vfio/platform: Mark reset drivers for removal

2025-09-19T20:36:38Z

While vfio-platform itself is on a reprieve from being removed[1], these reset drivers don't support any current hardware, are not being tested, and suggest a level of support that doesn't really exist. Mark them for removal to surface any remaining user such that we can potentially drop them and simplify the code if none appear.

vfio/platform: Cleanup Kconfig

2023-06-16T18:23:50Z

Like vfio-pci, there's also a base module here where vfio-amba depends on vfio-platform, when really it only needs vfio-platform-base. Create a sub-menu for platform drivers and a nested menu for reset drivers. Cleanup Makefile to make use of new CONFIG_VFIO_PLATFORM_BASE for building the shared modules and traversing reset modules.

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: platform: reset: AMD xgbe reset module

2015-11-03T19:55:21Z

This patch introduces a module that registers and implements a low-level reset function for the AMD XGBE device. it performs the following actions: - reset the PHY - disable auto-negotiation - disable & clear auto-negotiation IRQ - soft-reset the MAC Those tiny pieces of code are inherited from the native xgbe driver.

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
