functions. Each function will handle the linking of a specific entity separately. SC7280 and later targets mandates for 1:1 linking for csid -> vfe. i.e. csid0 can be mapped to vfe0 only.

| * media: imx-jpeg: Fix potential error pointer dereference in detach_pm()Dan Carpenter2024-12-021-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The proble is on the first line: if (jpeg->pd_dev[i] && !pm_runtime_suspended(jpeg->pd_dev[i])) If jpeg->pd_dev[i] is an error pointer, then passing it to pm_runtime_suspended() will lead to an Oops. The other conditions check for both error pointers and NULL, but it would be more clear to use the IS_ERR_OR_NULL() check for that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The platform compatibility checks for MT8183 and MT8195 in mdp_cmdq_prepare() are redundant as they are done in __get_config_offset() itself. Furthermore there are two if-else branch in __get_config_offset() which have similar conditions and are redundant. To address this, remove the check in mdp_cmdq_prepare() and combine the two if-else branch into one in __get_config_offset().

This is currently handled by smpboot code which takes care of CPU-hotplug operations. Affinity here is a correctness constraint. 2) Some kthreads _have_ to be affine to a specific set of CPUs and can't run anywhere else. The affinity is set through kthread_bind_mask() and the subsystem takes care by itself to handle CPU-hotplug operations. Affinity here is assumed to be a correctness constraint. 3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This is not a correctness constraint but merely a preference in terms of memory locality. kswapd and kcompactd both fall into this category. The affinity is set manually like for any other task and CPU-hotplug is supposed to be handled by the relevant subsystem so that the task is properly reaffined whenever a given CPU from the node comes up. Also care should be taken so that the node affinity doesn't cross isolated (nohz_full) cpumask boundaries. 4) Similar to the previous point except kthreads have a _preferred_ affinity different than a node. Both RCU boost kthreads and RCU exp kworkers fall into this category as they refer to "RCU nodes" from a distinctly distributed tree. Currently the preferred affinity patterns (3 and 4) have at least 4 identified users, with more or less success when it comes to handle CPU-hotplug operations and CPU isolation. Each of which do it in its own ad-hoc way. This is an infrastructure proposal to handle this with the following API changes: - kthread_create_on_node() automatically affines the created kthread to its target node unless it has been set as per-cpu or bound with kthread_bind[_mask]() before the first wake-up. - kthread_affine_preferred() is a new function that can be called right after kthread_create_on_node() to specify a preferred affinity different than the specified node. When the preferred affinity can't be applied because the possible targets are offline or isolated (nohz_full), the kthread is affine to the housekeeping CPUs (which means to all online CPUs most of the time or only the non-nohz_full CPUs when nohz_full= is set). kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been converted, along with a few old drivers. Summary of the changes: - Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu() - Introduce task_cpu_fallback_mask() that defines the default last resort affinity of a task to become nohz_full aware - Add some correctness check to ensure kthread_bind() is always called before the first kthread wake up. - Default affine kthread to its preferred node. - Convert kswapd / kcompactd and remove their halfway working ad-hoc affinity implementation - Implement kthreads preferred affinity - Unify kthread worker and kthread API's style - Convert RCU kthreads to the new API and remove the ad-hoc affinity implementation" * tag 'kthread-for-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks: kthread: modify kernel-doc function name to match code rcu: Use kthread preferred affinity for RCU exp kworkers treewide: Introduce kthread_run_worker[_on_cpu]() kthread: Unify kthread_create_on_cpu() and kthread_create_worker_on_cpu() automatic format rcu: Use kthread preferred affinity for RCU boost kthread: Implement preferred affinity mm: Create/affine kswapd to its preferred node mm: Create/affine kcompactd to its preferred node kthread: Default affine kthread to its preferred NUMA node kthread: Make sure kthread hasn't started while binding it sched,arm64: Handle CPU isolation on last resort fallback rq selection arm64: Exclude nohz_full CPUs from 32bits el0 support lib: test_objpool: Use kthread_run_on_cpu() kallsyms: Use kthread_run_on_cpu() soc/qman: test: Use kthread_run_on_cpu() arm/bL_switcher: Use kthread_run_on_cpu()
| * | treewide: Introduce kthread_run_worker[_on_cpu]()Frederic Weisbecker2025-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kthread_create() creates a kthread without running it yet. kthread_run() creates a kthread and runs it. On the other hand, kthread_create_worker() creates a kthread worker and runs it. This difference in behaviours is confusing. Also there is no way to create a kthread worker and affine it using kthread_bind_mask() or kthread_affine_preferred() before starting it. Consolidate the behaviours and introduce kthread_run_worker[_on_cpu]() that behaves just like kthread_run(). kthread_create_worker[_on_cpu]() will now only create a kthread worker without starting it.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With KASAN enabled, clang fails to optimize the inline version of vdec_vp9_slice_map_counts_eob_coef() properly, leading to kilobytes of temporary values spilled to the stack: drivers/media/platform/mediatek/vcodec/decoder/vdec/vdec_vp9_req_lat_if.c:1526:12: error: stack frame size (2160) exceeds limit (2048) in 'vdec_vp9_slice_update_prob' [-Werror,-Wframe-larger-than] This seems to affect all versions of clang including the latest (clang-20), but the degree of stack overhead is different per release. Marking the function as noinline_for_stack is harmless here and avoids the problem completely.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The media_entity_pads_init() function was previously hardcoded to use a magic number for the number of pads.
