[PATCH] Revert "wifi: ath12k: Enable REO queue lookup table feature on QCN9274 hw2.0"

by Oliver Sedlbauer

This reverts commit 3b5e5185881edf4ee5a1af575e3aedac4a38a764. The REO queue lookup table feature was enabled in 6.12.y due to an upstream backport, but it causes severe RX performance degradation on QCN9274 hw2.0 devices. With this feature enabled, the vast majority of received packets are dropped, reducing throughput drastically and making the device nearly unusable. Reverting this change restores full RX performance. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.5-01651-QCAHKSWPL_SILICONZ-1 Fixes: 3b5e5185881e ("wifi: ath12k: Enable REO queue lookup table feature on QCN9274 hw2.0") Signed-off-by: Oliver Sedlbauer <os(a)dev.tdt.de> --- Note: This commit reverts a backport that was not a fix. The backported change breaks previously working behavior on QCN9274 hw2.0 devices and should not have been applied to the 6.12.y stable kernel. drivers/net/wireless/ath/ath12k/hw.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/wireless/ath/ath12k/hw.c b/drivers/net/wireless/ath/ath12k/hw.c index 057ef2d282b2..e3eb22bb9e1c 100644 --- a/drivers/net/wireless/ath/ath12k/hw.c +++ b/drivers/net/wireless/ath/ath12k/hw.c @@ -1084,7 +1084,7 @@ static const struct ath12k_hw_params ath12k_hw_params[] = { .download_calib = true, .supports_suspend = false, .tcl_ring_retry = true, - .reoq_lut_support = true, + .reoq_lut_support = false, .supports_shadow_regs = false, .num_tcl_banks = 48, -- 2.39.5

[PATCH] drm/bridge: ti-sn65dsi83: ignore PLL_UNLOCK errors

by Luca Ceresoli

On hardware based on Toradex Verdin AM62 the recovery mechanism added by commit ad5c6ecef27e ("drm: bridge: ti-sn65dsi83: Add error recovery mechanism") has been reported [0] to make the display turn on and off and and the kernel logging "Unexpected link status 0x01". According to the report, the error recovery mechanism is triggered by the PLL_UNLOCK error going active. Analysis suggested the board is unable to provide the correct DSI clock neede by the SN65DSI84, to which the TI SN65DSI84 reacts by raising the PLL_UNLOCK, while the display still works apparently without issues. On other hardware, where all the clocks are within the components specifications, the PLL_UNLOCK bit does not trigger while the display is in normal use. It can trigger for e.g. electromagnetic interference, which is a transient event and exactly the reason why the error recovery mechanism has been implemented. Idelly the PLL_UNLOCK bit could be ignored when working out of specification, but this requires to detect in software whether it triggers because the device is working out of specification but visually correctly for the user or for good reasons (e.g. EMI, or even because working out of specifications but compromising the visual output). The ongoing analysis as of this writing [1][2] has not yet found a way for the driver to discriminate among the two cases. So as a temporary measure mask the PLL_UNLOCK error bit unconditionally.

[PATCH] ASoC: cs35l41: Always return 0 when a subsystem ID is found

by Eric Naim

When trying to get the system name in the _HID path, after successfully retrieving the subsystem ID the return value isn't set to 0 but instead still kept at -ENODATA, leading to a false negative: [ 12.382507] cs35l41 spi-VLV1776:00: Subsystem ID: VLV1776 [ 12.382521] cs35l41 spi-VLV1776:00: probe with driver cs35l41 failed with error -61 Always return 0 when a subsystem ID is found to mitigate these false negatives.

[PATCH v2] wifi: ath5k: do not access array OOB

by Jiri Slaby (SUSE)

Vincent reports: > The ath5k driver seems to do an array-index-out-of-bounds access as > shown by the UBSAN kernel message: > UBSAN: array-index-out-of-bounds in drivers/net/wireless/ath/ath5k/base.c:1741:20 > index 4 is out of range for type 'ieee80211_tx_rate [4]' > ... > Call Trace: > <TASK> > dump_stack_lvl+0x5d/0x80 > ubsan_epilogue+0x5/0x2b > __ubsan_handle_out_of_bounds.cold+0x46/0x4b > ath5k_tasklet_tx+0x4e0/0x560 [ath5k] > tasklet_action_common+0xb5/0x1c0 It is real. 'ts->ts_final_idx' can be 3 on 5212, so: info->status.rates[ts->ts_final_idx + 1].idx = -1; with the array defined as: struct ieee80211_tx_rate rates[IEEE80211_TX_MAX_RATES]; while the size is: #define IEEE80211_TX_MAX_RATES 4 is indeed bogus. Set this 'idx = -1' sentinel only if the array index is less than the array size. As mac80211 will not look at rates beyond the size (IEEE80211_TX_MAX_RATES). Note: The effect of the OOB write is negligible. It just overwrites the next member of info->status, i.e. ack_signal.

[tip: perf/urgent] perf/x86/amd/uncore: Fix the return value of amd_uncore_df_event_init() on error
