2023-09-25wifi: iwlwifi: pcie: (re-)assign BAR0 on driver bindJohannes Berg
There's a race with runtime PM getting enabled by userspace: - we rescan the PCI bus - this creates the new PCI device including its sysfs representation - udev sees the new device, and the (OS-specific?) scripting enables runtime PM by writing to power/control; this can happen _before_ the next step - this will runtime-suspend the device which saves the config space, including the BAR0 that wasn't assigned yet - the bus rescan assigns resources to the devices and writes them to the config space of the device (but not the runtime-pm saved copy) - the driver binds and this disallows runtime PM, so the device is resumed, restoring the (incomplete!) config space - the driver cannot work due to BAR0 not being configured Fixing the actual race is hard and deep in the PCI layer, though probably should be done for upstream as well; perhaps runtime PM should only be allowed after resource assignment, or some other TBD way. Work around this in the driver for now by simply (re-)assigning BAR0 when the driver initializes, if it's unset.

2023-09-25wifi: iwlwifi: implement enable/disable for China 2022 regulatoryAnjaneyulu
China 2022 regulations are enabled by default. Disable only when disabled in BIOS or the firmware don't support this capability. If the firmware has this capability, read BIOS configuration data in function 4 using ACPI API and send GRP_REGULATORY_LARI_CONFIG_CHANGE_CMD to the firmware.

2023-09-25wifi: iwlwifi: mvm: support set_antenna()Emmanuel Grumbach
set_antenna() is supported only when the device is not started in mac80211 which translates to the firmware not being loaded in iwlwifi. The tricky part is that iwlwifi populates the sband data during its boot and doesn't touch this data afterwards, but if the antenna settings forbid MIMO, we need to update the sband data. Rework the nvm parsing code to allow to get an existing nvm_data and modify the sband with additional constraints (tx / rx chains masks).

2023-09-25wifi: cfg80211: report per-link errors during associationBenjamin Berg
When one of the links (other than the assoc_link) is misconfigured and cannot work the association will fail. However, userspace was not able to tell that the operation only failed because of a problem with one of the links. Fix this, by allowing the driver to set a per-link error code and reporting the (first) offending link by setting the bad_attr accordingly. This only allows us to report the first error, but that is sufficient for userspace to e.g. remove the offending link and retry.

2023-09-25wifi: mac80211: support antenna control in injectionJohannes Berg
Support antenna control for injection by parsing the antenna radiotap field (which may be presented multiple times) and telling the driver about the resulting antenna bitmap. Of course there's no guarantee the driver will actually honour this, just like any other injection control. If misconfigured, i.e. the injected HT/VHT MCS needs more chains than antennas are configured, the bitmap is reset to zero, indicating no selection. For now this is only set up for two anntenas so we keep more free bits, but that can be trivially extended if any driver implements support for it that can deal with hardware with more antennas.

2023-09-25ata: libata-sata: increase PMP SRST timeout to 10sMatthias Schiffer
On certain SATA controllers, softreset fails after wakeup from S2RAM with the message "softreset failed (1st FIS failed)", sometimes resulting in drives not being detected again. With the increased timeout, this issue is avoided. Instead, "softreset failed (device not ready)" is now logged 1-2 times; this later failure seems to cause fewer problems however, and the drives are detected reliably once they've spun up and the probe is retried. The issue was observed with the primary SATA controller of the QNAP TS-453B, which is an "Intel Corporation Celeron/Pentium Silver Processor SATA Controller [8086:31e3] (rev 06)" integrated in the Celeron J4125 CPU, and the following drives: - Seagate IronWolf ST12000VN0008 - Seagate IronWolf ST8000NE0004 The SATA controller seems to be more relevant to this issue than the drives, as the same drives are always detected reliably on the secondary SATA controller on the same board (an ASMedia 106x) without any "softreset failed" errors even without the increased timeout.

2023-09-24xfs: fix reloading entire unlinked bucket listsDarrick J. Wong
During review of the patcheset that provided reloading of the incore iunlink list, Dave made a few suggestions, and I updated the copy in my dev tree. Unfortunately, I then got distracted by ... who even knows what ... and forgot to backport those changes from my dev tree to my release candidate branch. I then sent multiple pull requests with stale patches, and that's what was merged into -rc3. So. This patch re-adds the use of an unlocked iunlink list check to determine if we want to allocate the resources to recreate the incore list. Since lost iunlinked inodes are supposed to be rare, this change helps us avoid paying the transaction and AGF locking costs every time we open any inode. This also re-adds the shutdowns on failure, and re-applies the restructuring of the inner loop in xfs_inode_reload_unlinked_bucket, and re-adds a requested comment about the quotachecking code. Retain the original RVB tag from Dave since there's no code change from the last submission.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix the "bytes" output of the per_cpu stat file The tracefs/per_cpu/cpu*/stats "bytes" was giving bogus values as the accounting was not accurate. It is suppose to show how many used bytes are still in the ring buffer, but even when the ring buffer was empty it would still show there were bytes used. - Fix a bug in eventfs where reading a dynamic event directory (open) and then creating a dynamic event that goes into that diretory screws up the accounting. On close, the newly created event dentry will get a "dput" without ever having a "dget" done for it. The fix is to allocate an array on dir open to save what dentries were actually "dget" on, and what ones to "dput" on close. * tag 'trace-v6.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: eventfs: Remember what dentries were created on dir open ring-buffer: Fix bytes info in per_cpu buffer stats

git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl Pull cxl fixes from Dan Williams: "A collection of regression fixes, bug fixes, and some small cleanups to the Compute Express Link code. The regressions arrived in the v6.5 dev cycle and missed the v6.6 merge window due to my personal absences this cycle. The most important fixes are for scenarios where the CXL subsystem fails to parse valid region configurations established by platform firmware. This is important because agreement between OS and BIOS on the CXL configuration is fundamental to implementing "OS native" error handling, i.e. address translation and component failure identification. Other important fixes are a driver load error when the BIOS lets the Linux PCI core handle AER events, but not CXL memory errors. The other fixex might have end user impact, but for now are only known to trigger in our test/emulation environment. Summary: - Fix multiple scenarios where platform firmware defined regions fail to be assembled by the CXL core. - Fix a spurious driver-load failure on platforms that enable OS native AER, but not OS native CXL error handling. - Fix a regression detecting "poison" commands when "security" commands are also defined. - Fix a cxl_test regression with the move to centralize CXL port register enumeration in the CXL core. - Miscellaneous small fixes and cleanups" * tag 'cxl-fixes-6.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/acpi: Annotate struct cxl_cxims_data with __counted_by cxl/port: Fix cxl_test register enumeration regression cxl/region: Refactor granularity select in cxl_port_setup_targets() cxl/region: Match auto-discovered region decoders by HPA range cxl/mbox: Fix CEL logic for poison and security commands cxl/pci: Replace host_bridge->native_aer with pcie_aer_is_native() PCI/AER: Export pcie_aer_is_native() cxl/pci: Fix appropriate checking for _OSC while handling CXL RAS registers

The hdmi@3d node's compatible string is "adi,adv7535" instead of "adi,adv7533" or "adi,adv751*". Fix the hdmi@3d node by means of: * Use default register addresses for "cec", "edid" and "packet", because there is no need to use a non-default address map. * Add missing interrupt related properties. * Drop "adi,input-*" properties which are only valid for adv751*. * Add VDDEXT_3V3 fixed regulator * Add "*-supply" properties, since most are required. * Fix label names - s/adv7533/adv7535/.

2023-09-24soc: imx8m: Enable OCOTP clock for imx8mm before reading registersNathan Rossi
Commit 836fb30949d9 ("soc: imx8m: Enable OCOTP clock before reading the register") added configuration to enable the OCOTP clock before attempting to read from the associated registers. This same kexec issue is present with the imx8m SoCs that use the imx8mm_soc_uid function (e.g. imx8mp). This requires the imx8mm_soc_uid function to configure the OCOTP clock before accessing the associated registers. This change implements the same clock enable functionality that is present in the imx8mq_soc_revision function for the imx8mm_soc_uid function.

Commit 16c984524862 ("arm64: dts: imx8mp: don't initialize audio clocks from CCM node") removed the Audio clocks from the main clock node, because the intent is to force people to setup the audio PLL clocks per board instead of having a common set of rates since not all boards may use the various audio PLL clocks for audio devices. This resulted in an incorrect clock rate when attempting to playback audio, since the AUDIO_PLL2 wasn't set any longer. Fix this by setting the AUDIO_PLL2 rate inside the SAI3 node since it's the SAI3 that needs it.

2023-09-24arm64: dts: imx8mp: Fix SDMA2/3 clocksAdam Ford
Commit 16c984524862 ("arm64: dts: imx8mp: don't initialize audio clocks from CCM node") removed the Audio clocks from the main clock node, because the intent is to force people to setup the audio PLL clocks per board instead of having a common set of rates, since not all boards may use the various audio PLL clocks in the same way. Unfortunately, with this parenting removed, the SDMA2 and SDMA3 clocks were slowed to 24MHz because the SDMA2/3 clocks are controlled via the audio_blk_ctrl which is clocked from IMX8MP_CLK_AUDIO_ROOT, and that clock is enabled by pgc_audio. Per the TRM, "The SDMA2/3 target frequency is 400MHz IPG and 400MHz AHB, always 1:1 mode, to make sure there is enough throughput for all the audio use cases." Instead of cluttering the clock node, place the clock rate and parent information into the pgc_audio node. With the parenting and clock rates restored for IMX8MP_CLK_AUDIO_AHB, and IMX8MP_CLK_AUDIO_AXI_SRC, it appears the SDMA2 and SDMA3 run at 400MHz again.
