2024-02-26selftests: mptcp: diag: change timeout_poll to 30Geliang Tang
Even if it is set to 100ms from the beginning with commit df62f2ec3df6 ("selftests/mptcp: add diag interface tests"), there is no reason not to have it to 30ms like all the other tests. "diag.sh" is not supposed to be slower than the other ones. To maintain consistency with other scripts, this patch changes it to 30.

2024-02-26selftests: mptcp: lib: catch duplicated subtest entriesMatthieu Baerts (NGI0)
It is important to have a unique (sub)test name in TAP, because some CI environments drop tests with duplicated name. When adding a new subtest entry, an error message is printed in case of duplicated entries. If there were duplicated entries and if all features were expected to work, the script exits with an error at the end, after having printed all subtests in the TAP format. Thanks to that, the MPTCP CI will catch such issues early.

2024-02-26selftests: mptcp: explicitly trigger the listener diag code-pathPaolo Abeni
The mptcp diag interface already experienced a few locking bugs that lockdep and appropriate coverage have detected in advance. Let's add a test-case triggering the relevant code path, to prevent similar issues in the future. Be careful to cope with very slow environments. Note that we don't need an explicit timeout on the mptcp_connect subprocess to cope with eventual bug/hang-up as the final cleanup terminating the child processes will take care of that.

2024-02-26drm/edid/firmware: Remove built-in EDIDsMaxime Ripard
The EDID firmware loading mechanism introduced a few built-in EDIDs that could be forced on any connector, bypassing the EDIDs it exposes. While convenient, this limited set of EDIDs doesn't take into account the connector type, and we can end up with an EDID that is completely invalid for a given connector. For example, the edid/800x600.bin file matches the following EDID: edid-decode (hex): 00 ff ff ff ff ff ff 00 31 d8 00 00 00 00 00 00 05 16 01 03 6d 1b 14 78 ea 5e c0 a4 59 4a 98 25 20 50 54 01 00 00 45 40 01 01 01 01 01 01 01 01 01 01 01 01 01 01 a0 0f 20 00 31 58 1c 20 28 80 14 00 15 d0 10 00 00 1e 00 00 00 ff 00 4c 69 6e 75 78 20 23 30 0a 20 20 20 20 00 00 00 fd 00 3b 3d 24 26 05 00 0a 20 20 20 20 20 20 00 00 00 fc 00 4c 69 6e 75 78 20 53 56 47 41 0a 20 20 00 c2 ---------------- Block 0, Base EDID: EDID Structure Version & Revision: 1.3 Vendor & Product Identification: Manufacturer: LNX Model: 0 Made in: week 5 of 2012 Basic Display Parameters & Features: Analog display Signal Level Standard: 0.700 : 0.000 : 0.700 V p-p Blank level equals black level Sync: Separate Composite Serration Maximum image size: 27 cm x 20 cm Gamma: 2.20 DPMS levels: Standby Suspend Off RGB color display First detailed timing is the preferred timing Color Characteristics: Red : 0.6416, 0.3486 Green: 0.2919, 0.5957 Blue : 0.1474, 0.1250 White: 0.3125, 0.3281 Established Timings I & II: DMT 0x09: 800x600 60.316541 Hz 4:3 37.879 kHz 40.000000 MHz Standard Timings: DMT 0x09: 800x600 60.316541 Hz 4:3 37.879 kHz 40.000000 MHz Detailed Timing Descriptors: DTD 1: 800x600 60.316541 Hz 4:3 37.879 kHz 40.000000 MHz (277 mm x 208 mm) Hfront 40 Hsync 128 Hback 88 Hpol P Vfront 1 Vsync 4 Vback 23 Vpol P Display Product Serial Number: 'Linux #0' Display Range Limits: Monitor ranges (GTF): 59-61 Hz V, 36-38 kHz H, max dotclock 50 MHz Display Product Name: 'Linux SVGA' Checksum: 0xc2 So, an analog monitor EDID. However, if the connector was an HDMI monitor for example, it breaks the HDMI specification that requires, among other things, a digital display, the VIC 1 mode and an HDMI Forum Vendor Specific Data Block in an CTA-861 extension. We thus end up with a completely invalid EDID, which thus might confuse HDMI-related code that could parse it. After some discussions on IRC, we identified mainly two ways to fix this: - We can either create more EDIDs for each connector type to provide a built-in EDID that matches the resolution passed in the name, and still be a sensible EDID for that connector type; - Or we can just prevent the EDID to be exposed to userspace if it's built-in. Or possibly both. However, the conclusion was that maybe we just don't need the built-in EDIDs at all and we should just get rid of them. So here we are.

http://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: 1st set of new device support, features and cleanup for 6.9 IIO Backend support =================== New approach from Nuno Sa to the problem of reuse of drivers with IIO devices that are actually the combination of a highspeed chip and an FPGA core handling the data capture and flows. It will hopefully also apply to some other split designs. The ad9467 and axi-adi drivers are converted over to this framework. New device support ================== adi,admfm2000 - New driver for this dual microwave down converter. ams,as73211 - Add support for as7331 UV sensor. richtek,rtq6056 - Add support for related parts RTQ6053 and RTQ6059 st,lsm6dsx - Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs) ti,ads1298 - New driver for this medical ADC. Features ======== tests - Unit tests for the gain-time-scale helper library. bosch,bmi088 - I2C support. bosh,bmi160 - Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed. The ID is actually a PCI ID belonging to realtech. No response was received to earlier attempts to notify them of this. The manufacturers of some devices have replied to say they will not fix this incorrect ID. Add the ID and hope it isn't a problem. bosch,bmi323 - Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150 driver (it appears these parts share a windows driver). Both drivers perform an ID check that is safe on the other part before successfully probing. hid-sensors-als - Add color temperature and chromaticity support. Note this is a replacement for the series reverted in 6.8 that correctly handles all the potential channel combinations. honeywell,hsc030pa - Triggered buffer support (after driver cleanup). honeywell,mprls00025pa - Improved error handling. - New DT binding to allow use of part number triplet as provided in data sheet to specify equivalent of most of the binding more efficiently. - SPI support. memsic,mxc4005 - ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023 ti,hdc3020 - Add threshold event support (after some driver cleanup) veml,vcnl4000 - Switch to high resolution proximity measurement. Cleanup ======= Various minor typo fixes and better use of defines etc. Treewide - Stop using ACPI_PTR(). The savings in space are small and not worth the complexity of __maybe_unused of ifdef guards. To avoid use in new IIO drivers based on copy and paste, clean it out. - cleanup.h based handling of iio_device_claim_direct_mode()/ iio_device_release_direct_mode() using scope_cond_guard().

git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl Pull cxl fixes from Dan Williams: "A collection of significant fixes for the CXL subsystem. The largest change in this set, that bordered on "new development", is the fix for the fact that the location of the new qos_class attribute did not match the Documentation. The fix ends up deleting more code than it added, and it has a new unit test to backstop basic errors in this interface going forward. So the "red-diff" and unit test saved the "rip it out and try again" response. In contrast, the new notification path for firmware reported CXL errors (CXL CPER notifications) has a locking context bug that can not be fixed with a red-diff. Given where the release cycle stands, it is not comfortable to squeeze in that fix in these waning days. So, that receives the "back it out and try again later" treatment. There is a regression fix in the code that establishes memory NUMA nodes for platform CXL regions. That has an ack from x86 folks. There are a couple more fixups for Linux to understand (reassemble) CXL regions instantiated by platform firmware. The policy around platforms that do not match host-physical-address with system-physical-address (i.e. systems that have an address translation mechanism between the address range reported in the ACPI CEDT.CFMWS and endpoint decoders) has been softened to abort driver load rather than teardown the memory range (can cause system hangs). Lastly, there is a robustness / regression fix for cases where the driver would previously continue in the face of error, and a fixup for PCI error notification handling. Summary: - Fix NUMA initialization from ACPI CEDT.CFMWS - Fix region assembly failures due to async init order - Fix / simplify export of qos_class information - Fix cxl_acpi initialization vs single-window-init failures - Fix handling of repeated 'pci_channel_io_frozen' notifications - Workaround platforms that violate host-physical-address == system-physical address assumptions - Defer CXL CPER notification handling to v6.9" * tag 'cxl-fixes-6.8-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/acpi: Fix load failures due to single window creation failure acpi/ghes: Remove CXL CPER notifications cxl/pci: Fix disabling memory if DVSEC CXL Range does not match a CFMWS window cxl/test: Add support for qos_class checking cxl: Fix sysfs export of qos_class for memdev cxl: Remove unnecessary type cast in cxl_qos_class_verify() cxl: Change 'struct cxl_memdev_state' *_perf_list to single 'struct cxl_dpa_perf' cxl/region: Allow out of order assembly of autodiscovered regions cxl/region: Handle endpoint decoders in cxl_region_find_decoder() x86/numa: Fix the sort compare func used in numa_fill_memblks() x86/numa: Fix the address overlap check in numa_fill_memblks() cxl/pci: Skip to handle RAS errors if CXL.mem device is detached

2024-02-23perf print-events: make is_event_supported() more robustMark Rutland
Currently the perf tool doesn't detect support for extended event types on Apple M1/M2 systems, and will not auto-expand plain PERF_EVENT_TYPE hardware events into per-PMU events. This is due to the detection of extended event types not handling mandatory filters required by the M1/M2 PMU driver. PMU drivers and the core perf_events code can require that perf_event_attr::exclude_* filters are configured in a specific way and may reject certain configurations of filters, for example: (a) Many PMUs lack support for any event filtering, and require all perf_event_attr::exclude_* bits to be clear. This includes Alpha's CPU PMU, and ARM CPU PMUs prior to the introduction of PMUv2 in ARMv7, (b) When /proc/sys/kernel/perf_event_paranoid >= 2, the perf core requires that perf_event_attr::exclude_kernel is set. (c) The Apple M1/M2 PMU requires that perf_event_attr::exclude_guest is set as the hardware PMU does not count while a guest is running (but might be extended in future to do so). In is_event_supported(), we try to account for cases (a) and (b), first attempting to open an event without any filters, and if this fails, retrying with perf_event_attr::exclude_kernel set. We do not account for case (c), or any other filters that drivers could theoretically require to be set. Thus is_event_supported() will fail to detect support for any events targeting an Apple M1/M2 PMU, even where events would be supported with perf_event_attr:::exclude_guest set. Since commit: 82fe2e45cdb00de4 ("perf pmus: Check if we can encode the PMU number in perf_event_attr.type") ... we use is_event_supported() to detect support for extended types, with the PMU ID encoded into the perf_event_attr::type. As above, on an Apple M1/M2 system this will always fail to detect that the event is supported, and consequently we fail to detect support for extended types even when these are supported, as they have been since commit: 5c816728651ae425 ("arm_pmu: Add PERF_PMU_CAP_EXTENDED_HW_TYPE capability") Due to this, the perf tool will not automatically expand plain PERF_TYPE_HARDWARE events into per-PMU events, even when all the necessary kernel support is present. This patch updates is_event_supported() to additionally try opening events with perf_event_attr::exclude_guest set, allowing support for events to be detected on Apple M1/M2 systems. I believe that this is sufficient for all contemporary CPU PMU drivers, though in future it may be necessary to check for other combinations of filter bits. I've deliberately changed the check to not expect a specific error code for missing filters, as today ;the kernel may return a number of different error codes for missing filters (e.g. -EACCESS, -EINVAL, or -EOPNOTSUPP) depending on why and where the filter configuration is rejected, and retrying for any error is more robust. Note that this does not remove the need for commit: a24d9d9dc096fc0d ("perf parse-events: Make legacy events lower priority than sysfs/JSON") ... which is still necessary so that named-pmu/event/ events work on kernels without extended type support, even if the event name happens to be the same as a PERF_EVENT_TYPE_HARDWARE event (e.g. as is the case for the M1/M2 PMU's 'cycles' and 'instructions' events).
