This patch moves next from vring_desc_state_packed to vring_desc_desc_extra_packed. This makes it simpler to let extra state to be reused by split virtqueue. Signed-off-by:

After device reset, the virtqueues are not ready so clear the ready field. Failing to do so can result in virtio_vdpa failing to load if the device was previously used by vhost_vdpa and the old values are ready. virtio_vdpa expects to find VQs in "not ready" state.

There are currently two cases where we poll TX vq not in response to a callback: start xmit and rx napi. We currently do this with callbacks enabled which can cause extra interrupts from the card. Used not to be a big issue as we run with interrupts disabled but that is no longer the case, and in some cases the rate of spurious interrupts is so high linux detects this and actually kills the interrupt. Fix up by disabling the callbacks before polling the tx vq. Signed-off-by:

virtio_disable_cb is currently a nop for split ring with event index. This is because it used to be always called from a callback when we know device won't trigger more events until we update the index. However, now that we run with interrupts enabled a lot we also poll without a callback so that is different: disabling callbacks will help reduce the number of spurious interrupts. Further, if using event index with a packed ring, and if being called from a callback, we actually do disable interrupts which is unnecessary. Fix both issues by tracking whenever we get a callback. If that is the case disabling interrupts with event index can be a nop. If not the case disable interrupts. Note: with a split ring there's no explicit "no interrupts" value. For now we write a fixed value so our chance of triggering an interupt is 1/ring size. It's probably better to write something related to the last used index there to reduce the chance even further. For now I'm keeping it simple. Signed-off-by: -

We currently check num_free outside tx q lock which is unsafe: new packets can arrive meanwhile and there won't be space in the queue. Thus a spurious queue wakeup causing overhead and even packet drops. Move the check under the lock to fix that. Signed-off-by: -

It's unsafe to operate a vq from multiple threads. Unfortunately this is exactly what we do when invoking clean tx poll from rx napi. Same happens with napi-tx even without the opportunistic cleaning from the receive interrupt: that races with processing the vq in start_xmit. As a fix move everything that deals with the vq to under tx lock. Fixes: b92f1e67 ("virtio-net: transmit napi") Signed-off-by:

In order to support running vdpa using vritio_vdpa driver, we need to create a different kind of MR, one that has 1:1 mapping, since the addresses referring to virtqueues are dma addresses. We create the 1:1 MR in mlx5_vdpa_dev_add() only in case firmware supports the general capability umem_uid_0. The reason for that is that 1:1 MRs must be created with uid == 0 while virtqueue objects can be created with uid == 0 only when the firmware capability is on. If the set_map() callback is called with new translations provided through iotlb, the driver will destroy the 1:1 MR and create a regular one. Signed-off-by:

Before SF support was introduced, the DMA device was equal to mdev->device which was in essence equal to pdev->dev. With SF introduction this is no longer true. It has already been handled for vhost_vdpa since the reference to the dma device can from within mlx5_vdpa. With virtio_vdpa this broke. To fix this we set the real dma device when initializing the device. In addition, for the sake of consistency, previous references in the code to the dma device are changed to vdev->dma_dev.

Currently all resources must be created with uid != 0 which is essential when userspace processes are allocating virtquueue resources. Since this is a kernel implementation, it is perfectly legal to open resources with uid == 0. In case firmware supports, avoid allocating user context. Signed-off-by:

The vhost work flush function was flushing the entire work queue, so there is no need for the double vhost_work_dev_flush calls in vhost_scsi_flush. And we do not need to call vhost_poll_flush for each poller because that call also ends up flushing the same work queue thread the vhost_work_dev_flush call flushed. Signed-off-by:

Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.14 kernel. Not so much going on. No core changes, just drivers. The most interesting would be that MIPS Ralink is migrating to pin control and we have some bindings but not yet code for the Apple M1 pin controller. New drivers: - Last merge window we created a driver for the Ralink RT2880. We are now moving the Ralink SoC pin control drivers out of the MIPS architecture code and into the pin control subsystem. This concerns RT288X, MT7620, RT305X, RT3883 and MT7621. - Qualcomm SM6125 SoC pin control driver. - Qualcomm spmi-gpio support for PM7325. - Qualcomm spmi-mpp also handles PMI8994 (just a compatible string) - Mediatek MT8365 SoC pin controller. - New device HID for the AMD GPIO controller. Improvements: - Pin bias config support for a slew of Renesas pin controllers. - Incremental improvements and non-urgent bug fixes to the Renesas SoC drivers. - Implement irq_set_wake on the AMD pin controller so we can wake up from external pin events.

Pull clk updates from Stephen Boyd: "This round has a diffstat dominated by Qualcomm clk drivers. Honestly though that's just a bunch of data so the diffstat reflects that. Looking beyond that there's just a bunch of updates all around in various clk drivers. Renesas and NXP (for i.MX) are two SoC vendors that have a lot of patches in here. Overall the driver changes look to be mostly enabling more clks and non-critical fixes that we could hold until the next merge window.
