2024-08-05drm/msm/dpu: move dpu_encoder's connector assignment to atomic_enable()Abhinav Kumar
For cases where the crtc's connectors_changed was set without enable/active getting toggled , there is an atomic_enable() call followed by an atomic_disable() but without an atomic_mode_set(). This results in a NULL ptr access for the dpu_encoder_get_drm_fmt() call in the atomic_enable() as the dpu_encoder's connector was cleared in the atomic_disable() but not re-assigned as there was no atomic_mode_set() call. Fix the NULL ptr access by moving the assignment for atomic_enable() and also use drm_atomic_get_new_connector_for_encoder() to get the connector from the atomic_state.

2024-08-05drm/msm/dpu: don't play tricks with debug macrosDmitry Baryshkov
DPU debugging macros need to be converted to a proper drm_debug_* macros, however this is a going an intrusive patch, not suitable for a fix. Wire DPU_DEBUG and DPU_DEBUG_DRIVER to always use DRM_DEBUG_DRIVER to make sure that DPU debugging messages always end up in the drm debug messages and are controlled via the usual drm.debug mask. I don't think that it is a good idea for a generic DPU_DEBUG macro to be tied to DRM_UT_KMS. It is used to report a debug message from driver, so by default it should go to the DRM_UT_DRIVER channel. While refactoring debug macros later on we might end up with particular messages going to ATOMIC or KMS, but DRIVER should be the default.

2024-08-05drm/mediatek: Set sensible cursor width/height values to fix crashAngeloGioacchino Del Regno
Hardware-speaking, there is no feature-reduced cursor specific plane, so this driver reserves the last all Overlay plane as a Cursor plane, but sets the maximum cursor width/height to the maximum value that the full overlay plane can use. While this could be ok, it raises issues with common userspace using libdrm (especially Mutter, but other compositors too) which will crash upon performing allocations and/or using said cursor plane. Reduce the maximum width/height for the cursor to 512x512 pixels, value taken from IGT's maximum cursor size test, which succeeds.

2024-08-05wifi: ath12k: use 128 bytes aligned iova in transmit path for WCN7850Baochen Qiang
In transmit path, it is likely that the iova is not aligned to PCIe TLP max payload size, which is 128 for WCN7850. Normally in such cases hardware is expected to split the packet into several parts in a manner such that they, other than the first one, have aligned iova. However due to hardware limitations, WCN7850 does not behave like that properly with some specific unaligned iova in transmit path. This easily results in target hang in a KPI transmit test: packet send/receive failure, WMI command send timeout etc. Also fatal error seen in PCIe level: ... Capabilities: ... ... DevSta: ... FatalErr+ ... ... ... Work around this by manually moving/reallocating payload buffer such that we can map it to a 128 bytes aligned iova. The moving requires sufficient head room or tail room in skb: for the former we can do ourselves a favor by asking some extra bytes when registering with mac80211, while for the latter we can do nothing. Moving/reallocating buffer consumes additional CPU cycles, but the good news is that an aligned iova increases PCIe efficiency. In my tests on some X86 platforms the KPI results are almost consistent. Since this is seen only with WCN7850, add a new hardware parameter to differentiate from others.

2024-08-04Input: uinput - reject requests with unreasonable number of slotsDmitry Torokhov
From: Dmitry Torokhov <dmitry.torokhov@gmail.com> When exercising uinput interface syzkaller may try setting up device with a really large number of slots, which causes memory allocation failure in input_mt_init_slots(). While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request. Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.

2024-08-04i2c: smbus: Send alert notifications to all devices if source not foundGuenter Roeck
If a SMBus alert is received and the originating device is not found, the reason may be that the address reported on the SMBus alert address is corrupted, for example because multiple devices asserted alert and do not correctly implement SMBus arbitration. If this happens, call alert handlers on all devices connected to the given I2C bus, in the hope that this cleans up the situation. This change reliably fixed the problem on a system with multiple devices on a single bus. Example log where the device on address 0x18 (ADM1021) and on address 0x4c (ADT7461A) both had the alert line asserted: smbus_alert 3-000c: SMBALERT# from dev 0x0c, flag 0 smbus_alert 3-000c: no driver alert()! smbus_alert 3-000c: SMBALERT# from dev 0x0c, flag 0 smbus_alert 3-000c: no driver alert()! lm90 3-0018: temp1 out of range, please check! lm90 3-0018: Disabling ALERT# lm90 3-0029: Everything OK lm90 3-002a: Everything OK lm90 3-004c: temp1 out of range, please check! lm90 3-004c: temp2 out of range, please check! lm90 3-004c: Disabling ALERT# Fixes: b5527a7766f0 ("i2c: Add SMBus alert support") Signed-off-by: Guenter Roeck <linux@roeck-us.net> [wsa: fixed a typo in the commit message] Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

There is a scenario where a large number of discard commands are issued when the iscsi initiator connects to the target and then performs a session rescan operation. There is a time window, most of the commands are in UNMAP mode, and some discard commands become WRITE SAME with UNMAP. The discard mode has been negotiated during the SCSI probe. If the mode is temporarily changed from UNMAP to WRITE SAME with UNMAP, an I/O ERROR may occur because the target may not implement WRITE SAME with UNMAP.

2024-08-02iommu: Restore lost return in iommu_report_device_fault()Barak Biber
When iommu_report_device_fault gets called with a partial fault it is supposed to collect the fault into the group and then return. Instead the return was accidently deleted which results in trying to process the fault and an eventual crash. Deleting the return was a typo, put it back.

2024-08-02cpufreq: intel_pstate: Update Balance performance EPP for Emerald RapidsPedro Henrique Kopper
On Intel Emerald Rapids machines, we ship the Energy Performance Preference (EPP) default for balance_performance as 128. However, during an internal investigation together with Intel, we have determined that 32 is a more suitable value. This leads to significant improvements in both performance and energy: POV-Ray: 32% faster | 12% less energy OpenSSL: 12% faster | energy within 1% Build Linux Kernel: 29% faster | 18% less energy Therefore, we should move the default EPP for balance_performance to 32. This is in line with what has already been done for Sapphire Rapids.

2024-08-02HID: wacom: Defer calculation of resolution until resolution_code is knownJason Gerecke
The Wacom driver maps the HID_DG_TWIST usage to ABS_Z (rather than ABS_RZ) for historic reasons. When the code to support twist was introduced in commit 50066a042da5 ("HID: wacom: generic: Add support for height, tilt, and twist usages"), we were careful to write it in such a way that it had HID calculate the resolution of the twist axis assuming ABS_RZ instead (so that we would get correct angular behavior). This was broken with the introduction of commit 08a46b4190d3 ("HID: wacom: Set a default resolution for older tablets"), which moved the resolution calculation to occur *before* the adjustment from ABS_Z to ABS_RZ occurred. This commit moves the calculation of resolution after the point that we are finished setting things up for its proper use.

2024-08-02HID: amd_sfh: free driver_data after destroying hid deviceOlivier Sobrie
HID driver callbacks aren't called anymore once hid_destroy_device() has been called. Hence, hid driver_data should be freed only after the hid_destroy_device() function returned as driver_data is used in several callbacks.

2024-08-02drm/test: fix the gem shmem test to map the sg table.Dave Airlie
The test here creates an sg table, but never maps it, when we get to drm_gem_shmem_free, the helper tries to unmap and this causes warnings on some platforms and debug kernels.

2024-08-01scsi: sd: Move sd_read_cpr() out of the q->limits_lock regionShin'ichiro Kawasaki
Commit 804e498e0496 ("sd: convert to the atomic queue limits API") introduced pairs of function calls to queue_limits_start_update() and queue_limits_commit_update(). These two functions lock and unlock q->limits_lock. In sd_revalidate_disk(), sd_read_cpr() is called after queue_limits_start_update() call and before queue_limits_commit_update() call. sd_read_cpr() locks q->sysfs_dir_lock and &q->sysfs_lock. Then new lock dependencies were created between q->limits_lock, q->sysfs_dir_lock and q->sysfs_lock, as follows: sd_revalidate_disk queue_limits_start_update mutex_lock(&q->limits_lock) sd_read_cpr disk_set_independent_access_ranges mutex_lock(&q->sysfs_dir_lock) mutex_lock(&q->sysfs_lock) mutex_unlock(&q->sysfs_lock) mutex_unlock(&q->sysfs_dir_lock) queue_limits_commit_update mutex_unlock(&q->limits_lock) However, the three locks already had reversed dependencies in other places. Then the new dependencies triggered the lockdep WARN "possible circular locking dependency detected" [1]. This WARN was observed by running the blktests test case srp/002. To avoid the WARN, move the sd_read_cpr() call in sd_revalidate_disk() after the queue_limits_commit_update() call. In other words, move the sd_read_cpr() call out of the q->limits_lock region.

2024-08-01scsi: ufs: core: Fix hba->last_dme_cmd_tstamp timestamp updating logicVamshi Gajjela
The ufshcd_add_delay_before_dme_cmd() always introduces a delay of MIN_DELAY_BEFORE_DME_CMDS_US between DME commands even when it's not required. The delay is added when the UFS host controller supplies the quirk UFSHCD_QUIRK_DELAY_BEFORE_DME_CMDS. Fix the logic to update hba->last_dme_cmd_tstamp to ensure subsequent DME commands have the correct delay in the range of 0 to MIN_DELAY_BEFORE_DME_CMDS_US. Update the timestamp at the end of the function to ensure it captures the latest time after any necessary delay has been applied.

2024-08-01PCI: pciehp: Retain Power Indicator bits for userspace indicatorsBlazej Kucman
The sysfs "attention" file normally controls the Slot Control Attention Indicator with 0 (off), 1 (on), 2 (blink) settings. 576243b3f9ea ("PCI: pciehp: Allow exclusive userspace control of indicators") added pciehp_set_raw_indicator_status() to allow userspace to directly control all four bits in both the Attention Indicator and the Power Indicator fields via the "attention" file. This is used on Intel VMD bridges so utilities like "ledmon" can use sysfs "attention" to control up to 16 indicators for NVMe device RAID status. abaaac4845a0 ("PCI: hotplug: Use FIELD_GET/PREP()") broke this by masking the sysfs data with PCI_EXP_SLTCTL_AIC, which discards the upper two bits intended for the Power Indicator Control field (PCI_EXP_SLTCTL_PIC). For NVMe devices behind an Intel VMD, ledmon settings that use the PCI_EXP_SLTCTL_PIC bits, i.e., ATTENTION_REBUILD (0x5), ATTENTION_LOCATE (0x7), ATTENTION_FAILURE (0xD), ATTENTION_OFF (0xF), no longer worked correctly. Mask with PCI_EXP_SLTCTL_AIC | PCI_EXP_SLTCTL_PIC to retain both the Attention Indicator and the Power Indicator bits.

2024-08-01PCI: Fix devres regression in pci_intx()Philipp Stanner
pci_intx() becomes managed if pcim_enable_device() has been called in advance. Commit 25216afc9db5 ("PCI: Add managed pcim_intx()") changed this behavior so that pci_intx() always leads to creation of a separate device resource for itself, whereas earlier, a shared resource was used for all PCI devres operations. Unfortunately, pci_intx() seems to be used in some drivers' remove() paths; in the managed case this causes a device resource to be created on driver detach, which causes .probe() to fail if the driver is reloaded: pci 0000:00:1f.2: Resources present before probing Fix the regression by only redirecting pci_intx() to its managed twin pcim_intx() if the pci_command changes.

2024-08-01perf: riscv: Fix selecting counters in legacy modeShifrin Dmitry
It is required to check event type before checking event config. Events with the different types can have the same config. This check is missed for legacy mode code For such perf usage: sysctl -w kernel.perf_user_access=2 perf stat -e cycles,L1-dcache-loads -- driver will try to force both events to CYCLE counter. This commit implements event type check before forcing events on the special counters.
