2023-06-27pds_vdpa: add support for vdpa and vdpamgmt interfacesShannon Nelson6-2/+892
This is the vDPA device support, where we advertise that we can support the virtio queues and deal with the configuration work through the pds_core's adminq.

2023-06-27pds_vdpa: add vdpa config client commandsShannon Nelson4-1/+236
These are the adminq commands that will be needed for setting up and using the vDPA device. There are a number of commands defined in the FW's API, but by making use of the FW's virtio BAR we only need a few of these commands for vDPA support.

2023-06-27pds_vdpa: Add new vDPA driver for AMD/Pensando DSCShannon Nelson6-0/+144
This is the initial auxiliary driver framework for a new vDPA device driver, an auxiliary_bus client of the pds_core driver. The pds_core driver supplies the PCI services for the VF device and for accessing the adminq in the PF device. This patch adds the very basics of registering for the auxiliary device and setting up debugfs entries.

2023-06-27virtio: allow caller to override device DMA mask in vp_modernShannon Nelson1-1/+2
To add a bit of vendor flexibility with various virtio based devices, allow the caller to specify a different DMA mask. This adds a dma_mask field to struct virtio_pci_modern_device. If defined by the driver, this mask will be used in a call to dma_set_mask_and_coherent() instead of the traditional DMA_BIT_MASK(64). This allows limiting the DMA space on vendor devices with address limitations.

2023-06-27virtio: allow caller to override device id in vp_modernShannon Nelson1-11/+19
To add a bit of vendor flexibility with various virtio based devices, allow the caller to check for a different device id. This adds a function pointer field to struct virtio_pci_modern_device to specify an override device id check. If defined by the driver, this function will be called to check that the PCI device is the vendor's expected device, and will return the found device id to be stored in mdev->id.device. This allows vendors with alternative vendor device ids to use this library on their own device BAR. Note: A lot of the diff in this is simply indenting the existing code into an else block.

2023-06-27virtio_pci: Optimize virtio_pci_device structure sizeFeng Liu1-3/+4
Improve the size of the virtio_pci_device structure, which is commonly used to represent a virtio PCI device. A given virtio PCI device can either of legacy type or modern type, with the struct virtio_pci_legacy_device occupying 32 bytes and the struct virtio_pci_modern_device occupying 88 bytes. Make them a union, thereby save 32 bytes of memory as shown by the pahole tool. This improvement is particularly beneficial when dealing with numerous devices, as it helps conserve memory resources. Before the modification, pahole tool reported the following: struct virtio_pci_device { [...] struct virtio_pci_legacy_device ldev; /* 824 32 */ /* --- cacheline 13 boundary (832 bytes) was 24 bytes ago --- */ struct virtio_pci_modern_device mdev; /* 856 88 */ /* XXX last struct has 4 bytes of padding */ [...] /* size: 1056, cachelines: 17, members: 19 */ [...] }; After the modification, pahole tool reported the following: struct virtio_pci_device { [...] union { struct virtio_pci_legacy_device ldev; /* 824 32 */ struct virtio_pci_modern_device mdev; /* 824 88 */ }; /* 824 88 */ [...] /* size: 1024, cachelines: 16, members: 18 */ [...] }; Signed-off-by: Feng Liu <feliu@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Message-Id: <20230516135446.16266-1-feliu@nvidia.com> Signed-off-by: Michael S.

2023-06-21Revert "virtio-blk: support completion batching for the IRQ path"Michael S. Tsirkin1-45/+37
This reverts commit 07b679f70d73483930e8d3c293942416d9cd5c13. This change appears to have broken things... We now see applications hanging during disk accesses. e.g. multi-port virtio-blk device running in h/w (FPGA) Host running a simple 'fio' test. [global] thread=1 direct=1 ioengine=libaio norandommap=1 group_reporting=1 bs=4K rw=read iodepth=128 runtime=1 numjobs=4 time_based [job0] filename=/dev/vda [job1] filename=/dev/vdb [job2] filename=/dev/vdc ... [job15] filename=/dev/vdp i.e. 16 disks; 4 queues per disk; simple burst of 4KB reads This is repeatedly run in a loop. After a few, normally <10 seconds, fio hangs. With 64 queues (16 disks), failure occurs within a few seconds; with 8 queues (2 disks) it may take ~hour before hanging. Last message: fio-3.19 Starting 8 threads Jobs: 1 (f=1): [_(7),R(1)][68.3%][eta 03h:11m:06s] I think this means at the end of the run 1 queue was left incomplete. 'diskstats' (run while fio is hung) shows no outstanding transactions. e.g. $ cat /proc/diskstats ... 252 0 vda 1843140071 0 14745120568 712568645 0 0 0 0 0 3117947 712568645 0 0 0 0 0 0 252 16 vdb 1816291511 0 14530332088 704905623 0 0 0 0 0 3117711 704905623 0 0 0 0 0 0 ... Other stats (in the h/w, and added to the virtio-blk driver ([a]virtio_queue_rq(), [b]virtblk_handle_req(), [c]virtblk_request_done()) all agree, and show every request had a completion, and that virtblk_request_done() never gets called. e.g. PF= 0 vq=0 1 2 3 [a]request_count - 839416590 813148916 105586179 84988123 [b]completion1_count - 839416590 813148916 105586179 84988123 [c]completion2_count - 0 0 0 0 PF= 1 vq=0 1 2 3 [a]request_count - 823335887 812516140 104582672 75856549 [b]completion1_count - 823335887 812516140 104582672 75856549 [c]completion2_count - 0 0 0 0 i.e. the issue is after the virtio-blk driver. This change was introduced in kernel 6.3.0. I am seeing this using 6.3.3. If I run with an earlier kernel (5.15), it does not occur. If I make a simple patch to the 6.3.3 virtio-blk driver, to skip the blk_mq_add_to_batch()call, it does not fail. e.g. kernel 5.15 - this is OK virtio_blk.c,virtblk_done() [irq handler] if (likely(!blk_should_fake_timeout(req->q))) { blk_mq_complete_request(req); } kernel 6.3.3 - this fails virtio_blk.c,virtblk_handle_req() [irq handler] if (likely(!blk_should_fake_timeout(req->q))) { if (!blk_mq_complete_request_remote(req)) { if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) { virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed } } } If I do, kernel 6.3.3 - this is OK virtio_blk.c,virtblk_handle_req() [irq handler] if (likely(!blk_should_fake_timeout(req->q))) { if (!blk_mq_complete_request_remote(req)) { virtblk_request_done(req); //force this here... if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) { virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed } } } Perhaps you might like to fix/test/revert this change...

2023-06-20regmap: spi-avmm: Fix regmap_bus max_raw_writeRuss Weight1-1/+1
The max_raw_write member of the regmap_spi_avmm_bus structure is defined as: .max_raw_write = SPI_AVMM_VAL_SIZE * MAX_WRITE_CNT SPI_AVMM_VAL_SIZE == 4 and MAX_WRITE_CNT == 1 so this results in a maximum write transfer size of 4 bytes which provides only enough space to transfer the address of the target register. It provides no space for the value to be transferred. This bug became an issue (divide-by-zero in _regmap_raw_write()) after the following was accepted into mainline: commit 3981514180c9 ("regmap: Account for register length when chunking") Change max_raw_write to include space (4 additional bytes) for both the register address and value: .max_raw_write = SPI_AVMM_REG_SIZE + SPI_AVMM_VAL_SIZE * MAX_WRITE_CNT Fixes: 7f9fb67358a2 ("regmap: add Intel SPI Slave to AVMM Bus Bridge support") Reviewed-by: Matthew Gerlach <matthew.gerlach@linux.intel.com> Signed-off-by: Russ Weight <russell.h.weight@intel.com> Link: https://lore.kernel.org/r/20230620202824.380313-1-russell.h.weight@intel.com Signed-off-by: Mark Brown <broonie@kernel.org>

2023-06-20net: dsa: introduce preferred_default_local_cpu_port and use on MT7530Vladimir Oltean1-0/+15
Since the introduction of the OF bindings, DSA has always had a policy that in case multiple CPU ports are present in the device tree, the numerically smallest one is always chosen. The MT7530 switch family, except the switch on the MT7988 SoC, has 2 CPU ports, 5 and 6, where port 6 is preferable on the MT7531BE switch because it has higher bandwidth. The MT7530 driver developers had 3 options: - to modify DSA when the MT7531 switch support was introduced, such as to prefer the better port - to declare both CPU ports in device trees as CPU ports, and live with the sub-optimal performance resulting from not preferring the better port - to declare just port 6 in the device tree as a CPU port Of course they chose the path of least resistance (3rd option), kicking the can down the road. The hardware description in the device tree is supposed to be stable - developers are not supposed to adopt the strategy of piecemeal hardware description, where the device tree is updated in lockstep with the features that the kernel currently supports. Now, as a result of the fact that they did that, any attempts to modify the device tree and describe both CPU ports as CPU ports would make DSA change its default selection from port 6 to 5, effectively resulting in a performance degradation visible to users with the MT7531BE switch as can be seen below. Without preferring port 6: [ ID][Role] Interval Transfer Bitrate Retr [ 5][TX-C] 0.00-20.00 sec 374 MBytes 157 Mbits/sec 734 sender [ 5][TX-C] 0.00-20.00 sec 373 MBytes 156 Mbits/sec receiver [ 7][RX-C] 0.00-20.00 sec 1.81 GBytes 778 Mbits/sec 0 sender [ 7][RX-C] 0.00-20.00 sec 1.81 GBytes 777 Mbits/sec receiver With preferring port 6: [ ID][Role] Interval Transfer Bitrate Retr [ 5][TX-C] 0.00-20.00 sec 1.99 GBytes 856 Mbits/sec 273 sender [ 5][TX-C] 0.00-20.00 sec 1.99 GBytes 855 Mbits/sec receiver [ 7][RX-C] 0.00-20.00 sec 1.72 GBytes 737 Mbits/sec 15 sender [ 7][RX-C] 0.00-20.00 sec 1.71 GBytes 736 Mbits/sec receiver Using one port for WAN and the other ports for LAN is a very popular use case which is what this test emulates. As such, this change proposes that we retroactively modify stable kernels (which don't support the modification of the CPU port assignments, so as to let user space fix the problem and restore the throughput) to keep the mt7530 driver preferring port 6 even with device trees where the hardware is more fully described.

All MT7530 switch IP variants share the MT7530_MFC register, but the current driver only writes it for the switch variant that is integrated in the MT7621 SoC. Modify the code to include all MT7530 derivatives.

2023-06-20net: dsa: mt7530: set all CPU ports in MT7531_CPU_PMAPArınç ÜNAL2-7/+9
MT7531_CPU_PMAP represents the destination port mask for trapped-to-CPU frames (further restricted by PCR_MATRIX). Currently the driver sets the first CPU port as the single port in this bit mask, which works fine regardless of whether the device tree defines port 5, 6 or 5+6 as CPU ports. This is because the logic coincides with DSA's logic of picking the first CPU port as the CPU port that all user ports are affine to, by default. An upcoming change would like to influence DSA's selection of the default CPU port to no longer be the first one, and in that case, this logic needs adaptation. Since there is no observed leakage or duplication of frames if all CPU ports are defined in this bit mask, simply include them all.
