2022-12-10PCI: Skip allocate_resource() if too little space availableBjorn Helgaas
pci_bus_alloc_from_region() allocates MMIO space by iterating through all the resources available on the bus. The available resource might be reduced if the caller requires 32-bit space or we're avoiding BIOS or E820 areas. Don't bother calling allocate_resource() if we need more space than is available in this resource. This prevents some pointless and annoying messages about avoided areas.

2022-12-10PCI/portdrv: Allow AER service only for Root Ports & RCECsBjorn Helgaas
Previously portdrv allowed the AER service for any device with an AER capability (assuming Linux had control of AER) even though the AER service driver only attaches to Root Port and RCECs. Because get_port_device_capability() included AER for non-RP, non-RCEC devices, we tried to initialize the AER IRQ even though these devices don't generate AER interrupts. Intel DG1 and DG2 discrete graphics cards contain a switch leading to a GPU. The switch supports AER but not MSI, so initializing an AER IRQ failed, and portdrv failed to claim the switch port at all. The GPU itself could be suspended, but the switch could not be put in a low-power state because it had no driver. Don't allow the AER service on non-Root Port, non-Root Complex Event Collector devices. This means we won't enable Bus Mastering if the device doesn't require MSI, the AER service will not appear in sysfs, and the AER service driver will not bind to the device.

The CAN FD IP found on RZ/G2L SoC has some HW features different to that of R-Car. For example, it has multiple resets and multiple IRQs for global and channel interrupts. Also, it does not have ECC error flag registers and clk post divider present on R-Car. Similarly, R-Car V3U has 8 channels whereas other SoCs has only 2 channels. This patch adds the struct rcar_canfd_hw_info to take care of the HW feature differences and driver data present on both IPs.

When build_skb() is passed a frag_size of 0, it means the buffer came from kmalloc. In these cases, ksize() is used to find its actual size, but since the allocation may not have been made to that size, actually perform the krealloc() call so that all the associated buffer size checking will be correctly notified (and use the "new" pointer so that compiler hinting works correctly).

SW steering is able to match only on the exact values of the packet fields, as requested by the user: the user provides mask for the fields that are of interest, and the exact values to be matched on when the traffic is handled. The following patch series add new type of action - Range Match, where the user provides a field to be matched on and a range of values (min to max) that will be considered as hit. There are several new notions that were implemented in order to support Range Match: - MATCH_RANGES Steering Table Entry (STE): the new STE type that allows matching the packets' fields on the range of values instead of a specific value. - Match Definer: this is a general FW object that defines which fields in the packet will be referenced by the mask and tag of each STE. Match definer ID is part of STE fields, and it defines how the HW needs to interpret the STE's mask/tag values.

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2022-12-08 (ice) Jacob Keller says: This series of patches primarily consists of changes to fix some corner cases that can cause Tx timestamp failures. The issues were discovered and reported by Siddaraju DH and primarily affect E822 hardware, though this series also includes some improvements that affect E810 hardware as well. The primary issue is regarding the way that E822 determines when to generate timestamp interrupts. If the driver reads timestamp indexes which do not have a valid timestamp, the E822 interrupt tracking logic can get stuck. This is due to the way that E822 hardware tracks timestamp index reads internally. I was previously unaware of this behavior as it is significantly different in E810 hardware. Most of the fixes target refactors to ensure that the ice driver does not read timestamp indexes which are not valid on E822 hardware. This is done by using the Tx timestamp ready bitmap register from the PHY. This register indicates what timestamp indexes have outstanding timestamps waiting to be captured. Care must be taken in all cases where we read the timestamp registers, and thus all flows which might have read these registers are refactored. The ice_ptp_tx_tstamp function is modified to consolidate as much of the logic relating to these registers as possible. It now handles discarding stale timestamps which are old or which occurred after a PHC time update. This replaces previously standalone thread functions like the periodic work function and the ice_ptp_flush_tx_tracker function. In addition, some minor cleanups noticed while writing these refactors are included. The remaining patches refactor the E822 implementation to remove the "bypass" mode for timestamps. The E822 hardware has the ability to provide a more precise timestamp by making use of measurements of the precise way that packets flow through the hardware pipeline. These measurements are known as "Vernier" calibration. The "bypass" mode disables many of these measurements in favor of a faster start up time for Tx and Rx timestamping. Instead, once these measurements were captured, the driver tries to reconfigure the PHY to enable the vernier calibrations. Unfortunately this recalibration does not work. Testing indicates that the PHY simply remains in bypass mode without the increased timestamp precision. Remove the attempt at recalibration and always use vernier mode. This has one disadvantage that Tx and Rx timestamps cannot begin until after at least one packet of that type goes through the hardware pipeline. Because of this, further refactor the driver to separate Tx and Rx vernier calibration. Complete the Tx and Rx independently, enabling the appropriate type of timestamp as soon as the relevant packet has traversed the hardware pipeline. This was reported by Milena Olech. Note that although these might be considered "bug fixes", the required changes in order to appropriately resolve these issues is large. Thus it does not feel suitable to send this series to net. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: ice: reschedule ice_ptp_wait_for_offset_valid during reset ice: make Tx and Rx vernier offset calibration independent ice: only check set bits in ice_ptp_flush_tx_tracker ice: handle flushing stale Tx timestamps in ice_ptp_tx_tstamp ice: cleanup allocations in ice_ptp_alloc_tx_tracker ice: protect init and calibrating check in ice_ptp_request_ts ice: synchronize the misc IRQ when tearing down Tx tracker ice: check Tx timestamp memory register for ready timestamps ice: handle discarding old Tx requests in ice_ptp_tx_tstamp ice: always call ice_ptp_link_change and make it void ice: fix misuse of "link err" with "link status" ice: Reset TS memory for all quads ice: Remove the E822 vernier "bypass" logic ice: Use more generic names for ice_ptp_tx fields ==================== Link: https://lore.kernel.org/r/20221208213932.1274143-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-12-09iommufd: Change the order of MSI setupJason Gunthorpe
Eric points out this is wrong for the rare case of someone using allow_unsafe_interrupts on ARM. We always have to setup the MSI window in the domain if the iommu driver asks for it. Move the iommu_get_msi_cookie() setup to the top of the function and always do it, regardless of the security mode. Add checks to iommufd_device_setup_msi() to ensure the driver is not doing something incomprehensible. No current driver will set both a HW and SW MSI window, or have more than one SW MSI window.

2022-12-09crypto: stm32/cryp - enable for use with Ux500Linus Walleij
This adds a few small quirks to handle the differences between the STM32 and Ux500 cryp blocks. The following differences are handled with special bool switch bits in the capabilities: - The main difference is that some registers are removed, so we add register offsets for all registers in the per-variant data. Then we assign the right offsets for Ux500 vs the STM32 variants. - The Ux500 does not support the aeads algorithms; gcm(aes) and ccm(aes). Avoid registering them when running on Ux500. - The Ux500 has a special "linear" key format and does some elaborare bit swizzling of the key bits before writing them into the key registers. This is written as an "application note" inside the DB8500 design specification, and seems to be the result of some mishap when assigning the data lines to register bits. (STM32 has clearly fixed this.) - The Ux500 does not have the KP "key prepare" bit in the CR register. Instead, we need to set the KSE bit, "key schedule encryption" bit which does the same thing but is in bit 11 rather than being a special "algorithm type" as on STM32. The algorithm must however be specified as AES ECB while doing this. - The Ux500 cannot just read out IV registers, we need to set the KEYRDEN "key read enable" bit, as this protects not just the key but also the IV from being read out. Enable this bit before reading out the IV and disable it afterwards.
