* vdpa: device feature provisioningJason Wang2022-10-073-0/+8
| | | | | | | | | | | | | | | | | This patch allows the device features to be provisioned through netlink. A new attribute is introduced to allow the userspace to pass a 64bit device features during device adding. This provides several advantages: - Allow to provision a subset of the features to ease the cross vendor live migration. - Better debug-ability for vDPA framework and parent.

* virtio-net: use mtu size as buffer length for big packetsGavin Li2022-10-071-13/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a guest PEBS counter is cross-mapped by a host counter, software will remove the corresponding bit in the arr[global_ctrl].guest and expect hardware to perform a change of state "from enable to disable" via the msr_slot[] switch during the vmx transaction. The real world is that if user adjust the counter overflow value small enough, it still opens a tiny race window for the previously PEBS-enabled counter to write cross-mapped PEBS records into the guest's PEBS buffer, when arr[global_ctrl].guest has been prioritised (switch_msr_special stuff) to switch into the enabled state, while the arr[pebs_enable].guest has not. Close this window by clearing invalid bits in the arr[global_ctrl].guest.

Instead of trying to make RCU-like behavior for bp_desc, just eliminate the unnecessary level of indirection of bp_desc, and hold the whole descriptor as a global. Anyhow, there is only a single descriptor at any given moment.

To prevent this, explicitly align the plug events delay with the USB4 spec value of 10ms.

As documented, the HW should stop immediately and self reset. There is likely a problem or a miss-understanding of the self reset mechanism, as unless we make a long pause, the next command will then report an error even if there is no error in it. Disabling error detection fixes the issue, and let the decoder continue after an error. This patch is safe for backport into older kernels.

This caused the encoder driver to fail probe. Since the platform_get_resource() call was only being used to check for the presence of the interrupt (its returned resource wasn't even used) and platform_get_irq() was already being used to get the IRQ, simply drop the use of platform_get_resource(IORESOURCE_IRQ) and handle the failure of platform_get_irq(), to get the driver probing again.

Don't attempt to call video_put_user() since there is no point, and it would copy back data on error even if INFO_FL_ALWAYS_COPY wasn't set. So if writing the array back to userspace fails, then don't go to out_array_args, instead just continue with the regular code that just returns the error unless 'always_copy' is set. Update the VIDIOC_G/S/TRY_EXT_CTRLS ioctls to set the ALWAYS_COPY flag since they now need it. Before this worked due to this buggy code, but now that that is fixed these ioctls need to set this flag explicitly.
