[PATCH v2] ASoC: SOF: Intel: broadwell: fix mutual exclusion with catpt driver

by Pierre-Louis Bossart

In v5.10, the "haswell" driver was replaced by the "catpt" driver, but the mutual exclusion with the SOF driver was not updated. This leads to errors with card names and UCM profiles not being loaded by PulseAudio. This fix should only be applied on v5.10-stable, the mutual exclusion was removed in 5.11.

[PATCH FOR stable v5.11] media: cedrus: Remove checking for required controls

by Hans Verkuil

From: Jernej Skrabec <jernej.skrabec(a)siol.net> [ Upstream commit 7072db89572135f28cad65f15877bf7e67cf2ff8 ] According to v4l2 request api specifications, it's allowed to skip control if its content isn't changed for performance reasons. Cedrus driver predates that, so it has implemented mechanism to check if all required controls are included in one request. Conform to specifications with removing that mechanism. Note that this mechanism with static required flag isn't very good anyway because need for control is usually signaled in other controls.

[PATCH net/net-next 2/4] FDDI: defxx: Make MMIO the configuration default except for EISA

by Maciej W. Rozycki

Recent versions of the PCI Express specification have deprecated support for I/O transactions and actually some PCIe host bridges, such as Power Systems Host Bridge 4 (PHB4), do not implement them. The default kernel configuration choice for the defxx driver is the use of I/O ports rather than MMIO for PCI and EISA systems. It may have made sense as a conservative backwards compatible choice back when MMIO operation support was added to the driver as a part of TURBOchannel bus support. However nowadays this configuration choice makes the driver unusable with systems that do not implement I/O transactions for PCIe. Make DEFXX_MMIO the configuration default then, except where configured for EISA. This exception is because an EISA adapter can have its MMIO decoding disabled with ECU (EISA Configuration Utility) and therefore not available with the resource allocation infrastructure we implement, while port I/O is always readily available as it uses slot-specific addressing, directly mapped to the slot an option card has been placed in and handled with our EISA bus support core. Conversely a kernel that supports modern systems which may not have I/O transactions implemented for PCIe will usually not be expected to handle legacy EISA systems. The change of the default will make it easier for people, including but not limited to distribution packagers, to make a working choice for the driver. Update the option description accordingly and while at it replace the potentially ambiguous PIO acronym with IOP for "port I/O" vs "I/O ports" according to our nomenclature used elsewhere.

[PATCH net/net-next 1/4] FDDI: defxx: Bail out gracefully with unassigned PCI resource for CSR

by Maciej W. Rozycki

Recent versions of the PCI Express specification have deprecated support for I/O transactions and actually some PCIe host bridges, such as Power Systems Host Bridge 4 (PHB4), do not implement them. For those systems the PCI BARs that request a mapping in the I/O space have the length recorded in the corresponding PCI resource set to zero, which makes it unassigned: # lspci -s 0031:02:04.0 -v 0031:02:04.0 FDDI network controller: Digital Equipment Corporation PCI-to-PDQ Interface Chip [PFI] FDDI (DEFPA) (rev 02) Subsystem: Digital Equipment Corporation FDDIcontroller/PCI (DEFPA) Flags: bus master, medium devsel, latency 136, IRQ 57, NUMA node 8 Memory at 620c080020000 (32-bit, non-prefetchable) [size=128] I/O ports at <unassigned> [disabled] Memory at 620c080030000 (32-bit, non-prefetchable) [size=64K] Capabilities: [50] Power Management version 2 Kernel driver in use: defxx Kernel modules: defxx # Regardless the driver goes ahead and requests it (here observed with a Raptor Talos II POWER9 system), resulting in an odd /proc/ioport entry: # cat /proc/ioports 00000000-ffffffffffffffff : 0031:02:04.0 # Furthermore, the system gets confused as the driver actually continues and pokes at those locations, causing a flood of messages being output to the system console by the underlying system firmware, like: defxx: v1.11 2014/07/01 Lawrence V. Stefani and others defxx 0031:02:04.0: enabling device (0140 -> 0142) LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010000 IPMI: dropping non severe PEL event LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010014 IPMI: dropping non severe PEL event LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010014 IPMI: dropping non severe PEL event and so on and so on (possibly intermixed actually, as there's no locking between the kernel and the firmware in console port access with this particular system, but cleaned up above for clarity), and once some 10k of such pairs of the latter two messages have been produced an interace eventually shows up in a useless state: 0031:02:04.0: DEFPA at I/O addr = 0x0, IRQ = 57, Hardware addr = 00-00-00-00-00-00 This was not expected to happen as resource handling was added to the driver a while ago, because it was not known at that time that a PCI system would be possible that cannot assign port I/O resources, and oddly enough `request_region' does not fail, which would have caught it. Correct the problem then by checking for the length of zero for the CSR resource and bail out gracefully refusing to register an interface if that turns out to be the case, producing messages like: defxx: v1.11 2014/07/01 Lawrence V. Stefani and others 0031:02:04.0: Cannot use I/O, no address set, aborting 0031:02:04.0: Recompile driver with "CONFIG_DEFXX_MMIO=y" Keep the original check for the EISA MMIO resource as implemented, because in that case the length is hardwired to 0x400 as a consequence of how the compare/mask address decoding works in the ESIC chip and it is only the base address that is set to zero if MMIO has been disabled for the adapter in EISA configuration, which in turn could be a valid bus address in a legacy-free system implementing PCI, especially for port I/O. Where the EISA MMIO resource has been disabled for the adapter in EISA configuration this arrangement keeps producing messages like: eisa 00:05: EISA: slot 5: DEC3002 detected defxx: v1.11 2014/07/01 Lawrence V. Stefani and others 00:05: Cannot use MMIO, no address set, aborting 00:05: Recompile driver with "CONFIG_DEFXX_MMIO=n" 00:05: Or run ECU and set adapter's MMIO location with the last two lines now swapped for easier handling in the driver. There is no need to check for and catch the case of a port I/O resource not having been assigned for EISA as the adapter uses the slot-specific I/O space, which gets assigned by how EISA has been specified and maps directly to the particular slot an option card has been placed in. And the EISA variant of the adapter has additional registers that are only accessible via the port I/O space anyway. While at it factor out the error message calls into helpers and fix an argument order bug with the `pr_err' call now in `dfx_register_res_err'. Signed-off-by: Maciej W.

by CKI Project

Hello, We ran automated tests on a recent commit from this kernel tree: Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git Commit: 2e1a11436ce5 - ACPICA: Fix race in generic_serial_bus (I2C) and GPIO op_region parameter handling The results of these automated tests are provided below. Overall result: PASSED Merge: OK Compile: OK Tests: OK All kernel binaries, config files, and logs are available for download here: https://arr-cki-prod-datawarehouse-public.s3.amazonaws.com/index.html?prefi… Please reply to this email if you have any questions about the tests that we ran or if you have any suggestions on how to make future tests more effective. ,-. ,-.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.
