2022-07-04ARM: dts: stm32: use the correct clock source for CEC on stm32mp151Gabriel Fernandez1-1/+1
The peripheral clock of CEC is not LSE but CEC. Signed-off-by: Gabriel Fernandez <gabriel.fernandez@foss.st.com> Signed-off-by: Alexandre Torgue <alexandre.torgue@foss.st.com>
2022-07-04ARM: dts: stm32: fix pwr regulators references to use scmiEtienne Carriere3-0/+54
Fixes stm32mp15*-scmi DTS files introduced in [1] to also access PWR regulators through SCMI service. This is needed since enabling secure only access to RCC clock and reset controllers also enables secure access only on PWR voltage regulators reg11, reg18 and usb33 hence these must also be accessed through SCMI Voltage Domain protocol. This change applies on commit [2] that already corrects issues from commit [1].

2022-06-26parisc: Enable ARCH_HAS_STRICT_MODULE_RWXHelge Deller1-0/+1
Fix a boot crash on a c8000 machine as reported by Dave. Basically it changes patch_map() to return an alias mapping to the to-be-patched code in order to prevent writing to write-protected memory.

2022-06-26parisc: Fix flush_anon_page on PA8800/PA8900John David Anglin1-1/+4
Anonymous pages are allocated with the shared mappings colouring, SHM_COLOUR. Since the alias boundary on machines with PA8800 and PA8900 processors is unknown, flush_user_cache_page() might not flush all mappings of a shared anonymous page. Flushing the whole data cache flushes all mappings. This won't fix all coherency issues with shared mappings but it seems to work well in practice. I haven't seen any random memory faults in almost a month on a rp3440 running as a debian buildd machine. There is a small preformance hit.

2022-06-23s390/pai: Fix multiple concurrent event installationThomas Richter1-3/+12
Two different events such as pai_crypto/KM_AES_128/ and pai_crypto/KM_AES_192/ can be installed multiple times on the same CPU and the events are executed concurrently: # perf stat -e pai_crypto/KM_AES_128/ -C0 -a -- sleep 5 & # sleep 2 # perf stat -e pai_crypto/KM_AES_192/ -C0 -a -- true This results in the first event being installed two times with two seconds delay. The kernel does install the second event after the first event has been deleted and re-added, as can be seen in the traces: 13:48:47.600350 paicrypt_start event 0x1007 (event KM_AES_128) 13:48:49.599359 paicrypt_stop event 0x1007 (event KM_AES_128) 13:48:49.599198 paicrypt_start event 0x1007 13:48:49.599199 paicrypt_start event 0x1008 13:48:49.599921 paicrypt_event_destroy event 0x1008 13:48:52.601507 paicrypt_event_destroy event 0x1007 This is caused by functions event_sched_in() and event_sched_out() which call the PMU's add() and start() functions on schedule_in and the PMU's stop() and del() functions on schedule_out. This is correct for events attached to processes. The pai_crypto events are system-wide events and not attached to processes. Since the kernel common code can not be changed easily, fix this issue and do not reset the event count value to zero each time the event is added and started. Instead use a flag and zero the event count value only when called immediately after the event has been initialized. Therefore only the first invocation of the the event's add() function initializes the event count value to zero. The following invocations of the event's add() function leave the current event count value untouched.

2022-06-23s390/cpumf: Handle events cycles and instructions identicalThomas Richter1-1/+21
Events CPU_CYCLES and INSTRUCTIONS can be submitted with two different perf_event attribute::type values: - PERF_TYPE_HARDWARE: when invoked via perf tool predefined events name cycles or cpu-cycles or instructions. - pmu->type: when invoked via perf tool event name cpu_cf/CPU_CYLCES/ or cpu_cf/INSTRUCTIONS/. This invocation also selects the PMU to which the event belongs. Handle both type of invocations identical for events CPU_CYLCES and INSTRUCTIONS. They address the same hardware. The result is different when event modifier exclude_kernel is also set. Invocation with event modifier for user space event counting fails. Output before: # perf stat -e cpum_cf/cpu_cycles/u -- true Performance counter stats for 'true': <not supported> cpum_cf/cpu_cycles/u 0.000761033 seconds time elapsed 0.000076000 seconds user 0.000725000 seconds sys # Output after: # perf stat -e cpum_cf/cpu_cycles/u -- true Performance counter stats for 'true': 349,613 cpum_cf/cpu_cycles/u 0.000844143 seconds time elapsed 0.000079000 seconds user 0.000800000 seconds sys # Fixes: 6a82e23f45fe ("s390/cpumf: Adjust registration of s390 PMU device drivers") Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Acked-by: Sumanth Korikkar <sumanthk@linux.ibm.com> [agordeev@linux.ibm.com corrected commit ID of Fixes commit] Signed-off-by: Alexander Gordeev <agordeev@linux.ibm.com>

2022-06-22powerpc/powernv: wire up rng during setup_archJason A. Donenfeld3-16/+40
The platform's RNG must be available before random_init() in order to be useful for initial seeding, which in turn means that it needs to be called from setup_arch(), rather than from an init call. Complicating things, however, is that POWER8 systems need some per-cpu state and kmalloc, which isn't available at this stage. So we split things up into an early phase and a later opportunistic phase. This commit also removes some noisy log messages that don't add much.
