2023-08-07net/mlx5: Allocate completion EQs dynamicallyMaher Sanalla1-1/+1
This commit enables the dynamic allocation of EQs at runtime, allowing for more flexibility in managing completion EQs and reducing the memory overhead of driver load. Whenever a CQ is created for a given vector index, the driver will lookup to see if there is an already mapped completion EQ for that vector, if so, utilize it. Otherwise, allocate a new EQ on demand and then utilize it for the CQ completion events. Add a protection lock to the EQ table to protect from concurrent EQ creation attempts. While at it, replace mlx5_vector2irqn()/mlx5_vector2eqn() with mlx5_comp_eqn_get() and mlx5_comp_irqn_get() which will allocate an EQ on demand if no EQ is found for the given vector.

2023-08-07net/mlx5: Add IRQ vector to CPU lookup functionMaher Sanalla1-2/+1
Currently, once driver load completes, IRQ requests were performed for all vectors. However, as we move to support dynamic creation of EQs, this will not be the case as some IRQs will not exist at this stage. Thus, in such case, use the default CPU to IRQ mapping which is the serial mapping based on IRQ vector index. Meaning, the n'th vector gets mapped to the n'th CPU. Introduce an API function mlx5_comp_vector_cpu() that takes an IRQ index and provides the corresponding CPU mapping. It utilizes the existing IRQ affinity if defined, or resorts to the default serialized CPU mapping otherwise.

2023-08-06vfs: get rid of old '->iterate' directory operationLinus Torvalds1-1/+7
All users now just use '->iterate_shared()', which only takes the directory inode lock for reading. Filesystems that never got convered to shared mode now instead use a wrapper that drops the lock, re-takes it in write mode, calls the old function, and then downgrades the lock back to read mode. This way the VFS layer and other callers no longer need to care about filesystems that never got converted to the modern era. The filesystems that use the new wrapper are ceph, coda, exfat, jfs, ntfs, ocfs2, overlayfs, and vboxsf. Honestly, several of them look like they really could just iterate their directories in shared mode and skip the wrapper entirely, but the point of this change is to not change semantics or fix filesystems that haven't been fixed in the last 7+ years, but to finally get rid of the dual iterators.

Group some variables based on their sizes to reduce hole and avoid padding. On x86_64, this shrinks the size of 'struct kobject' from 256 to 244 bytes. This structure is often included in some other structures. So these other structures will also benefit from this 8 bytes saving. This is especially nice for structure like 'cma_kobject' or 'class_dir' that are now 256 bytes long. When they are kzalloc()'ed, 256 bytes are allocated, instead of 512.

This commit provides the interfaces for the new UAPI motivated by the Vulkan API. It allows user mode drivers (UMDs) to: 1) Initialize a GPU virtual address (VA) space via the new DRM_IOCTL_NOUVEAU_VM_INIT ioctl. UMDs can provide a kernel reserved VA area. 2) Bind and unbind GPU VA space mappings via the new DRM_IOCTL_NOUVEAU_VM_BIND ioctl. 3) Execute push buffers with the new DRM_IOCTL_NOUVEAU_EXEC ioctl. Both, DRM_IOCTL_NOUVEAU_VM_BIND and DRM_IOCTL_NOUVEAU_EXEC support asynchronous processing with DRM syncobjs as synchronization mechanism. The default DRM_IOCTL_NOUVEAU_VM_BIND is synchronous processing, DRM_IOCTL_NOUVEAU_EXEC supports asynchronous processing only.

2023-08-04drm/gem: fix lockdep check for dma-resv lockDanilo Krummrich1-6/+9
When no custom lock is set to protect a GEMs GPUVA list, lockdep checks should fall back to the GEM objects dma-resv lock. With the current implementation we're setting the lock_dep_map of the GEM objects 'resv' pointer (in case no custom lock_dep_map is set yet) on drm_gem_private_object_init(). However, the GEM objects 'resv' pointer might still change after drm_gem_private_object_init() is called, e.g. through ttm_bo_init_reserved(). This can result in the wrong lock being tracked. To fix this, call dma_resv_held() directly from drm_gem_gpuva_assert_lock_held() and fall back to the GEMs lock_dep_map pointer only if an actual custom lock is set.

2023-08-04dyndbg: add source filename to prefixThomas Weißschuh1-1/+3
Printing the line number without the file is of limited usefulness. Knowing the filename also makes it also easier to relate the logged information to the controlfile. Example: # modprobe test_dynamic_debug # echo 'file test_dynamic_debug.c =pfsl' > /proc/dynamic_debug/control # echo 1 > /sys/module/test_dynamic_debug/parameters/do_prints # dmesg | tail -2 [ 71.802212] do_cats:lib/test_dynamic_debug.c:103: test_dd: doing categories [ 71.802227] do_levels:lib/test_dynamic_debug.c:123: test_dd: doing levels Signed-off-by: Thomas Weißschuh <[email protected]> Acked-by: Jim Cromie <[email protected]> Acked-by: Jason Baron <[email protected]> Reviewed-by: Luis Chamberlain <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>

vlan_insert_tag() and friends do not allocate a new skb. However they might allocate a new skb->head. Update their comments to better describe their behavior.

2023-08-04tcp/dccp: cache line align inet_hashinfoEric Dumazet1-1/+1
I have seen tcp_hashinfo starting at a non optimal location, forcing input handlers to pull two cache lines instead of one, and sharing a cache line that was dirtied more than necessary: ffffffff83680600 b tcp_orphan_timer ffffffff83680628 b tcp_orphan_cache ffffffff8368062c b tcp_enable_tx_delay.__tcp_tx_delay_enabled ffffffff83680630 B tcp_hashinfo ffffffff83680680 b tcp_cong_list_lock After this patch, ehash, ehash_locks, ehash_mask and ehash_locks_mask are located in a read-only cache line.

2023-08-04net: mana: Configure hwc timeout from hardwareSouradeep Chakrabarti2-1/+24
At present hwc timeout value is a fixed value. This patch sets the hwc timeout from the hardware. It now uses a new hardware capability GDMA_DRV_CAP_FLAG_1_HWC_TIMEOUT_RECONFIG to query and set the value in hwc_timeout.

2023-08-04bus: mhi: host: allow MHI client drivers to provide the firmware via a pointerKalle Valo1-0/+6
Currently MHI loads the firmware image from the path provided by client devices. ath11k needs to support firmware image embedded along with meta data (named as firmware-2.bin). So allow the client driver to request the firmware file from user space on it's own and provide the firmware image data and size to MHI via a pointer struct mhi_controller::fw_data. This is an optional feature, if fw_data is NULL MHI load the firmware using the name from struct mhi_controller::fw_image string as before. Tested with ath11k and WCN6855 hw2.0.
