uio_hv_generic: Remove use of PAGE_SIZE

2024-04-11T12:55:53Z

Remove use of PAGE_SIZE for device ring buffer size calculation, as there is no dependency on device ring buffer size for linux kernel's PAGE_SIZE. Use the absolute value of 2 MB instead.

uio_hv_generic: Enable interrupt for low speed VMBus devices

2024-04-11T12:55:53Z

Hyper-V is adding some "specialty" synthetic devices. Instead of writing new kernel-level VMBus drivers for these devices, the devices will be presented to user space via this existing Hyper-V generic UIO driver, so that a user space driver can handle the device. Since these new synthetic devices are low speed devices, they don't support monitor bits and we must use vmbus_setevent() to enable interrupts from the host.

uio_hv_generic: Query the ringbuffer size for device

2024-04-11T12:55:53Z

Query the ring buffer size from pre defined table per device and use that value for allocating the ring buffer for that device. Keep the size as current default which is 2 MB if the device doesn't have any preferred ring size.

uio: use threaded interrupts

2024-04-11T12:40:29Z

Split the existing uio_interrupt into a hardirq handler and a thread function. The hardirq handler deals with the interrupt source in hardware, the thread function notifies userspace that there is an event to be handled.

uio_pdrv_genirq: convert to use device_property APIs

2024-04-11T12:40:29Z

Convert the uio_pdrv_genirq driver to use the device_property_* APIs instead of the of_property_* ones. This allows UIO interrupts to be defined via an ACPI overlay using the Device Tree namespace linkage.

uio: pruss: Remove this driver

2024-04-11T12:39:56Z

This UIO driver was used to control the PRU processors found on various TI SoCs. It was created before the Remoteproc framework, but now with that we have a standard way to program and manage the PRU processors. The proper PRU Remoteproc driver should be used instead of this driver. This driver only supported the original class of PRUSS (OMAP-L1xx / AM17xx / AM18xx / TMS320C674x / DA8xx) but when these platforms were switched to use Device Tree the support for DT was not added to this driver and so it is now unused/unusable. Support for these platforms can be added to the proper PRU Remoteproc driver if ever needed. Remove this driver.
