in the HVS scanning out garbage or just halting.

8 years agodrm/i915: Set aux.dev to the drm_connector device, instead of drm_device.
Rafael Antognolli [Thu, 21 Jan 2016 23:10:20 +0000 (15:10 -0800)]
drm/i915: Set aux.dev to the drm_connector device, instead of drm_device.

So far, the i915 driver and some other drivers set it to the drm_device,
which doesn't allow one to know which DP a given aux channel is related
to. Changing this to be the drm_connector provides proper nesting, still
allowing one to get the drm_device from it. Some drivers already set it
to the drm_connector.

This also removes the need to add a sysfs link for the i2c device under
the connector, as it will already be there.

v9:
 - As a side effect, drm_dp_aux_unregister() must be called before
 intel_connector_unregister(), as both the aux.dev and the i2c adapter
 dev are children of the drm_connector device now. Calling
 drm_dp_aux_unregister() before prevents them from being destroyed
 twice.

v10:
 - move aux_fini() to connector_unregister(), instead of moving
 drm_dp_aux_unregister() outside of connector_register().

circumvent this problem there are begin/end coherency markers, that forward
directly to existing dma-buf device drivers vfunc hooks. Userspace can make use

used like following:

     - for each drawing/upload cycle in CPU 1. SYNC_START ioctl, 2. read/write
       to mmap area 3. SYNC_END ioctl. This can be repeated as often as you

v2 (Tiago): Fix header file type names (u64 -> __u64)
v3 (Tiago): Add documentation. Use enum dma_buf_sync_flags to the begin/end
dma-buf functions. Check for overflows in start/length.
v4 (Tiago): use 2d regions for sync.
v5 (Tiago): forget about 2d regions (v4); use _IOW in DMA_BUF_IOCTL_SYNC and
remove range information from struct dma_buf_sync.
v6 (Tiago): use __u64 structured padded flags instead enum. Adjust
documentation about the recommendation on using sync ioctls.
v7 (Tiago): Alex' nit on flags definition and being even more wording in the
doc about sync usage.
v9 (Tiago): remove useless is_dma_buf_file check. Fix sync.flags conditionals
and its mask order check. Add <linux/types.h> include in dma-buf.h.
