[PATCH v2 char-misc-next 0/7] Virtio-over-PCIe on non-MIC
From: Vincent Whitchurch
Date: Fri Feb 22 2019 - 10:31:34 EST
This allows the drivers/misc/mic/vop/ code to be used on other architectures
and adds a loopback driver to be able to use/test/evaluate it without special
hardware.
See v1 for more info:
https://lore.kernel.org/lkml/20190116163253.23780-1-vincent.whitchurch@xxxxxxxx/
v2:
- Rebase on top of the patches which have merged
- Use unsigned long instead of uintptr_t
- Drop "Use consistent DMA" for now since it's not needed for loopback
- Add race fix
- Build on all architectures, not just ARM and x86
- Add sample userspace code
Vincent Whitchurch (7):
mic: vop: Cast pointers to unsigned long
mic: Rename ioremap pointer to remap
mic: vop: Allow building on more systems
mic: vop: Add loopback driver
mic: vop: Fix init race with shared interrupts
samples: mic: Split out vop code from mpssd
samples: mic: Add sample VOP userspace
