vfio: Use kconfig if XX/endif blocks instead of repeating 'depends on'

2021-08-26T16:36:51Z

This results in less kconfig wordage and a simpler understanding of the required "depends on" to create the menu structure. The next patch increases the nesting level a lot so this is a nice preparatory simplification.

vfio: Use select for eventfd

2021-08-26T16:36:51Z

If VFIO_VIRQFD is required then turn on eventfd automatically. The majority of kconfig users of the EVENTFD use select not depends on.

ARM: amba: Allow some ARM_AMBA users to compile with COMPILE_TEST

2021-03-16T16:39:28Z

CONFIG_VFIO_AMBA has a light use of AMBA, adding some inline fallbacks when AMBA is disabled will allow it to be compiled under COMPILE_TEST and make VFIO easier to maintain.

vfio-platform: Add COMPILE_TEST to VFIO_PLATFORM

x86 can build platform bus code too, so vfio-platform and all the platform reset implementations compile successfully on x86. Signed-off-by: Jason Gunthorpe Message-Id: <2-v1-df057e0f92c3+91-vfio_arm_compile_test_jgg@nvidia.com> Signed-off-by: Alex Williamson

VFIO: platform: Calxeda xgmac reset module

2015-06-22T15:35:38Z

This patch introduces a module that registers and implements a basic reset function for the Calxeda xgmac device. This latter basically disables interrupts and stops DMA transfers. The reset function code is inherited from the native calxeda xgmac driver. Signed-off-by: Eric Auger Acked-by: Baptiste Reynal Tested-by: Baptiste Reynal Signed-off-by: Alex Williamson

vfio: Split virqfd into a separate module for vfio bus drivers

2015-03-17T14:33:38Z

An unintended consequence of commit 42ac9bd18d4f ("vfio: initialize the virqfd workqueue in VFIO generic code") is that the vfio module is renamed to vfio_core so that it can include both vfio and virqfd. That's a user visible change that may break module loading scritps and it imposes eventfd support as a dependency on the core vfio code, which it's really not. virqfd is intended to be provided as a service to vfio bus drivers, so instead of wrapping it into vfio.ko, we can make it a stand-alone module toggled by vfio bus drivers. This has the additional benefit of removing initialization and exit from the core vfio code. Signed-off-by: Alex Williamson

vfio: amba: add the VFIO for AMBA devices module to Kconfig

2015-03-16T20:08:45Z

Enable building the VFIO AMBA driver. VFIO_AMBA depends on VFIO_PLATFORM, since it is sharing a portion of the code, and it is essentially implemented as a platform device whose resources are discovered via AMBA specific APIs in the kernel.
