Pull io_uring updates from Jens Axboe: - Add supported for more directly managed task_work running. This is beneficial for real world applications that end up issuing lots of system calls as part of handling work. Normal task_work will always execute as we transition in and out of the kernel, even for "unrelated" system calls. It's more efficient to defer the handling of io_uring's deferred work until the application wants it to be run, generally in batches. As part of ongoing work to write an io_uring network backend for Thrift, this has been shown to greatly improve performance.

2022-10-07vfio: Make the group FD disassociate from the iommu_groupJason Gunthorpe2-24/+44
Allow the vfio_group struct to exist with a NULL iommu_group pointer. When the pointer is NULL the vfio_group users promise not to touch the iommu_group. This allows a driver to be hot unplugged while userspace is keeping the group FD open. Remove all the code waiting for the group FD to close. This fixes a userspace regression where we learned that virtnodedevd leaves a group FD open even though the /dev/ node for it has been deleted and all the drivers for it unplugged.

2022-10-07vfio: Hold a reference to the iommu_group in kvm for SPAPRJason Gunthorpe1-2/+4
SPAPR exists completely outside the normal iommu driver framework, the groups it creates are fake and are only created to enable VFIO's uAPI. Thus, it does not need to follow the iommu core rule that the iommu_group will only be touched while a driver is attached. Carry a group reference into KVM and have KVM directly manage the lifetime of this object independently of VFIO. This means KVM no longer relies on the vfio group file being valid to maintain the group reference.

2022-10-07virtio-net: use mtu size as buffer length for big packetsGavin Li1-13/+24
Currently add_recvbuf_big() allocates MAX_SKB_FRAGS segments for big packets even when GUEST_* offloads are not present on the device. However, if guest GSO is not supported, it would be sufficient to allocate segments to cover just up the MTU size and no further. Allocating the maximum amount of segments results in a large waste of buffer space in the queue, which limits the number of packets that can be buffered and can result in reduced performance. Therefore, if guest GSO is not supported, use the MTU to calculate the optimal amount of segments required. Below is the iperf TCP test results over a Mellanox NIC, using vDPA for 1 VQ, queue size 1024, before and after the change, with the iperf server running over the virtio-net interface. MTU(Bytes)/Bandwidth (Gbit/s) Before After 1500 22.5 22.4 9000 12.8 25.9 And result of queue size 256. MTU(Bytes)/Bandwidth (Gbit/s) Before After 9000 2.15 11.9 With this patch no degradation is observed with multiple below tests and feature bit combinations. Results are summarized below for q depth of 1024. Interface MTU is 1500 if MTU feature is disabled. MTU is set to 9000 in other tests.

2022-10-07mmc: sdhci-tegra: Use actual clock rate for SW tuning correctionPrathamesh Shete1-1/+1
Ensure tegra_host member "curr_clk_rate" holds the actual clock rate instead of requested clock rate for proper use during tuning correction algorithm. Actual clk rate may not be the same as the requested clk frequency depending on the parent clock source set. Tuning correction algorithm depends on certain parameters which are sensitive to current clk rate. If the host clk is selected instead of the actual clock rate, tuning correction algorithm may end up applying invalid correction, which could result in errors Fixes: ea8fc5953e8b ("mmc: tegra: update hw tuning process") Signed-off-by: Aniruddha TVS Rao <[email protected]> Signed-off-by: Prathamesh Shete <[email protected]> Acked-by: Adrian Hunter <[email protected]> Acked-by: Thierry Reding <[email protected]> Cc: [email protected] Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Ulf Hansson <[email protected]>

2022-10-07mmc: renesas_sdhi: Fix rounding errorsBiju Das1-3/+18
Due to clk rounding errors on RZ/G2L platforms, it selects a clock source with a lower clock rate compared to a higher one. For eg: The rounding error (533333333 Hz / 4 * 4 = 533333332 Hz < 5333333 33 Hz) selects a clk source of 400 MHz instead of 533.333333 MHz. This patch fixes this issue by adding a margin of (1/1024) higher to the clock rate.

2022-10-07xen/pcifront: move xenstore config scanning into sub-functionJuergen Gross1-106/+37
pcifront_try_connect() and pcifront_attach_devices() share a large chunk of duplicated code for reading the config information from Xenstore, which only differs regarding calling pcifront_rescan_root() or pcifront_scan_root(). Put that code into a new sub-function. It is fine to always call pcifront_rescan_root() from that common function, as it will fallback to pcifront_scan_root() if the domain/bus combination isn't known yet (and pcifront_scan_root() should never be called for an already known domain/bus combination anyway). In order to avoid duplicate messages for the fallback case move the check for domain/bus not known to the beginning of pcifront_rescan_root(). While at it fix the error reporting in case the root-xx node had the wrong format. As the return value of pcifront_try_connect() and pcifront_attach_devices() are not used anywhere make those functions return void. As an additional bonus this removes the dubious return of -EFAULT in case of an unexpected driver state.

2022-10-06drm/amdgpu: Correct amdgpu_amdkfd_total_mem_size calculationPhilip Yang1-3/+3
amdkfd_total_mem_size is the size of total GPUs vram plus system memory to estimate page tables memory usage and leave enough VRAM room for page tables allocation. Calculate amdkfd_total_mem_size in amdgpu_amdkfd_device_probe is incorrect because adev->gmc.real_vram_size is still 0 called from amdgpu_device_ip_early_init. Move the calculation to amdgpu_amdkfd_device_init to get the correct VRAM size. Do reverse calculation in amdgpu_amdkfd_device_fini_sw to support hot-unplugging GPUs.

2022-10-06drm/amdgpu: Fix VRAM BO swap issueArunpravin Paneer Selvam1-5/+12
DRM buddy manager allocates the contiguous memory requests in a single block or multiple blocks. So for the ttm move operation (incase of low vram memory) we should consider all the blocks to compute the total memory size which compared with the struct ttm_resource num_pages in order to verify that the blocks are contiguous for the eviction process. v2: Added a Fixes tag v3: Rewrite the code to save a bit of calculations and variables (Christian) Fixes: c9cad937c0c5 ("drm/amdgpu: add drm buddy support to amdgpu") Signed-off-by: Arunpravin Paneer Selvam <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
