There is no mutex protection of these state checking for 'stop' and 'detach' which can't guarantee there is no another instance is trying to do same operation. Consider two instances case: Instance1: echo stop > /sys/class/remoteproc/remoteproc0/state Instance2: echo stop > /sys/class/remoteproc/remoteproc0/state The issue is that the instance2 case may success, Or it may fail with -EINVAL, which is uncertain. So move this state checking in rproc_cdev_write() and state_store() for 'stop', 'detach' operation to 'rproc_shutdown' , 'rproc_detach' function under the mutex protection.

There is no mutex protection of the state checking before rproc_boot(), which can't guarantee there is no another instance is trying to do same operation. Consider two instances case: Instance1: echo start > /sys/class/remoteproc/remoteproc0/state Instance2: echo start > /sys/class/remoteproc/remoteproc0/state ... Instance2: echo stop > /sys/class/remoteproc/remoteproc0/state ... Instance1: echo stop > /sys/class/remoteproc/remoteproc0/state The one issue is that the instance2 case may success when 'start' happens at same time as instance1, then rproc->power = 2; Or it may fail with -BUSY, then rproc->power = 1; which is uncertain. The another issue is for 'stop' operation, if the rproc->power = 1, when instance2 'stop' the remoteproc the instance1 will be impacted for it still needs the service at that time. The reference counter rproc->power is used to manage state changing and there is mutex protection in each operation function for multi instance case. So remove this state checking in rproc_cdev_write() and state_store() for 'start' operation, just let reference counter rproc->power to manage the behaviors.

The definition of L1TCM_SRAM_PDN bits on mt8195 is different to mt8192. L1TCM_SRAM_PDN bits[3:0] control the power of mt8195 L1TCM SRAM. L1TCM_SRAM_PDN bits[7:4] control the access path to EMI for SCP. These bits have to be powered on to allow EMI access for SCP. Bits[7:4] also affect audio DSP because audio DSP and SCP are placed on the same hardware bus. If SCP cannot access EMI, audio DSP is blocked too. L1TCM_SRAM_PDN bits[31:8] are not used. This fix removes modification of bits[7:4] when power on/off mt8195 SCP L1TCM. It's because the modification introduces a short period of time blocking audio DSP to access EMI. This was not a problem until we have to load both SCP module and audio DSP module. audio DSP needs to access EMI because it has source/data on DRAM. Audio DSP will have unexpected behavior when it accesses EMI and the SCP driver blocks the EMI path at the same time.

I had to wait until after 5.18-rc1 for all of the changes to do this came in through different development trees, and then one new user snuck in. So this series has two changes: - removal of the default_attrs field in the powerpc/pseries/vas code. The change has been acked by the PPC maintainers to come through this tree - removal of default_attrs from struct kobj_type now that all in-kernel users are removed.

The 'perf bench epoll' testcase fails on systems with more than 1K CPUs. Testcase: perf bench epoll all Result snippet: <<>> Run summary [PID 106497]: 1399 threads monitoring on 64 file-descriptors for 8 secs. perf: pthread_create: No such file or directory <<>> In epoll benchmarks (ctl, wait) pthread_create is invoked in do_threads from respective bench_epoll_* function. Though the logs shows direct failure from pthread_create, the actual failure is from "sched_setaffinity" returning EINVAL (invalid argument). This happens because the default mask size in glibc is 1024. To overcome this 1024 CPUs mask size limitation of cpu_set_t, change the mask size using the CPU_*_S macros. Patch addresses this by fixing all the epoll benchmarks to use CPU_ALLOC to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the mask.

The 'perf bench futex' testcase fails on systems with more than 1K CPUs. Testcase: perf bench futex all Failure snippet: <<>>Running futex/hash benchmark... perf: pthread_create: No such file or directory <<>> All the futex benchmarks (ie hash, lock-api, requeue, wake, wake-parallel), pthread_create is invoked in respective bench_futex_* function. Though the logs shows direct failure from pthread_create, strace logs showed that actual failure is from "sched_setaffinity" returning EINVAL (invalid argument). This happens because the default mask size in glibc is 1024. To overcome this 1024 CPUs mask size limitation of cpu_set_t, change the mask size using the CPU_*_S macros. Patch addresses this by fixing all the futex benchmarks to use CPU_ALLOC to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the mask.

Since commit bb30acae ("perf report: Bail out --mem-mode if mem info is not available") "perf mem report" and "perf report --mem-mode" don't allow opening the file unless one of the events has PERF_SAMPLE_DATA_SRC set. SPE doesn't have this set even though synthetic memory data is generated after it is decoded. Fix this issue by setting DATA_SRC on SPE events. This has no effect on the data collected because the SPE driver doesn't do anything with that flag and doesn't generate samples.

Commit Fixes: b9f6fbb3 ("perf arm64: Inject missing frames when using 'perf record --call-graph=fp'") intended to add a 'best effort' DWARF unwind that improved the frame pointer stack in most scenarios. It's expected that the unwind will fail sometimes, but this shouldn't be reported as an error. It only works when the return address can be determined from the contents of the link register alone. Fix the error shown when the unwinder requires extra registers by adding a new flag that suppresses error messages. This flag is not set in the normal --call-graph=dwarf unwind mode so that behavior is not changed.
