virtio: wrap config->reset calls

2022-01-14T23:50:52+00:00

This will enable cleanups down the road. The idea is to disable cbs, then add "flush_queued_cbs" callback as a parameter, this way drivers can flush any work queued after callbacks have been disabled. Signed-off-by: Michael S.

virtio-input: add multi-touch support

2021-02-23T12:52:59+00:00

Without multi-touch slots allocated, ABS_MT_SLOT events will be lost by input_handle_abs_event. Implementation is based on uinput_create_device.

virtio_input: Prevent EV_MSC/MSC_TIMESTAMP loop storm for MT.

2021-02-23T12:52:59+00:00

In 'commit 29cc309d8bf1 ("HID: hid-multitouch: forward MSC_TIMESTAMP")', EV_MSC/MSC_TIMESTAMP is added to each before EV_SYN event. EV_MSC is configured as INPUT_PASS_TO_ALL. In case of a touch device which report MSC_TIMESTAMP: BE pass EV_MSC/MSC_TIMESTAMP to FE on receiving event from evdev. FE pass EV_MSC/MSC_TIMESTAMP back to BE. BE writes EV_MSC/MSC_TIMESTAMP to evdev due to INPUT_PASS_TO_ALL. BE receives extra EV_MSC/MSC_TIMESTAMP and pass to FE. >>> Each new frame becomes larger and larger. Disable EV_MSC/MSC_TIMESTAMP forwarding for MT. V2: Rebase. Signed-off-by: Colin Xu Link: https://lore.kernel.org/r/20210202001923.6227-1-colin.xu@intel.com Signed-off-by: Michael S.

virtio_input: Constify id_table

id_table is not modified, so make it const to allow the compiler to put it in read-only memory. Signed-off-by: Rikard Falkeborn Link: https://lore.kernel.org/r/20200911203509.26505-3-rikard.falkeborn@gmail.com Signed-off-by: Michael S. Tsirkin Reviewed-by: David Hildenbrand

virtio: wrap find_vqs

We are going to add more parameters to find_vqs, let's wrap the call so we don't need to tweak all drivers every time. Signed-off-by: Michael S. Tsirkin

virtio: allow drivers to request IRQ affinity when creating VQs

2017-02-27T18:54:04+00:00

Add a struct irq_affinity pointer to the find_vqs methods, which if set is used to tell the PCI layer to create the MSI-X vectors for our I/O virtqueues with the proper affinity from the start. Compared to after the fact affinity hints this gives us an instantly working setup and allows to allocate the irq descritors node-local and avoid interconnect traffic. Last but not least this will allow blk-mq queues are created based on the interrupt affinity for storage drivers. Signed-off-by: Christoph Hellwig Reviewed-by: Jason Wang Signed-off-by: Michael S.

virtio: make find_vqs() checkpatch.pl-friendly

2016-01-12T18:47:06+00:00

checkpatch.pl wants arrays of strings declared as follows: static const char * const names[] = { "vq-1", "vq-2", "vq-3" }; Currently the find_vqs() function takes a const char *names[] argument so passing checkpatch.pl's const char * const names[] results in a compiler error due to losing the second const. This patch adjusts the find_vqs() prototype and updates all virtio transports. This makes it possible for virtio_balloon.c, virtio_input.c, virtgpu_kms.c, and virtio_rpmsg_bus.c to use the checkpatch.pl-friendly type. Signed-off-by: Stefan Hajnoczi Signed-off-by: Michael S.
