Merge branch 'drm-next-3.14-wip' of git://people.freedesktop.org/~agd5f/linux into drm-next

This is the drm-next pull for radeon for 3.14. Highlights include:
- dpm rework which fixes some issues and allows us to enable dpm by
default on CIK parts
- enable clockgating on CIK parts
- pci config reset.  This is a bus-level chip reset that can be more
reliable than soft reset in certain cases.  Disabled by default.  Enable
with the hard_reset module option.
- big endian rptr/wrptr update fixes
- lots of debugfs improvements
- some driver cleanup patches from Rashika Kheria
- bug fixes

Userspace support is already in upstream mesa.

downstream android kernel, to simplify porting of this driver to
existing devices.  These do not constitute any committed/stable
DT ABI.  The addition of proper DT bindings will be a subsequent
patch, at which point (as best as possible) I will try to support
either upstream bindings or what is found in downstream android
kernel, so that existing device DT files can be used.

Rob Clark [Sat, 30 Nov 2013 22:51:47 +0000 (17:51 -0500)]
drm/msm: add mdp5/apq8x74

Add support for the new MDP5 display controller block.  The mapping
between parts of the display controller and KMS is:

  plane   -> PIPE{RGBn,VIGn}             \
  crtc    -> LM (layer mixer)            |-> MDP "device"
  encoder -> INTF                        /
  connector -> HDMI/DSI/eDP/etc          --> other device(s)

Unlike MDP4, it appears we can get by with a single encoder, rather
than needing a different implementation for DTV, DSI, etc.  (Ie. the
register interface is same, just different bases.)

Also unlike MDP4, all the IRQs for other blocks (HDMI, DSI, etc) are
routed through MDP.

And finally, MDP5 has this "Shared Memory Pool" (called "SMP"), from
which blocks need to be allocated to the active pipes based on fetch
stride.

10 years agodrm/msm: add hdmi support for apq8x74/mdp5

drm/msm: add hdmi support for apq8x74/mdp5

The HDMI block is basically the same between older SoC's with mdp4
display controller, and newer ones with mdp5.

So mostly this consists of better abstracting out the different sets of
regulators, clks, etc.  In particular, for regulators and clks we can
split it up by what is needed for hot plug detect to work, and what is
needed to light up the display.

Also, 8x74 has a new phy.. a very simple one, but split out into a
different mmio space.  And with mdp5, the irq is shared with mdp, so we
don't directly register our own irq handler.

drm/msm: add support for non-IOMMU systems

Add a VRAM carveout that is used for systems which do not have an IOMMU.

The VRAM carveout uses CMA.  The arch code must setup a CMA pool for the
device (preferrably in highmem.. a 256m-512m VRAM pool in lowmem is not
cool).  The user can configure the VRAM pool size using msm.vram module
param.

Technically, the abstraction of IOMMU behind msm_mmu is not strictly
needed, but it simplifies the GEM code a bit, and will be useful later
when I add support for a2xx devices with GPUMMU, so I decided to keep
this part.

It appears to be possible to configure the GPU to restrict access to
addresses within the VRAM pool, but this is not done yet.  So for now
the GPU will refuse to load if there is no sort of mmu.  Once address
based limits are supported and tested to confirm that we aren't giving
the GPU access to arbitrary memory, this restriction can be lifted

drm/tegra: Changes for v3.14-rc1

This series of changes brings DRM panel support as well as initial code
to register DSI hosts and peripherals and bind them to DSI drivers. The
panel and DSI code are both used by the simple panel driver.

The Tegra-specific changes build on top of this work to add support for
various panels found on Tegra boards. New drivers enable the DSI host
found on Tegra114 and a special hardware block that calibrates the pads
used for DSI and CSI. The host1x and the display controller drivers gain
basic Tegra124 support. To round of the new features, the DRM driver now
sports a very simple PRIME implementation.

In addition there are various improvements such as the host1x API being
exported so that client drivers (like the Tegra DRM driver) can be built
as modules. HDMI now does better power management and legacy FBDEV can
now be disabled via Kconfig (though it's still enabled by default). A
few sparse warnings have been squashed and various parts of the code
have become more robust.

 Use memdup_user rather than duplicating its implementation
 This is a little bit restricted to reduce false positives

10 years agodrm: remove dev->vma_count

drm: remove dev->vma_count

This is just used for a debugfs file, and we can easily reconstruct
this number by just walking the list twice. Which isn't really bad for
a debugfs file anyway.

So let's rip this out.

There's the other issue that the dev->vmalist itself is a bit useless,
since that can be reconstructed with all the memory mapping
information from proc. But remove that is a different topic entirely.

drm: Kill file_priv->ioctl_count tracking

It's racy, and it's only used in debugfs. There are simpler ways to
know whether something is going on (like looking at dmesg with full
debugging enabled). And they're all much more useful.

So let's just rip this out.

10 years agodrm: rip out dev->ioctl_count tracking
Daniel Vetter [Wed, 11 Dec 2013 10:35:08 +0000 (11:35 +0100)]
drm: rip out dev->ioctl_count tracking

Now dev->ioctl_count tries to prevent the device from disappearing if
it's still in use. And if we'd actually need this code it would be
hopelessly racy and broken.

But luckily the vfs already takes care of this. So we can just rip it
out.
