2021-01-25iwlwifi: pcie: add rules to match Qu with Hr2Luca Coelho
Until now we have been relying on matching the PCI ID and subsystem device ID in order to recognize Qu devices with Hr2. Add rules to match these devices, so that we don't have to add a new rule for every new ID we get.

2021-01-25iwlwifi: mvm: invalidate IDs of internal stations at mvm startGregory Greenman
Having sta_id not set for aux_sta and snif_sta can potentially lead to a hard to debug issue in case remove station is called without an add. In this case sta_id 0, an unrelated regular station, will be removed. In fact, we do have a FW assert that occures rarely and from the debug data analysis it looks like sta_id 0 is removed by mistake, though it's hard to pinpoint the exact flow. The WARN_ON in this patch should help to find it.

2021-01-25iwlwifi: mvm: fix the return type for DSM functions 1 and 2Matt Chen
The return type value of functions 1 and 2 were considered to be an integer inside a buffer, but they can also be only an integer, without the buffer. Fix the code in iwl_acpi_get_dsm_u8() to handle it as a single integer value, as well as packed inside a buffer.

2021-01-25iwlwifi: pcie: reschedule in long-running memory readsJohannes Berg
If we spin for a long time in memory reads that (for some reason in hardware) take a long time, then we'll eventually get messages such as watchdog: BUG: soft lockup - CPU#2 stuck for 24s! [kworker/2:2:272] This is because the reading really does take a very long time, and we don't schedule, so we're hogging the CPU with this task, at least if CONFIG_PREEMPT is not set, e.g. with CONFIG_PREEMPT_VOLUNTARY=y. Previously I misinterpreted the situation and thought that this was only going to happen if we had interrupts disabled, and then fixed this (which is good anyway, however), but that didn't always help; looking at it again now I realized that the spin unlock will only reschedule if CONFIG_PREEMPT is used. In order to avoid this issue, change the code to cond_resched() if we've been spinning for too long here.

2021-01-25iwlwifi: pcie: use jiffies for memory read spin time limitJohannes Berg
There's no reason to use ktime_get() since we don't need any better precision than jiffies, and since we no longer disable interrupts around this code (when grabbing NIC access), jiffies will work fine. Use jiffies instead of ktime_get(). This cleanup is preparation for the following patch "iwlwifi: pcie: reschedule in long-running memory reads". The code gets simpler with the weird clock use etc. removed before we add cond_resched().

To avoid completion timeouts during device boot, set up the LTR timeouts on more devices - similar to what we had before for AX210.

2021-01-25iwlwifi: fix the NMI flow for old devicesEmmanuel Grumbach
I noticed that the flow that triggers an NMI on the firmware for old devices (tested on 7265) doesn't work. Apparently, the firmware / device is still in low power when we write the register that triggers the NMI. We call the "grab_nic_access" function to make sure the device is awake but that wasn't enough. I played with this and noticed that if we wait 1 ms after the device reports it is awake before we write to the NMI register, the device always sees our write and the firmware gets properly asserted. Triggering an NMI to the firmware can be done with the debugfs hook: echo 1 > /sys/kernel/debug/iwlwifi/0000\:00\:03.0/iwlmvm/fw_nmi What happened before is that the firmware would just stall without running its NMI routine. Because of that the driver wouldn't get the "firmware crashed" interrupt. After a while the driver would notice that the firmware is not responding to some command and it would read the error data from the firmware, but this data is populated in the NMI service routine in the firmware which was not called. So in the logs it looked like: iwlwifi 0000:00:03.0: Error sending REPLY_ERROR: time out after 2000ms. iwlwifi 0000:00:03.0: Current CMD queue read_ptr 33 write_ptr 34 iwlwifi 0000:00:03.0: Loaded firmware version: 29.09bd31e1.0 7265D-29.ucode iwlwifi 0000:00:03.0: 0x00000000 | ADVANCED_SYSASSERT iwlwifi 0000:00:03.0: 0x00000000 | trm_hw_status0 iwlwifi 0000:00:03.0: 0x00000000 | trm_hw_status1 iwlwifi 0000:00:03.0: 0x00000000 | branchlink2 iwlwifi 0000:00:03.0: 0x00000000 | interruptlink1 iwlwifi 0000:00:03.0: 0x00000000 | interruptlink2 iwlwifi 0000:00:03.0: 0x00000000 | data1 iwlwifi 0000:00:03.0: 0x00000000 | data2 iwlwifi 0000:00:03.0: 0x00000000 | data3 iwlwifi 0000:00:03.0: 0x00000000 | beacon time iwlwifi 0000:00:03.0: 0x00000000 | tsf low ...

2021-01-25drm/vc4: Correct lbm size and calculationDom Cobley
LBM base address is measured in units of pixels per cycle. That is 4 for 2711 (hvs5) and 2 for 2708. We are wasting 75% of lbm by indexing without the scaling. But we were also using too high a size for the lbm resulting in partial corruption (right hand side) of vertically scaled images, usually at 4K or lower resolutions with more layers. The physical RAM of LBM on 2711 is 8 * 1920 * 16 * 12-bit (pixels are stored 12-bits per component regardless of format). The LBM address indexes work in units of pixels per clock, so for 4 pixels per clock that means we have 32 * 1920 = 60K Fixes: c54619b0bfb3 ("drm/vc4: Add support for the BCM2711 HVS5") Signed-off-by: Dom Cobley <popcornmix@gmail.com> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Reviewed-by: Dave Stevenson <dave.stevenson@raspberrypi.com> Tested-By: Lucas Nussbaum <lucas@debian.org> Tested-By: Ryutaroh Matsumoto <ryutaroh@ict.e.titech.ac.jp> Link: https://patchwork.freedesktop.org/patch/msgid/20210121105759.1262699-1-maxime@cerno.tech

Palm ejection stops working on some Elan and Synaptics touchpad after commit 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk for some devices"). The commit changes the mt_class from MT_CLS_WIN_8 to MT_CLS_WIN_8_FORCE_MULTI_INPUT, so MT_QUIRK_CONFIDENCE isn't applied anymore. So also apply the quirk since MT_CLS_WIN_8_FORCE_MULTI_INPUT is essentially MT_CLS_WIN_8.

2021-01-24Input: iqs5xx - allow device to be a wake-up sourceJeff LaBundy
Avoid placing the device in suspend mode (from which it cannot generate interrupts) if it is defined as a wake-up source. The device is still permitted to enter a low-power sensing mode on its own.

2021-01-24Input: iqs5xx - allow more time for ATI to completeJeff LaBundy
After the device is initialized, it runs ATI (calibration) during which it cannot readily respond to I2C communication. To keep the open and close callbacks from writing to the device too soon, the driver waits 100 ms before returning from probe. The vendor reports that ATI may actually take up to 250 ms to run (including margin), so increase the delay accordingly. Update the comments to clarify the reason for the delay as well.

2021-01-24Input: iqs5xx - eliminate unnecessary register readJeff LaBundy
Instead of relying on firmware to enable important register fields and performing read-modify-write operations to additionally enable the fields the driver cares about, it's much simpler just to write all of the pertinent fields explicitly. This avoids an unnecessary register read operation at start-up and makes way for the iqs5xx_read_byte() helper to be dropped.

2021-01-24Input: iqs5xx - simplify axis setup logicJeff LaBundy
The present implementation manipulates axis swap and inversion fields in the device to more or less duplicate what touchscreen_report_pos() does. The resulting logic is convoluted and difficult to follow. Instead report the maximum X and Y coordinates in earnest as they are read from the device, then let touchscreen_parse_properties() fix the axes up as necessary. Finally, use touchscreen_report_pos() to report the transformed coordinates. Last but not least, the maximum X and Y coordinates are not functions of the number of rows/columns that comprise the touch surface. Either coordinate is simply limited to 1 below what is reported for absolute X or Y coordinates when no fingers are present (0xFFFF).

2021-01-24Input: iqs5xx - re-initialize device upon warm resetJeff LaBundy
The device may be inadvertently reset during runtime in the event of ESD strike, etc. To protect against this case, acknowledge the SHOW_RESET interrupt and re-initialize the device. To facilitate this change, expand the range of registers that are read in the interrupt handler to include the system status fields. Also, update the unrelated (but nearby) SUSPEND register field to use the BIT() macro. The remaining register fields are cleaned up in another patch.

2021-01-24Input: iqs5xx - accommodate bootloader latencyJeff LaBundy
The bootloader NAK's all I2C communication after the first 64-byte bulk write if the bus frequency is equal to 400 kHz. This prevents the platform from pushing updated firmware to the device. The vendor's USB bootloader programming dongle appears to insert a delay between the "open" command and the first 64-byte bulk write. Adding a similar delay to the driver seems to eliminate the issue. Furthermore, the dongle does not access the bootloader immediately after powering up the device. Follow suit by adding a delay before the "open" command to avoid wasted retries at 400 kHz.

2021-01-24Input: iqs5xx - preserve bootloader errorsJeff LaBundy
After user space writes the fw_file attribute to push new firmware to the device, the driver calls iqs5xx_dev_init() to re-initialize the device with the updated firmware or recover the device in case the update failed. In the case of the latter, however, iqs5xx_fw_file_write() returns zero (success) so long as iqs5xx_dev_init() does not fail, and any error encountered during the update process is lost. Solve this by saving the error before calling iqs5xx_dev_init().

2021-01-24Input: iqs5xx - minor cosmetic improvementsJeff LaBundy
Copyrights are generally followed by the name of a person or a company (i.e. the copyright holder) but that was not done here. Fix this by squashing the 'copyright' and 'author' lines. Also, trim some leading whitespace ahead of the parameters for the fw_file_store() function and re-align them for readability.

2021-01-22net: octeontx2: Make sure the buffer is 128 byte alignedKevin Hao
The octeontx2 hardware needs the buffer to be 128 byte aligned. But in the current implementation of napi_alloc_frag(), it can't guarantee the return address is 128 byte aligned even the request size is a multiple of 128 bytes, so we have to request an extra 128 bytes and use the PTR_ALIGN() to make sure that the buffer is aligned correctly.
