staging: android: Delete the 'vsoc' driver

2020-02-10T16:51:12+00:00

The 'vsoc' driver was required for an early iteration of the Android
'cuttlefish' virtual platform, but this platform has been wholly
converted to use virtio drivers instead. Delete this old driver.

staging: Android: Add 'vsoc' driver for cuttlefish.

2018-04-23T12:51:37+00:00

The cuttlefish system is a virtual SoC architecture based on QEMU. It
uses the QEMU ivshmem feature to share memory regions between guest and
host with a custom protocol.

2015-12-14T19:05:45+00:00

 - remove CONFIG_SW_SYNC_USER, it is used only for testing/debugging and
   should not be upstreamed.
 - port CONFIG_SW_SYNC_USER tests interfaces to use debugfs somehow
 - port libsync tests to kselftest
 - clean up and ABI check for security issues
 - move the sync framework to drivers/base/dma-buf

staging/android: Update ION TODO per LPC discussion

2015-09-13T16:28:27+00:00

We discussed a bit with the folks on the Cc: list below what to do
with ION. Two big take-aways:

- High-performance drivers (like gpus) always want to play tricks with
  coherency and will lie to the dma api (radeon, nouveau, i915 gpu
  drivers all do so in upstream). What needs to be done here is fill
  gaps in dma-buf so that we can do this without breaking the dma-api
  expections of other clients like v4l. The consesus is that hw won't
  stop needing these tricks anytime soon.

- Placement constraints for shared buffers won't be solved any other
  way than through something platform-specific like ion with
  platform-specific knowledge in userspace in something like gralloc.
  For general-purpose devices where this assumption would be painful
  for userspace (like servers) the consensus is that such devices will
  have proper MMUs where placement constraint handling is fairly
  irrelevant.

Hence it is reasonable to destage ion as-is without changing the
overall design to enable these use-cases and just fixing up a these
few fairly minor things. Since there won't relly be an open-source
userspace for ion (and hence drm maintainers won't take it) the
proposal is to eventually move it to drivers/android/ion.[hc]. Laura
would be ok with being maintainer once this is all done and ion is
destaged.

Note that Thiago is working on exposing the cpu cache flushing for
cpu access from userspace through mmaps so this is alread in progress.
Also adding him to the Cc: list.

v2: Add ION_IOC_IMPORT to the list of ioctl that probably should go.
