2022-09-21drm/amd/display: Fix double cursor on non-video RGB MPOLeo Li
[Why] DC makes use of layer_index (zpos) when picking the HW plane to enable HW cursor on. However, some compositors will not attach zpos information to each DRM plane. Consequently, in amdgpu, we default layer_index to 0 and do not update it. This causes said DC logic to enable HW cursor on all planes of the same layer_index, which manifests as a double cursor issue if one of the planes is scaled (and hence scaling the cursor as well). [How] Use DRM core helpers to calculate a normalized_zpos value for each drm_plane_state under each crtc, within the atomic state. This helper will first consider existing zpos values, and if identical/unset, fallback to plane ID ordering. The normalized_zpos is then passed to dc_plane_info during atomic check for later use by the cursor logic.

2022-09-21drm/amdgpu: Update PTE flags with TF enabledMukul Joshi
This patch updates the PTE flags when translate further (TF) is enabled: - With translate_further enabled, invalid PTEs can be 0. Reading consecutive invalid PTEs as 0 is considered a fault. To prevent this, ensure invalid PTEs have at least 1 bit set. - The current invalid PTE flags settings to translate a retry fault into a no-retry fault, doesn't work with TF enabled. As a result, update invalid PTE flags settings which works for both TF enabled and disabled case.

2022-09-21bpf: Gate dynptr API behind CAP_BPFKumar Kartikeya Dwivedi
This has been enabled for unprivileged programs for only one kernel release, hence the expected annoyances due to this move are low. Users using ringbuf can stick to non-dynptr APIs. The actual use cases dynptr is meant to serve may not make sense in unprivileged BPF programs. Hence, gate these helpers behind CAP_BPF and limit use to privileged BPF programs.

2022-09-21s390/vfio-ap: bypass unnecessary processing of AP resourcesTony Krowiak
It is not necessary to go through the process of validation, linking of queues to mdev and vice versa and filtering the APQNs assigned to the matrix mdev to build an AP configuration for a guest if an adapter or domain being assigned is already assigned to the matrix mdev. Likewise, it is not necessary to proceed through the process the unassignment of an adapter, domain or control domain if it is not assigned to the matrix mdev. Since it is not necessary to process assignment of a resource already assigned or process unassignment of a resource that is been assigned, this patch will bypass all assignment/unassignment operations for an adapter, domain or control domain under these circumstances. Not only is assignment of a duplicate adapter or domain unnecessary, it will also cause a hang situation when removing the matrix mdev to which it is assigned. The reason is because the same vfio_ap_queue objects with an APQN containing the APID of the adapter or APQI of the domain being assigned will get added multiple times to the hashtable that holds them. This results in the pprev and next pointers of the hlist_node (mdev_qnode field in the vfio_ap_queue object) pointing to the queue object itself resulting in an interminable loop when the mdev is removed and the queue table is iterated to reset the queues.

2022-09-21perf kcore_copy: Do not check /proc/modules is unchangedAdrian Hunter
/proc/kallsyms and /proc/modules are compared before and after the copy in order to ensure no changes during the copy. However /proc/modules also might change due to reference counts changing even though that does not make any difference. Any modules loaded or unloaded should be visible in changes to kallsyms, so it is not necessary to check /proc/modules also anyway. Remove the comparison checking that /proc/modules is unchanged.

2022-09-21libperf evlist: Fix polling of system-wide eventsAdrian Hunter
Originally, (refer commit f90d194a867a5a1d ("perf evlist: Do not poll events that use the system_wide flag") there wasn't much reason to poll system-wide events because: 1. The mmaps get "merged" via set-output anyway (the per-cpu case) 2. perf reads all mmaps when any event is woken 3. system-wide mmaps do not fill up as fast as the mmaps for user selected events But there was 1 reason not to poll which was that it prevented correct termination due to POLLHUP on all user selected events. That issue is now easily resolved by using fdarray_flag__nonfilterable. With the advent of commit ae4f8ae16a078964 ("libperf evlist: Allow mixing per-thread and per-cpu mmaps"), system-wide mmaps can be used also in the per-thread case where reason 1 does not apply. Fix the omission of system-wide events from polling by using the fdarray_flag__nonfilterable flag. Example: Before: $ perf record --no-bpf-event -vvv -e intel_pt// --per-thread uname 2>err.txt Linux $ grep 'sys_perf_event_open.*=\|pollfd' err.txt sys_perf_event_open: pid 155076 cpu -1 group_fd -1 flags 0x8 = 5 sys_perf_event_open: pid 155076 cpu -1 group_fd -1 flags 0x8 = 6 sys_perf_event_open: pid -1 cpu 0 group_fd -1 flags 0x8 = 7 sys_perf_event_open: pid -1 cpu 1 group_fd -1 flags 0x8 = 9 sys_perf_event_open: pid -1 cpu 2 group_fd -1 flags 0x8 = 10 sys_perf_event_open: pid -1 cpu 3 group_fd -1 flags 0x8 = 11 sys_perf_event_open: pid -1 cpu 4 group_fd -1 flags 0x8 = 12 sys_perf_event_open: pid -1 cpu 5 group_fd -1 flags 0x8 = 13 sys_perf_event_open: pid -1 cpu 6 group_fd -1 flags 0x8 = 14 sys_perf_event_open: pid -1 cpu 7 group_fd -1 flags 0x8 = 15 thread_data[0x55fb43c29e80]: pollfd[0] <- event_fd=5 thread_data[0x55fb43c29e80]: pollfd[1] <- event_fd=6 thread_data[0x55fb43c29e80]: pollfd[2] <- non_perf_event fd=4 After: $ perf record --no-bpf-event -vvv -e intel_pt// --per-thread uname 2>err.txt Linux $ grep 'sys_perf_event_open.*=\|pollfd' err.txt sys_perf_event_open: pid 156316 cpu -1 group_fd -1 flags 0x8 = 5 sys_perf_event_open: pid 156316 cpu -1 group_fd -1 flags 0x8 = 6 sys_perf_event_open: pid -1 cpu 0 group_fd -1 flags 0x8 = 7 sys_perf_event_open: pid -1 cpu 1 group_fd -1 flags 0x8 = 9 sys_perf_event_open: pid -1 cpu 2 group_fd -1 flags 0x8 = 10 sys_perf_event_open: pid -1 cpu 3 group_fd -1 flags 0x8 = 11 sys_perf_event_open: pid -1 cpu 4 group_fd -1 flags 0x8 = 12 sys_perf_event_open: pid -1 cpu 5 group_fd -1 flags 0x8 = 13 sys_perf_event_open: pid -1 cpu 6 group_fd -1 flags 0x8 = 14 sys_perf_event_open: pid -1 cpu 7 group_fd -1 flags 0x8 = 15 thread_data[0x55cc19e58e80]: pollfd[0] <- event_fd=5 thread_data[0x55cc19e58e80]: pollfd[1] <- event_fd=6 thread_data[0x55cc19e58e80]: pollfd[2] <- event_fd=7 thread_data[0x55cc19e58e80]: pollfd[3] <- event_fd=9 thread_data[0x55cc19e58e80]: pollfd[4] <- event_fd=10 thread_data[0x55cc19e58e80]: pollfd[5] <- event_fd=11 thread_data[0x55cc19e58e80]: pollfd[6] <- event_fd=12 thread_data[0x55cc19e58e80]: pollfd[7] <- event_fd=13 thread_data[0x55cc19e58e80]: pollfd[8] <- event_fd=14 thread_data[0x55cc19e58e80]: pollfd[9] <- event_fd=15 thread_data[0x55cc19e58e80]: pollfd[10] <- non_perf_event fd=4 Fixes: ae4f8ae16a078964 ("libperf evlist: Allow mixing per-thread and per-cpu mmaps") Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20220915122612.81738-3-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2022-09-21perf record: Fix cpu mask bit setting for mixed mmapsAdrian Hunter
With mixed per-thread and (system-wide) per-cpu maps, the "any cpu" value -1 must be skipped when setting CPU mask bits. Prior to commit cbd7bfc7fd99acdd ("tools/perf: Fix out of bound access to cpu mask array") the invalid setting went unnoticed, but since then it causes perf record to fail with an error. Example: Before: $ perf record -e intel_pt// --per-thread uname Failed to initialize parallel data streaming masks After: $ perf record -e intel_pt// --per-thread uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.068 MB perf.data ] Fixes: ae4f8ae16a078964 ("libperf evlist: Allow mixing per-thread and per-cpu mmaps") Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20220915122612.81738-2-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

It uses PERF_EVENT_IOC_MODIFY_ATTRIBUTES ioctl. The kernel would return ENOTTY if it's not supported. Update the skip reason in that case. Committer notes: On s/390 the args aren't used, so need to be marked __maybe_unused.

2022-09-21dt-bindings: memory: snps,dw-umctl2-ddrc: Extend schema with ↵Serge Semin
IRQs/resets/clocks props First of all the DW uMCTL2 DDRC IP-core supports the individual IRQ lines for each standard event: ECC Corrected Error, ECC Uncorrected Error, ECC Address Protection, Scrubber-Done signal, DFI Parity/CRC Error. It's possible that the platform engineers merge them up in the IRQ controller level. So let's add both configuration support to the DT-schema. Secondly the DW uMCTL2 DDRC IP-core can have clock sources like APB reference clock, AXI-ports clock, main DDRC core reference clock and Scrubber low-power clock. In addition to that each clock domain can have a dedicated reset signal. Let's add the properties for at least the denoted clock sources and the corresponding reset controls. Note the IRQs and the phandles order is deliberately not fixed since some of the sources may be absent depending on the IP-core synthesize parameters and the particular platform setups.

2022-09-21intel_idle: Add AlderLake-N supportZhang Rui
Similar to the other other AlderLake platforms, the C1 and C1E states on ADL-N are mutually exclusive. Only one of them can be enabled at a time. C1E is preferred on ADL-N for better energy efficiency. C6S is also supported on this platform. Its latency is far bigger than C6, but really close to C8 (PC8), thus it is not exposed as a separate state.
