git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2021-10-26 HW-GRO support in mlx5 Beside the HW GRO this series includes two trivial non-mlx5 patches: - net: Prevent HW-GRO and LRO features operate together - lib: bitmap: Introduce node-aware alloc API Khalid Manaa Says: ================== This series implements the HW-GRO offload using the HW feature SHAMPO. HW-GRO: Hardware offload for the Generic Receive Offload feature. SHAMPO: Split Headers And Merge Payload Offload. This feature performs headers data split for each received packed and merge the payloads of the packets of the same session. There are new HW components for this feature: The headers buffer: – cyclic buffer where the packets headers will be located Reservation buffer: – capability to divide RQ WQEs to reservations, a definite size in granularity of 4KB, the reservation is used to define the largest segment that we can create by packets stitching. Each reservation will have a session and the new received packet can be merged to the session, terminate it, or open a new one according to the match criteria. When a new packet is received the headers will be written to the headers buffer and the data will be written to the reservation, in case the packet matches the session the data will be written continuously otherwise it will be written after performing an alignment. SHAMPO RQ, WQ and CQE changes: ----------------------------- RQ (receive queue) new params: -shampo_no_match_alignment_granularity: the HW alignment granularity in case the received packet doesn't match the current session. -shampo_match_criteria_type: the type of match criteria. -reservation_timeout: the maximum time that the HW will hold the reservation. -Each RQ has SKB that represents the current opened flow. WQ (work queue) new params: -headers_mkey: mkey that represents the headers buffer, where the packets headers will be written by the HW. -shampo_enable: flag to verify if the WQ supports SHAMPO feature. -log_reservation_size: the log of the reservation size where the data of the packet will be written by the HW. -log_max_num_of_packets_per_reservation: log of the maximum number of packets that can be written to the same reservation. -log_headers_entry_size: log of the header entry size of the headers buffer. -log_headers_buffer_entry_num: log of the entries number of the headers buffer. CQEs (Completion queue entry) SHAMPO fields: -match: in case it is set, then the current packet matches the opened session. -flush: in case it is set, the opened session must be flushed. -header_size: the size of the packet’s headers. -header_entry_index: the entry index in the headers buffer of the received packet headers. -data_offset: the offset of the received packet data in the WQE. HW-GRO works as follow: ---------------------- The feature can be enabled on the interface using the ethtool command by setting on rx-gro-hw. When the feature is on the mlx5 driver will reopen the RQ to support the SHAMPO feature: Will allocate the headers buffer and fill the parameters regarding the reservation and the match criteria. Receive packet flow: each RQ will hold SKB that represents the current GRO opened session. The driver has a new CQE handler mlx5e_handle_rx_cqe_mpwrq_shampo which will use the CQE SHAMPO params to extract the location of the packet’s headers in the headers buffer and the location of the packets data in the RQ. Also, the CQE has two flags flush and match that indicate if the current packet matches the current session or not and if we need to close the session. In case there is an opened session, and we receive a matched packet then the handler will merge the packet's payload to the current SKB, in case we receive no match then the handler will flush the SKB and create a new one for the new packet. In case the flash flag is set then the driver will close the session, the SKB will be passed to the network stack. In case the driver merges packets in the SKB, before passing the SKB to the network stack the driver will update the checksum of the packet’s headers. SKB build: --------- The driver will build a new SKB in the following situations: in case there is no current opened session. In case the current packet doesn’t match the current session. In case there is no place to add the packets data to the SKB that represents the current session. Otherwise, the driver will add the packet’s data to the SKB. When the driver builds a new SKB, the linear area will contain only the packet headers and the data will be added to the SKB fragments. In case the entry size of the headers buffer is sufficient to build the SKB it will be used, otherwise the driver will allocate new memory to build the SKB. ================== ==================== Signed-off-by: David S.

2021-10-27block: Fix partition check for host-aware zoned block devicesShin'ichiro Kawasaki
Commit a33df75c6328 ("block: use an xarray for disk->part_tbl") modified the method to check partition existence in host-aware zoned block devices from disk_has_partitions() helper function call to empty check of xarray disk->part_tbl. However, disk->part_tbl always has single entry for disk->part0 and never becomes empty. This resulted in the host-aware zoned devices always judged to have partitions, and it made the sysfs queue/zoned attribute to be "none" instead of "host-aware" regardless of partition existence in the devices. This also caused DEBUG_LOCKS_WARN_ON(lock->magic != lock) for sdkp->rev_mutex in scsi layer when the kernel detects host-aware zoned device. Since block layer handled the host-aware zoned devices as non- zoned devices, scsi layer did not have chance to initialize the mutex for zone revalidation. Therefore, the warning was triggered. To fix the issues, call the helper function disk_has_partitions() in place of disk->part_tbl empty check. Since the function was removed with the commit a33df75c6328, reimplement it to walk through entries in the xarray disk->part_tbl.

2021-10-27arm64: dts: apple: j274: Expose PCI node for the Ethernet MAC addressMarc Zyngier
At the moment, all the Minis running Linux have the same MAC address (00:10:18:00:00:00), which is a bit annoying. Expose the PCI node corresponding to the Ethernet device, and declare a 'local-mac-address' property. The bootloader will update it (m1n1 already has the required feature). And if it doesn't, then the default value is already present in the DT. This relies on forcing the bus number for each port so that the endpoints connected to them are correctly numbered (and keeps dtc quiet).

2021-10-27powerpc/64s/interrupt: Fix check_return_regs_valid() false positiveNicholas Piggin
The check_return_regs_valid() can cause a false positive if the return regs are marked as norestart and they are an HSRR type interrupt, because the low bit in the bottom of regs->trap causes interrupt type matching to fail. This can occcur for example on bare metal with a HV privileged doorbell interrupt that causes a signal, but do_signal returns early because get_signal() fails, and takes the "No signal to deliver" path. In this case no signal was delivered so the return location is not changed so return SRRs are not invalidated, yet set_trap_norestart is called, which messes up the match. Building go-1.16.6 is known to reproduce this. Fix it by using the TRAP() accessor which masks out the low bit.

2021-10-27drm/i915: Reduce bigjoiner special casingVille Syrjälä
Try to make bigjoiner pipes less special. The main things here are that each pipe now does full clock computation/readout with its own shared_dpll reference. Also every pipe's cpu_transcoder always points correctly at the master transcoder. Due to the above changes state readout is now complete and all the related hacks can go away. The actual modeset sequence code is still a mess, but I think in order to clean that up properly we're probably going to have to redesign the modeset logic to treat transcoders vs. pipes separately. That is going to require significant amounts of work.

2021-10-27drm/i915: Disable all planes before modesetting any pipesVille Syrjälä
Let's disable planes on all pipes affected by the modeset before we start doing the actual modeset. This means we have less random planes enabled during the modeset, and it also mirrors what we already do when enabling pipes on skl+ since we enable planes on all pipes as the very last step. As a bonus we also nuke a bunch og bigjoiner special casing. I've occasionally pondered about going even furher here and doing the pre_plane_update() stuff for all pipes first, then actually disabling the planes, and finally running the rest of the modeset sequence. This would potentially allow parallelizing all the extra vblank waits across multiple pipes, and would make the plane disable even more atomic. But let's go one step a time here.

2021-10-27Revert "drm/i915/display: Disable audio, DRRS and PSR before planes"Ville Syrjälä
Disabling planes in the middle of the modeset seuqnece does not make sense since userspace can anyway disable planes before the modeset even starts. So when the modeset seuqence starts the set of enabled planes is entirely arbitrary. Trying to sprinkle the plane disabling into the modeset sequence just means more randomness and potential for hard to reproduce bugs. So it makes most sense to just disable all planes first so that the rest of the modeset sequence remains identical regardless of which planes happen to be enabled by userspace at the time.

2021-10-27drm/i915/psr: Disable PSR before modesets turn off all planesVille Syrjälä
PSR2 apparently requires some planes to be enabled for some silly reason, and so we are now trying to turn PSR off before planes go off. Except during a full modeset that is handled less clearly through reorganization of the modeset sequence. That is not great as it makes the code mode complex, and prevents us from doing nice things such as just turning off all the planes at the very start of the modeset. So let's move the PSR pre_plane_update() thing to a spot where it will handle both full modesets and everything else.

Plumb the pieces to add a FID report to error records. Since all error event memory must be pre-allocated, we pre-allocate the maximum file handle size possible, such that it should always fit. For errors that don't expose a file handle, report it with an invalid FID. Internally we use zero-length FILEID_ROOT file handle for passing the information (which we report as zero-length FILEID_INVALID file handle to userspace) so we update the handle reporting code to deal with this case correctly.
