2023-06-21wifi: rtw89: 8851b: configure to force 1 TX power valuePing-Ke Shih
RTL8851B is a chip with only single RF path, and it must use 1 TX power value for transmission, so force 1 TX power value to prevent hardware logic gets wrong TX power values randomly in certain samples.

2023-06-21wifi: rtw89: 8851b: rfk: update IQK to version 0x8Ping-Ke Shih
The main change is to adjust RX calibration groups from {0,1,2,3} to {0,2} in 5 GHz, so reduce elements from 4 to 2, and use index to iterate them. Meanwhile, always do RX narrowband calibration (ID_NBRXK) for each group. NCTL is used to assist IQK, so also update NCTL to 0x6 along with internal tag HALRF_029_00_103.

2023-06-21wifi: rtw88: fix not entering PS mode after AP stopsPo-Hao Huang
Without this patch, firmware only track beacons for port 0 and since we will always start AP on port 0, this results in misbehavior of power saving mode on other ports after AP stops. The "default port" H2C command is used to notify which port should firmware track. Update the correct settings to firmware so power saving mode can work properly.

Broadcast and multicast packets in high queue should be transmitted all at once during DTIM. But without proper settings, hardware fails to recognize that there are multiple packets and fetches only one. Fix this by signaling hardware with more data bit set when there are packets in the high queue.

2023-06-21wifi: rtw88: process VO packets without workqueue to avoid PTK rekey failedChih-Kang Chang
In the wpa_supplicant rekey flow, it sends an EAPOL packet 4/4 through nl80211_tx_control_port() and triggers wake_tx_queue() in the driver. Then, it sends nl80211_new_key() to configure a new key in mac80211. However, in wake_tx_queue(), a workqueue is used to process the tx packet, which might cause the driver to process the EAPOL packet later than nl80211_new_key(). As a result, the EAPOL 4/4 packet is dropped by mac80211 due to the rekey configuration being finished. The EAPOL packets belongs to VO packets that need high priority. Therefore, we process VO packets directly without workqueue to ensure that packets can process immediately. VO is normally used by voice application that is low traffic load and low latency, that doesn't affect user experience.

2023-06-21wifi: rtw88: Fix action frame transmission fail before associationPo-Hao Huang
For combo chips, antennas were controlled by bluetooth only during power on. If WiFi wish to do transmission, notification to the coexistence module are required. Previously we only do this before authentication. To allow transmission before auth, such as management TX, now we start the initiation of coexistence earlier so antennas are shared between WiFi and bluetooth after set_channel(), and frames could then be sent.

2023-06-21Revert "virtio-blk: support completion batching for the IRQ path"Michael S. Tsirkin
This reverts commit 07b679f70d73483930e8d3c293942416d9cd5c13. This change appears to have broken things... We now see applications hanging during disk accesses. e.g. multi-port virtio-blk device running in h/w (FPGA) Host running a simple 'fio' test. [global] thread=1 direct=1 ioengine=libaio norandommap=1 group_reporting=1 bs=4K rw=read iodepth=128 runtime=1 numjobs=4 time_based [job0] filename=/dev/vda [job1] filename=/dev/vdb [job2] filename=/dev/vdc ... [job15] filename=/dev/vdp i.e. 16 disks; 4 queues per disk; simple burst of 4KB reads This is repeatedly run in a loop. After a few, normally <10 seconds, fio hangs. With 64 queues (16 disks), failure occurs within a few seconds; with 8 queues (2 disks) it may take ~hour before hanging. Last message: fio-3.19 Starting 8 threads Jobs: 1 (f=1): [_(7),R(1)][68.3%][eta 03h:11m:06s] I think this means at the end of the run 1 queue was left incomplete. 'diskstats' (run while fio is hung) shows no outstanding transactions. e.g. $ cat /proc/diskstats ... 252 0 vda 1843140071 0 14745120568 712568645 0 0 0 0 0 3117947 712568645 0 0 0 0 0 0 252 16 vdb 1816291511 0 14530332088 704905623 0 0 0 0 0 3117711 704905623 0 0 0 0 0 0 ... Other stats (in the h/w, and added to the virtio-blk driver ([a]virtio_queue_rq(), [b]virtblk_handle_req(), [c]virtblk_request_done()) all agree, and show every request had a completion, and that virtblk_request_done() never gets called. e.g. PF= 0 vq=0 1 2 3 [a]request_count - 839416590 813148916 105586179 84988123 [b]completion1_count - 839416590 813148916 105586179 84988123 [c]completion2_count - 0 0 0 0 PF= 1 vq=0 1 2 3 [a]request_count - 823335887 812516140 104582672 75856549 [b]completion1_count - 823335887 812516140 104582672 75856549 [c]completion2_count - 0 0 0 0 i.e. the issue is after the virtio-blk driver. This change was introduced in kernel 6.3.0. I am seeing this using 6.3.3. If I run with an earlier kernel (5.15), it does not occur. If I make a simple patch to the 6.3.3 virtio-blk driver, to skip the blk_mq_add_to_batch()call, it does not fail. e.g. kernel 5.15 - this is OK virtio_blk.c,virtblk_done() [irq handler] if (likely(!blk_should_fake_timeout(req->q))) { blk_mq_complete_request(req); } kernel 6.3.3 - this fails virtio_blk.c,virtblk_handle_req() [irq handler] if (likely(!blk_should_fake_timeout(req->q))) { if (!blk_mq_complete_request_remote(req)) { if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) { virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed } } } If I do, kernel 6.3.3 - this is OK virtio_blk.c,virtblk_handle_req() [irq handler] if (likely(!blk_should_fake_timeout(req->q))) { if (!blk_mq_complete_request_remote(req)) { virtblk_request_done(req); //force this here... if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) { virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed } } } Perhaps you might like to fix/test/revert this change...

2023-06-20regmap: spi-avmm: Fix regmap_bus max_raw_writeRuss Weight
The max_raw_write member of the regmap_spi_avmm_bus structure is defined as: .max_raw_write = SPI_AVMM_VAL_SIZE * MAX_WRITE_CNT SPI_AVMM_VAL_SIZE == 4 and MAX_WRITE_CNT == 1 so this results in a maximum write transfer size of 4 bytes which provides only enough space to transfer the address of the target register. It provides no space for the value to be transferred. This bug became an issue (divide-by-zero in _regmap_raw_write()) after the following was accepted into mainline: commit 3981514180c9 ("regmap: Account for register length when chunking") Change max_raw_write to include space (4 additional bytes) for both the register address and value: .max_raw_write = SPI_AVMM_REG_SIZE + SPI_AVMM_VAL_SIZE * MAX_WRITE_CNT Fixes: 7f9fb67358a2 ("regmap: add Intel SPI Slave to AVMM Bus Bridge support") Reviewed-by: Matthew Gerlach <matthew.gerlach@linux.intel.com> Signed-off-by: Russ Weight <russell.h.weight@intel.com> Link: https://lore.kernel.org/r/20230620202824.380313-1-russell.h.weight@intel.com Signed-off-by: Mark Brown <broonie@kernel.org>

devm_clk_notifier_register() allocates a devres resource for clk notifier but didn't register that to the device, so the notifier didn't get unregistered on device detach and the allocated resource was leaked.

2023-06-20net: phy: mediatek: fix compile-test dependenciesArnd Bergmann
The new phy driver attempts to select a driver from another subsystem, but that fails when the NVMEM subsystem is disabled: WARNING: unmet direct dependencies detected for NVMEM_MTK_EFUSE Depends on [n]: NVMEM [=n] && (ARCH_MEDIATEK [=n] || COMPILE_TEST [=y]) && HAS_IOMEM [=y] Selected by [y]: - MEDIATEK_GE_SOC_PHY [=y] && NETDEVICES [=y] && PHYLIB [=y] && (ARM64 && ARCH_MEDIATEK [=n] || COMPILE_TEST [=y]) I could not see an actual compile time dependency, so presumably this is only needed for for working correctly but not technically a dependency on that particular nvmem driver implementation, so it would likely be safe to remove the select for compile testing. To keep the spirit of the original 'select', just replace this with a 'depends on' that ensures that the driver will work but does not get in the way of build testing.

Rework iterating over DT CPU nodes to iterate over possible CPUs instead. There's no need to walk the DT CPU nodes again. Possible CPUs is equal to the number of CPUs defined in the DT.

It seems that Kingston EMMC04G-M627 despite advertising TRIM support does not work when the core is trying to use REQ_OP_WRITE_ZEROES. We are seeing I/O errors in OpenWrt under 6.1 on Zyxel NBG7815 that we did not previously have and tracked it down to REQ_OP_WRITE_ZEROES. Trying to use fstrim seems to also throw errors like: [93010.835112] I/O error, dev loop0, sector 16902 op 0x3:(DISCARD) flags 0x800 phys_seg 1 prio class 2 Disabling TRIM makes the error go away, so lets add a quirk for this eMMC to disable TRIM.
