2024-05-08PM / devfreq: rk3399_dmc: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2024-05-08nvmet-rdma: fix possible bad dereference when freeing rspsSagi Grimberg
It is possible that the host connected and saw a cm established event and started sending nvme capsules on the qp, however the ctrl did not yet see an established event. This is why the rsp_wait_list exists (for async handling of these cmds, we move them to a pending list). Furthermore, it is possible that the ctrl cm times out, resulting in a connect-error cm event. in this case we hit a bad deref [1] because in nvmet_rdma_free_rsps we assume that all the responses are in the free list. We are freeing the cmds array anyways, so don't even bother to remove the rsp from the free_list. It is also guaranteed that we are not racing anything when we are releasing the queue so no other context accessing this array should be running.

2024-05-08nvmet: prevent sprintf() overflow in nvmet_subsys_nsid_exists()Dan Carpenter
The nsid value is a u32 that comes from nvmet_req_find_ns(). It's endian data and we're on an error path and both of those raise red flags. So let's make this safer. 1) Make the buffer large enough for any u32. 2) Remove the unnecessary initialization. 3) Use snprintf() instead of sprintf() for even more safety. 4) The sprintf() function returns the number of bytes printed, not counting the NUL terminator. It is impossible for the return value to be <= 0 so delete that.

2024-05-08thermal: intel: hfi: Increase the number of CPU capabilities per netlink eventRicardo Neri
The number of updated CPU capabilities per netlink event is hard-coded to 16. On systems with more than 16 CPUs (a common case), it takes more than one thermal netlink event to relay all the new capabilities after an HFI interrupt. This adds unnecessary overhead to both the kernel and user space entities. Increase the number of CPU capabilities updated per event to 64. Any system with 64 CPUs or less can now update all the capabilities in a single thermal netlink event.

2024-05-08thermal: intel: hfi: Shorten the thermal netlink event delay to 100msRicardo Neri
The delay between an HFI interrupt and its corresponding thermal netlink event has so far been hard-coded to CONFIG_HZ jiffies (1 second). This delay is too long for hardware that generates updates every tens of milliseconds. The HFI driver uses a delayed workqueue to send thermal netlink events. No subsequent events will be sent if there is pending work. As a result, much of the information of consecutive hardware updates will be lost if the workqueue delay is too long. User space entities may act on obsolete data. If the delay is too short, multiple events may overwhelm listeners. Set the delay to 100ms to strike a balance between too many and too few events. Use milliseconds instead of jiffies to improve readability. Signed-off-by: Ricardo Neri <ricardo.neri-calderon@linux.intel.com> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Rafael J.

2024-05-08cpufreq: amd-pstate: fix the highest frequency issue which limits performancePerry Yuan
To address the performance drop issue, an optimization has been implemented. The incorrect highest performance value previously set by the low-level power firmware for AMD CPUs with Family ID 0x19 and Model ID ranging from 0x70 to 0x7F series has been identified as the cause. To resolve this, a check has been implemented to accurately determine the CPU family and model ID. The correct highest performance value is now set and the performance drop caused by the incorrect highest performance value are eliminated. Before the fix, the highest frequency was set to 4200MHz, now it is set to 4971MHz which is correct.

2024-05-08net: stmmac: dwmac-ipq806x: account for rgmii-txid/rxid/id phy-modeChristian Marangi
Currently the ipq806x dwmac driver is almost always used attached to the CPU port of a switch and phy-mode was always set to "rgmii" or "sgmii". Some device came up with a special configuration where the PHY is directly attached to the GMAC port and in those case phy-mode needs to be set to "rgmii-id" to make the PHY correctly work and receive packets. Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id" (or variants) mode is set, the mode is rejected and probe fails. Add support also for these phy-modes to correctly setup PHYs that requires delay applied to tx/rx.

The embedded PHYs of the 88E6250 family switches are very basic - they do not even have an Extended Address / Page register. This adds support for the PHYs to the driver to set up PHY interrupts and retrieve error stats. To deal with PHYs without a page register, "simple" variants of all stat handling functions are introduced. The code should work with all 88E6250 family switches (6250/6220/6071/ 6070/6020). The PHY ID 0x01410db0 was read from a 88E6020, under the assumption that all switches of this family use the same ID. The spec only lists the prefix 0x01410c00 and leaves the last 10 bits as reserved, but that seems too unspecific to be useful, as it would cover several existing PHY IDs already supported by the driver; therefore, the ID read from the actual hardware is used.

Commit 1f2bcb8c8ccd ("gpio: protect the descriptor label with SRCU") caused a massive drop in performance of requesting GPIO lines due to the call to synchronize_srcu() on each label change. Rework the code to not wait until all read-only users are done with reading the label but instead atomically replace the label pointer and schedule its release after all read-only critical sections are done. To that end wrap the descriptor label in a struct that also contains the rcu_head struct required for deferring tasks using call_srcu() and stop using kstrdup_const() as we're required to allocate memory anyway. Just allocate enough for the label string and rcu_head in one go.

2024-05-07nvmet: make nvmet_wq unboundSagi Grimberg
When deleting many controllers one-by-one, it takes a very long time as these work elements may serialize as they are scheduled on the executing cpu instead of spreading. In general nvmet_wq can definitely be used for long standing work elements so its better to make it unbound regardless.

2024-05-07nvme-pci: Add quirk for broken MSIsSean Anderson
Sandisk SN530 NVMe drives have broken MSIs. On systems without MSI-X support, all commands time out resulting in the following message: nvme nvme0: I/O tag 12 (100c) QID 0 timeout, completion polled These timeouts cause the boot to take an excessively-long time (over 20 minutes) while the initial command queue is flushed. Address this by adding a quirk for drives with buggy MSIs.

2024-05-07drm/i915/bios: Fix parsing backlight BDB dataKarthikeyan Ramasubramanian
Starting BDB version 239, hdr_dpcd_refresh_timeout is introduced to backlight BDB data. Commit 700034566d68 ("drm/i915/bios: Define more BDB contents") updated the backlight BDB data accordingly. This broke the parsing of backlight BDB data in VBT for versions 236 - 238 (both inclusive) and hence the backlight controls are not responding on units with the concerned BDB version. backlight_control information has been present in backlight BDB data from at least BDB version 191 onwards, if not before. Hence this patch extracts the backlight_control information for BDB version 191 or newer. Tested on Chromebooks using Jasperlake SoC (reports bdb->version = 236). Tested on Chromebooks using Raptorlake SoC (reports bdb->version = 251). v2: removed checking the block size of the backlight BDB data [vsyrjala: this is completely safe thanks to commit e163cfb4c96d ("drm/i915/bios: Make copies of VBT data blocks")] Fixes: 700034566d68 ("drm/i915/bios: Define more BDB contents") Cc: stable@vger.kernel.org Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Karthikeyan Ramasubramanian <kramasub@chromium.org> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240221180622.v2.1.I0690aa3e96a83a43b3fc33f50395d334b2981826@changeid Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> (cherry picked from commit c286f6a973c66c0d993ecab9f7162c790e7064c8) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

This tablets gets a lot of things wrong: - the secondary button is reported through Secondary Tip Switch - the third button is reported through Invert Fortunately, before entering eraser mode, (so Invert = 1), the tablet always sends an out-of-proximity event. So we can detect that single event and: - if there was none but the invert bit was toggled: this is the third button - if there was this out-of-proximity event, we are entering eraser mode, and we will until the next out-of-proximity.

2024-05-07HID: bpf: add in-tree HID-BPF fix for the XBox Elite 2 over BluetoothBenjamin Tissoires
When using the XBox Wireless Controller Elite 2 over Bluetooth, the device exports the paddle on the back of the device as a single bitfield value of usage "Assign Selection". The kernel doesn't process those usages properly and report KEY_UNKNOWN for it. SDL doesn't know how to interprete that KEY_UNKNOWN and thus ignores the paddles. Given that over USB the kernel uses BTN_TRIGGER_HAPPY[5-8], we can tweak the report descriptor to make the kernel interprete it properly: - we need an application collection of gamepad (so we have to close the current Consumer Control one) - we need to change the usage to be buttons from 0x15 to 0x18 Link: https://lore.kernel.org/r/20240410-bpf_sources-v1-7-a8bf16033ef8@kernel.org Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Benjamin Tissoires <bentiss@kernel.org>
2024-05-07HID: bpf: add in-tree HID-BPF fix for the Wacom ArtPenBenjamin Tissoires
This pen is compatible with multiple Wacom tablets, but we only add support for the Intuos Pro 2 M, as this is the one our user reported the bug against. We can not generically add all compatible Wacom tablets as we are writing the offsets by hand. The point of this HID-BPF program is to work around a firmware limitation where the pressure is repeated every other report. Given that we know this will happen, we can change the first new pressure information with the mean compared to the previous one. This way we smooth the incoming pressure without losing information.

This commit adds a fix for XPPen Artist 24 where the second button on the pen is used as an eraser. It's a "feature" from Microsoft, but it turns out that it's actually painful for artists. So we ship here a HID-BPF program that turns this second button into an actual button. Note that the HID-BPF program is not directly loaded by the kernel itself but by udev-hid-bpf[0]. But having the sources here allows us to also integrate tests into tools/testing/selftests/hid to ensure the HID-BPF program are actually tested.

This reverts commit 3f9f231236ce7e48780d8a4f1f8cb9fae2df1e4e. Using 64bit for 'sync_io' is unnecessary from the gendisk side. This overflow will not cause any functional impact, except for a UBSAN warning. Solving this overflow requires introducing additional calculations and checks which are not necessary. So just keep using 32bit for 'sync_io'.
