2023-03-24drm/i915/perf: Add engine class instance parameters to perfUmesh Nerlige Ramappa1-0/+19
One or more engines map to a specific OA unit. All reports from these engines are captured in the OA buffer managed by this OA unit. Current i915 OA implementation supports only the OAG unit. OAG primarily caters to render engine, so i915 OA uses render as the default engine in the OA implementation. Since there are more OA units on newer hardware that map to other engines, allow user to pass engine class and instance to select and program specific OA units.

2023-03-24cfg80211: support RNR for EMA APAloka Dixit2-0/+32
As per IEEE Std 802.11ax-2021, 11.1.3.8.3 Discovery of a nontransmitted BSSID profile, an EMA AP that transmits a Beacon frame carrying a partial list of nontransmitted BSSID profiles should include in the frame a Reduced Neighbor Report element carrying information for at least the nontransmitted BSSIDs that are not present in the Multiple BSSID element carried in that frame. Add new nested attribute NL80211_ATTR_EMA_RNR_ELEMS to support the above. Number of RNR elements must be more than or equal to the number of MBSSID elements. This attribute can be used only when EMA is enabled. Userspace is responsible for splitting the RNR into multiple elements such that each element excludes the non-transmitting profiles already included in the MBSSID element (%NL80211_ATTR_MBSSID_ELEMS) at the same index. Each EMA beacon will be generated by adding MBSSID and RNR elements at the same index. If the userspace provides more RNR elements than the number of MBSSID elements then these will be added in every EMA beacon.

2023-03-23x86,objtool: Split UNWIND_HINT_EMPTY in twoJosh Poimboeuf2-15/+22
Mark reported that the ORC unwinder incorrectly marks an unwind as reliable when the unwind terminates prematurely in the dark corners of return_to_handler() due to lack of information about the next frame. The problem is UNWIND_HINT_EMPTY is used in two different situations: 1) The end of the kernel stack unwind before hitting user entry, boot code, or fork entry 2) A blind spot in ORC coverage where the unwinder has to bail due to lack of information about the next frame The ORC unwinder has no way to tell the difference between the two. When it encounters an undefined stack state with 'end=1', it blindly marks the stack reliable, which can break the livepatch consistency model. Fix it by splitting UNWIND_HINT_EMPTY into UNWIND_HINT_UNDEFINED and UNWIND_HINT_END_OF_STACK.

A number of iommu functions take a struct bus_type * and never modify the data passed in, so make them all const * as that is what the driver core is expecting to have passed into as well. This is a step toward making all struct bus_type pointers constant in the kernel.

2023-03-23driver core: make the bus_type in struct device_driver constantGreg Kroah-Hartman1-1/+1
The pointer to struct bus_type in struct device_driver should only be pointing to something that can never change now that the driver core has fixed up the previously writable fields. So mark it as a constant pointer to enforce this and move forward with the goal of moving bus_type into read-only memory. Cc: "Rafael J.

2023-03-23driver core: bus: mark the struct bus_type for sysfs callbacks as constantGreg Kroah-Hartman2-6/+4
struct bus_type should never be modified in a sysfs callback as there is nothing in the structure to modify, and frankly, the structure is almost never used in a sysfs callback, so mark it as constant to allow struct bus_type to be moved to read-only memory.

2023-03-23driver core: bus: move dev_root out of struct bus_typeGreg Kroah-Hartman1-2/+0
Now that all accesses of dev_root is through the bus_get_dev_root() call, move the pointer out of struct bus_type and into the private dynamic structure, subsys_private. With this change, there is no modifiable portions of struct bus_type so it can be marked as a constant structure and moved to read-only memory. Cc: "Rafael J.

2023-03-23vhost_task: Allow vhost layer to use copy_processMike Christie1-0/+23
Qemu will create vhost devices in the kernel which perform network, SCSI, etc IO and management operations from worker threads created by the kthread API. Because the kthread API does a copy_process on the kthreadd thread, the vhost layer has to use kthread_use_mm to access the Qemu thread's memory and cgroup_attach_task_all to add itself to the Qemu thread's cgroups, and it bypasses the RLIMIT_NPROC limit which can result in VMs creating more threads than the admin expected. This patch adds a new struct vhost_task which can be used instead of kthreads. They allow the vhost layer to use copy_process and inherit the userspace process's mm and cgroups, the task is accounted for under the userspace's nproc count and can be seen in its process tree, and other features like namespaces work and are inherited by default.

There's a number of drivers (e.g. dw_mmc, meson-gx, mmci, sunxi) using the same mechanism and a private flag vqmmc_enabled to deal with enabling/disabling the vqmmc regulator.
