8 years agodrm/fb_cma_helper: Remove implicit call to disable_unused_functions

drm/fb_cma_helper: Remove implicit call to disable_unused_functions

The drm_fbdev_cma_init function always calls the
drm_helper_disable_unused_functions. Since it's part of the usual probe
process, all the drivers using that helper will end up having their encoder
and CRTC disable functions called at probe if their device has not been
reported as enabled.

This could be fixed by reading out from the registers the current state of
the device if it is enabled, but even that will not handle the case where
the device is actually disabled.

Moreover, the drivers using the atomic modesetting expect that their enable
and disable callback to be called when the device is already enabled or
disabled (respectively).

We can however fix this issue by moving the call to
drm_helper_disable_unused_functions out of drm_fbdev_cma_init and make the
drivers needing it (all the drivers calling drm_fbdev_cma_init and not
using the atomic modesetting) explicitly call it.

drm: Do not set connector->encoder in drivers

An encoder is associated with a connector by the DRM core as a result of
setting up a configuration. Drivers using the atomic or legacy helpers
should never set up this link, even if it is a static one.

While at it, try to catch this kind of error in the future by adding a
WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't
cover all the cases, since drivers could set this up after attaching.
Drivers that use the atomic helpers will get a warning later on, though,
so hopefully the two combined cover enough to help people avoid this in
the future.

The reason is that invalid drm_file object could be accessed by
send_vblank_event function when finishing page flip if the drm_file
object was removed by drm_release and there was a pended page
flip event which was already committed to hardware.

So this patch makes the pended page flip event to be cancelled by
preclose callback which is called at front of drm_release function.

Changelog v2:
- free vblank event objects belonging to the request process,
  increment event space and decrease pending_update when cancelling
  the event

apple-gmux: Add initial documentation

Document what I've learned so far about the gmux so that we can
collaboratively reverse-engineer its remaining unknown bits
without everyone having to start from scratch.

The DOC sections are bound together in the gpu.tmpl DocBook
under a new vga_switcheroo "Handlers" chapter. Eventually
this should be amended with documentation about the four other
handlers that exist so far (nouveau v1 DSM, nouveau Optimus DSM,
radeon ATPX, amdgpu ATPX).

Requires kernel-doc with asciidoc support.

The EFI variable was reverse-engineered by Bruno Bierbaumer
<bruno@bierbaumer.net> and Andreas Heider <andreas@meetr.de>.

Some of the remaining open questions:

* How are vblank intervals synchronized on retinas to achieve seamless
  switching? Is the DP mux capable of this? It's not mentioned in the
  data sheets. Or is it done at the OS level, i.e. do we have to
  synchronize vblank intervals between DRM drivers? There's a signal
  coming from the panel connector and going into gmux, could this be
  the vblank signal as received by the panel to properly time the
  switch?

* On retinas there's an I2C bus between gmux and the connector of the
  right I/O board, apparently leading to the Parade PS8401A HDMI
  repeater. What is this for, is it controlled via gmux registers?
  Data sheet:
  http://www.paradetech.com/products/jitter-cleaning-repeaters/ps8401/

* On retinas there's an I2C bus between gmux and the LED driver.
  Pre-retinas connected the LED driver to SMBUS. Are there additional
  gmux registers on retinas to control it?

* The MacPro6,1 2013 also has a gmux, the same Renesas R4F2113 as the
  retina MacBook Pro. The Mac Pro doesn't have a built-in display,
  so what is its purpose? Power control of the dual FirePro GPUs?
  Switching of the external DP/Thunderbolt ports? The iFixit teardown
  clearly shows one TI HD3SS212 DisplayPort mux on the logic board next
  to one of the three Thunderbolt controllers. However six muxes would
  be necessary to switch all six ports between GPUs. The mux is probably
  necessary for one of the display configurations allowed by Apple,
  but which one?

* Registers we haven't decoded yet:
  0x700 32 Bit configmap?
  0x708 32 Bit power sequence?
  0x712  8 Bit status of clock from panel on retinas?

  "Missing is also precise knowledge as to what the gmux depends on.
  From behavioral reports, it is somehow sensitive to VGA IO/MEM
  routing (it apparently needs the routing to go to integrated GPU,
  not discrete GPU).
  When the routing is inappropriate backlight control IO just reads back

drm/nouveau/instmem/gk20a: use DMA API CPU mapping

Commit 69c4938249fb ("drm/nouveau/instmem/gk20a: use direct CPU access")
tried to be smart while using the DMA-API by managing the CPU mappings of
buffers allocated with the DMA-API by itself. In doing so, it relied
on dma_to_phys() which is an architecture-private function not
available everywhere. This broke the build on several architectures.

Since there is no reliable and portable way to obtain the physical
address of a DMA-API buffer, stop trying to be smart and just use the
CPU mapping that the DMA-API can provide. This means that buffers will
be CPU-mapped for all their life as opposed to when we need them, but
anyway using the DMA-API here is a fallback for when no IOMMU is
available so we should not expect optimal behavior.

This makes the IOMMU and DMA-API implementations of instmem diverge
enough that we should maybe put them into separate files...
