4 years agodrm/managed: Cleanup of unused functions and polishing docs
Daniel Vetter [Wed, 2 Sep 2020 07:26:27 +0000 (09:26 +0200)]
drm/managed: Cleanup of unused functions and polishing docs

Following functions are only used internally, not by drivers:
- devm_drm_dev_init

Also, now that we have a very slick and polished way to allocate a
drm_device with devm_drm_dev_alloc, update all the docs to reflect the
new reality. Mostly this consists of deleting old and misleading
hints. Two main ones:

- it is no longer required that the drm_device base class is first in
  the structure. devm_drm_dev_alloc can cope with it being anywhere

- obviously embedded now strongly recommends using devm_drm_dev_alloc

v2: Fix typos (Noralf)

v3: Split out the removal of drm_dev_init, that's blocked on some
discussions on how to convert vgem/vkms/i915-selftests. Adjust commit
message to reflect that.

4 years agodrm: Replace mode->export_head with a boolean
Ville Syrjälä [Tue, 28 Apr 2020 17:19:40 +0000 (20:19 +0300)]
drm: Replace mode->export_head with a boolean

In order to shrink drm_display_mode below the magic two cacheline
mark in 64bit we need to shrink it by another 8 bytes. The easiest
thing to eliminate is the 'export_head' list head which is only
used during the getconnector ioctl to temporarly track which modes
on the connector's mode list are to be exposed and which are to
remain hidden.

We can simply replace the list head with a boolean which we use
to tag the modes that are to be exposed. If we make sure to clear
the tags after we're done with them we don't even need an extra
loop over the modes to reset the tags at the start of the
getconnector ioctl.

Conveniently we already have a hole for the boolean left
behind by the removal of mode->private_flags. The final size
of the struct is now 112 bytes on 32bit and 120 bytes on 64bit.

Another alternative would be a temp bitmask so we wouldn't have
to have anything in the mode struct itself. The main issue is
how large of a bitmask do we need? I guess we could allocate
it dynamically but that means an extra kcalloc() and an extra
loop through the modes to count them first (or grow the bitmask
with krealloc() as needed).

Sam McNally [Mon, 27 Jul 2020 06:03:37 +0000 (16:03 +1000)]
drm/dp_mst: Support remote i2c writes

For DP MST outputs, the i2c device currently only supports transfers
that can be implemented using remote i2c reads. Such transfers must
consist of zero or more write transactions followed by one read
transaction. DDC/CI commands require standalone write transactions and
hence aren't supported.

Since each remote i2c write is handled as a separate transfer, remote
i2c writes can support transfers consisting of write transactions, where
all but the last have I2C_M_STOP set. According to the DDC/CI 1.1
standard, DDC/CI commands only require a single write or read
transaction in a transfer, so this is sufficient.

For i2c transfers meeting the above criteria, generate and send a remote
i2c write message for each transaction. Add the trivial remote i2c write
reply parsing support so remote i2c write acks bubble up correctly.

Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().
