| | * | | | | drm/msm/dpu: Remove duplicate register defines from INTFMarijn Suijten2023-04-261-5/+0

| | * | | | | drm/msm/dpu: Set PINGPONG block length to zero for DPU >= 7.0.0Marijn Suijten2023-04-264-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Despite downstream DTS stating otherwise, the PINGPONG block has no registers starting with DPU revision 7.0.0. TEAR registers are gone since DPU 5.0.0 after being moved to the INTF block, and DSC registers are gone since 7.0.0, leaving only the dither sub-block. A future patch, part of the DSC 1.2 series, should disable DSC functions on the PINGPONG block for all DPU >= 7.0.0 hardware.

Especially since neither downstream nor upstream utilize these registers in any way, remove the erroneous specification from SM8150, SC8180X, SM8250, SC7180, SM8350, SC8280XP and SM8450 to prevent confusion. Note that downstream enables the PPSPLIT (split-FIFO) topology (single LM for 2 PP and 2 INTF) based on the presence of a TE2 block.

The timeout of this request would not fire, no one would increase iodone_cnt. The above flow would result the iodone_cnt smaller than iorequest_cnt.

If the size of the I/O request requires more PFNs, a separate memory area of exactly the correct size is dynamically allocated. But when the pre-allocated area is used, current code always passes MAX_PAGE_BUFFER_COUNT PFNs to Hyper-V, even if fewer are needed. While this doesn't break anything because the additional PFNs are always zero, more bytes than necessary are copied into the VMBus channel ring buffer. This takes CPU cycles and wastes space in the ring buffer. For a typical 4 Kbyte I/O that requires only a single PFN, 248 unnecessary bytes are copied. Fix this by setting the payload_sz based on the actual number of PFNs required, not the size of the pre-allocated space.

This prevents that general purpose register zero is used for the state parameter. If the compiler would select general purpose register zero this would be problematic for the used instruction in rsy format: the register used for the state parameter is a base register. If the base register is general purpose register zero the contents of the register are unexpectedly ignored when the instruction is executed. This only applies to z/VM guests using QIOASSIST with dedicated (pass through) QDIO-based devices such as FCP [zfcp driver] as well as real OSA or HiperSockets [qeth driver]. A possible symptom for this case using zfcp is the following repeating kernel message pattern: zfcp <devbusid>: A QDIO problem occurred zfcp <devbusid>: A QDIO problem occurred zfcp <devbusid>: qdio: ZFCP on SC <sc> using AI:1 QEBSM:1 PRI:1 TDD:1 SIGA: W zfcp <devbusid>: A QDIO problem occurred zfcp <devbusid>: A QDIO problem occurred Each of the qdio problem message can be accompanied by the following entries for the affected subchannel <sc> in /sys/kernel/debug/s390dbf/qdio_error/hex_ascii for zfcp or qeth: <sc> ccq: 69.... <sc> SQBS ERROR.

This is because, in the past, if the device in the subchannel is not working or not available, we used to unregister the subchannels. But, from the 'commit 2297791c92d0 ("s390/cio: dont unregister subchannel from child-drivers")' we allow subchannels with or without an active device connected on it. So, when we do the io_subchannel_verify, make sure that, we are evaluating the subchannels without any device too.

This can cause the driver Tx flush completion to get out of sync. To avoid this problem, don't enable the "Transmit buffer flush done" (TFD) interrupt and remove the code handling it.

The brcmfmac resume fix has been reported by several people so I would say it's the most important here. The iwlwifi RFI workaround is also something which was reported as a regression recently. * tag 'wireless-2023-05-17' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless: (31 commits) wifi: b43: fix incorrect __packed annotation wifi: rtw88: sdio: Always use two consecutive bytes for word operations mac80211_hwsim: fix memory leak in hwsim_new_radio_nl wifi: iwlwifi: mvm: Add locking to the rate read flow wifi: iwlwifi: Don't use valid_links to iterate sta links wifi: iwlwifi: mvm: don't trust firmware n_channels wifi: iwlwifi: mvm: fix OEM's name in the tas approved list wifi: iwlwifi: fix OEM's name in the ppag approved list wifi: iwlwifi: mvm: fix initialization of a return value wifi: iwlwifi: mvm: fix access to fw_id_to_mac_id wifi: iwlwifi: fw: fix DBGI dump wifi: iwlwifi: mvm: fix number of concurrent link checks wifi: iwlwifi: mvm: fix cancel_delayed_work_sync() deadlock wifi: iwlwifi: mvm: don't double-init spinlock wifi: iwlwifi: mvm: always free dup_data wifi: mac80211: recalc chanctx mindef before assigning wifi: mac80211: consider reserved chanctx for mindef wifi: mac80211: simplify chanctx allocation wifi: mac80211: Abort running color change when stopping the AP wifi: mac80211: fix min center freq offset tracing ... ==================== Link: https://lore.kernel.org/r/20230517151914.B0AF6C433EF@smtp.kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

As the struct itself is also marked as __packed, there is no need to mark its members, so just move the annotation to the inner type instead. As Michael noted, the same problem is present in b43legacy, so change both at the same time.

So and sdio_{read,write}w fails with messages like the following example using an RTL8822BS (but the same problems were also observed with RTL8822CS and RTL8723DS chips): rtw_8822bs mmc1:0001:1: Firmware version 27.2.0, H2C version 13 sunxi-mmc 4021000.mmc: unaligned scatterlist: os f80 length 2 sunxi-mmc 4021000.mmc: map DMA failed rtw_8822bs mmc1:0001:1: sdio read16 failed (0x10230): -22 Use two consecutive single byte accesses for word operations instead. It turns out that upon closer inspection this is also what the vendor driver does, even though it does have support for sdio_{read,write}w. So we can conclude that the rtw88 chips do support word access but only on SDIO controllers that also support it. Since there's no way to detect if the controller supports word access or not the rtw88 sdio driver switches to the easiest approach: avoiding word access.

This read flow is not protected thereby leaving a small window, a few instructions wide, open to contention by an asynchronous rate update. Indeed this race condition was hit and the update occurred in the middle of the read. Fix this by locking the lq_sta struct during read.
