Register 0x42020 was defined twice under the names PCH_DSPCLK_GATE_D and
ILK_DSPCLK_GATE. This patch consolidate the 2 sets of defines in one.
The transforms done are:
PCH_DSPCLK_GATE_D -> ILK_DSPCLK_GATE_D
ILK_DSPCLK_GATE -> ILK_DSPCLK_GATE_D
DPARBUNIT_CLOCK_GATE_DISABLE -> ILK_DPARBUNIT_CLOCK_GATE_DISABLE
ILK_DPARB_CLK_GATE -> ILK_DPARBUNIT_CLOCK_GATE_DISABLE
DPFDUNIT_CLOCK_GATE_DISABLE -> ILK_DPFDUNIT_CLOCK_GATE_DISABLE
ILK_DPFD_CLK_GATE -> ILK_DPFDUNIT_CLOCK_GATE_DISABLE
ILK_CLK_FBC -> ILK_DPFDUNIT_CLOCK_GATE_DISABLE
DPFCRUNIT_CLOCK_GATE_DISABLE -> ILK_DPFCRUNIT_CLOCK_GATE_DISABLE
ILK_DPFC_DIS1 -> ILK_DPFCRUNIT_CLOCK_GATE_DISABLE
DPFCUNIT_CLOCK_GATE_DISABLE -> ILK_DPFCUNIT_CLOCK_GATE_DISABLE
ILK_DPFC_DIS2 -> ILK_DPFCUNIT_CLOCK_GATE_DISABLE
We have a VHRUNIT_CLOCK_GATE_DISABLE define for the pre-ILK DSPCLK_GATE_D.
Even if the same bit is used in ILK_DSPCLK_GATE_D, other bits in the
register change, so I went with re-defining it, well more precisely rename
IVB_VRHUNIT_CLK_GATE, which is not specific to IVB+. So:
IVB_VRHUNIT_CLK_GATE -> ILK_VHRUNIT_CLOCK_GATE_DISABLE
VHRUNIT_CLOCK_GATE_DISABLE -> ILK_VHRUNIT_CLOCK_GATE_DISABLE (ILK+ code)
This commit is only a renaming commit, further commits will clean up the
logic.
v2: Rename bit 5 and 7 to _ENABLE as setting them to 1 enables clock

With the introduction of per-process GTT space, the hardware designers
thought it wise to also limit the ability to write to MMIO space to only
a "secure" batch buffer. The ability to rewrite registers is the only
way to program the hardware to perform certain operations like scanline
waits (required for tear-free windowed updates). So we either have a
choice of adding an interface to perform those synchronized updates
inside the kernel, or we permit certain processes the ability to write
to the "safe" registers from within its command stream. This patch
exposes the ability to submit a SECURE batch buffer to
DRM_ROOT_ONLY|DRM_MASTER processes.

radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[]
to destroy each of them.
radeon_ext_tmds_enc_destroy() however also has code to destroy it's
associated I2C bus rec which has been obtained by radeon_i2c_lookup()
and is therefore also in the i2c_bus[] list.
This causes a double free resulting in a kernel panic when unloading
the radeon driver.
Removing destroy code from radeon_ext_tmds_enc_destroy() fixes this
problem.

causing the regression.
Furthermore resume has been constantly switching between working and

seemingly with no related change as a root cause. And always with the
same symptoms of the backlight lighting up, but the lvds panel only
displaying black.
Also, of both i855gm variants only one is in the table. And in the
past we've only ever removed entries from this quirk table because it
breaks things.

You may notice that DDI_BUF_CTL is enabled in .enable but disabled in
.post_disable instead of .disable. Yes, the mode set sequence is not
exactly symmetrical, but let's assume the spec is correct unless we
can prove it's wrong.

Introduced in commit 87f8020ec9:
drm/i915: implement WaDisableEarlyCull for VLV and IVB
Notice that the original patch sent to the mailing list did not
include the Haswell chunk, it was added later.
The bit set by the commit does not exist on Haswell machines (at least
that's what the documentation says). Also, the commit gives me a GPU
hang every time we're loading the driver. So let's revert the Haswell
chunk, making the patch do only what its title actually says.

Just set the only bit we need, everything else is either ignored on
HDMI or should be set to zero.
Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com>
Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
Problems with the previous code:
- HDMI just uses WRPLL1 for everything, so dual head cases might not
work sometimes.
- At encoder->mode_set we just write the PLL register without doing
any kind of check (e.g., check if the PLL is already being used).
- There is no way to fail and return error codes at
encoder->mode_set.
- We write to PORT_CLK_SEL at mode_set and we never disable it.
- Machines hang due to wrong clock enable/disable sequence.
So here we rewrite the code, making it a little more like the
pre-Haswell PLL mode set code:
- Check PLL availability at ironlake_crtc_mode_set.
- Try to use both WRPLLs.
- Check if PLLs are used before actually trying to use them, and
properly fail with error messages.
- Enable/disable PORT_CLK_SEL at the right place.
- Add some WARNs to check for bugs.
The next improvement will be to try to reuse PLLs if the timings
match, but this is content for another patch and it's already
documented with a TODO comment.

Right now, we're trying to enable LCPLL at every mode set, but we're
never disabling it. Also, we really don't want to be disabling LCPLL
since it requires a very complex disable/enable sequence. This
register should really be set by the BIOS and we shouldn't be touching
it. Still, let's try to check its value and print some errors in case
we find something wrong. We're also adding intel_ddi_get_cdclk_freq
which will be used later in other places.

A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
currently it lost original meaning but still has some effects:
| effect | alternative flags
-+------------------------+---------------------------------------------
1| account as reserved_vm | VM_IO
2| skip in core dump | VM_IO, VM_DONTDUMP
3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
This patch removes reserved_vm counter from mm_struct. Seems like nobody
cares about it, it does not exported into userspace directly, it only
reduces total_vm showed in proc.
Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.
remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

I've discovered this on my ivb machine while stress-testing the new

Note that this is empirical duct-tape: I've noticed that we seem to
only ever miss the very first vblank irq right after enabling the
pipe. And with this hack applied I couldn't reproduce the failure case
anywhere else any more.

By using round_jiffies() we can align the wakeup of our worker to the
nearest second in order to batch wakeups and reduce system load, which
is useful for unimportant coarse tasks like our retire_requests.
v2: round_jiffies_relative() already returns the relative timeout value,
so no need to incorrectly perform the subtraction twice. The timer
interface still leaves the possibility for the value of jiffies to
change be we program the timer.

Quoting Chris :
"That BUG_ON there is silly and can simply be removed. The check is to
verify that no batches were submitted to the kernel whilst the UMS/GEM
client was suspended - to which the BUG_ONs are a crude approximation.
Furthermore, the checks are too late, since it means we attempted to
program the hardware whilst it was in an invalid state, the BUG_ONs are

There's is another register (a read only, so no harm done) at 0x42020 on
Haswell GPUs. Let's just remove the write from the copy&paste that
introduced haswell_init_clock_gating().
A note for the interested reader, it does seem we have a duplication of
the 0x42020 register definition, hence the removal of 2 writes. That
duplication could be the object of a later patch.

exynos-drm-hdmi need context pointers from hdmi and mixer. These
pointers were expected from the plf data. Cleaned this dependency
by exporting i/f which are called by hdmi, mixer driver probes

Pull drm merge (part 1) from Dave Airlie:
"So first of all my tree and uapi stuff has a conflict mess, its my
fault as the nouveau stuff didn't hit -next as were trying to rebase
regressions out of it before we merged.
Highlights:
- SH mobile modesetting driver and associated helpers
- some DRM core documentation
- i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
combined pte writing, ilk rc6 support,
- nouveau: major driver rework into a hw core driver, makes features
like SLI a lot saner to implement,
- psb: add eDP/DP support for Cedarview
- radeon: 2 layer page tables, async VM pte updates, better PLL
selection for > 2 screens, better ACPI interactions
The rest is general grab bag of fixes.
So why part 1? well I have the exynos pull req which came in a bit
late but was waiting for me to do something they shouldn't have and it
looks fairly safe, and David Howells has some more header cleanups
he'd like me to pull, that seem like a good idea, but I'd like to get
this merge out of the way so -next dosen't get blocked."
Tons of conflicts mostly due to silly include line changes, but mostly

Pull preparatory patches for user API disintegration from David Howells:
"The patches herein prepare for the extraction of the Userspace API
bits from the various header files named in the Kbuild files.
New subdirectories are created under either include/uapi/ or
arch/x/include/uapi/ that correspond to the subdirectory containing
that file under include/ or arch/x/include/.
The new subdirs under the uapi/ directory are populated with Kbuild
files that mostly do nothing at this time. Further patches will
disintegrate the headers in each original directory and fill in the
Kbuild files as they do it.
These patches also:
(1) fix up #inclusions of "foo.h" rather than <foo.h>.
(2) Remove some redundant #includes from the DRM code.
(3) Make the kernel build infrastructure handle Kbuild files both in
the old places and the new UAPI place that both specify headers
to be exported.
(4) Fix some kernel tools that #include kernel headers during their
build.
I have compile tested this with allyesconfig against x86_64,
allmodconfig against i386 and a scattering of additional defconfigs of
other arches. Prepared for main script

For now, only 2 control modes are available:
- NONE: The fan is never touched (default)
- MANUAL: The fan is set to the user-defined fan speed (pwm1)
This patch introduces a distinction between ptherm internal fan management
and external fan management. The latter is bound to respect the fan mode
while the first can still select the speed it wants unless the NONE mode

The previous driver waited for 250ms to accumulate data. This version times a
complete fan rotation and extrapolates to RPM.
The fan rotational speed should now be read in less than 250ms (worst case)
and usually in less 50ms.

It looks scary because of the size, but I tried to keep the differences minimal.
Further patches will fix the actual "driver" code and add new features.
v2: change filenames, split to submodules
v3: add a missing include
v4: Ben Skeggs <bskeggs@redhat.com>
- fixed set_defaults() to allow min_duty < 30 (thermal table will
override this if it's actually necessary)
- fixed set_defaults() to not provide pwm_freq so nv4x (which only has
pwm_div) can actually work. the boards using pwm_freq will have a
thermal table entry to provide us the value.
- removed unused files

If nouveau_pm_perflvl_get() fails, pm->profiles list will be left
uninitialized, which causes oops during nouveau_pm_fini().
Move INIT_LIST_HEAD before call to nouveau_pm_perflvl_get().

Not really sure how to confirm this 100%, but, the numbers match on all the
traces I have for NVCx (2 LTS), NVD9 (1LTS) and NVEx (4LTS).

Triggers PIBUS interrupts due to register not existing anymore, and as
a result HUB_SET_CHAN times out.
After this commit, our fuc loads and can accelerate at least fbcon, X,
glxgears and OA on NVE4. NVE7 not tested as of yet.

Currently identical except the available chipset register lists. This will
*not* currently work and is disabled by default because of this.
May get merged again later, remains to be seen what further changes will be
required.

Future code will use the object class rather than chipset checks in order to
identify available channel features.

This value will match something that's easily available from the engine IRQ
handlers, and used to lookup the relevant context.
Since the changes in how this is done on each generation match when the
major PFIFO changes happened, fifo is responsible for calculating the
correct value to avoid duplicating the same code among many engine modules.

Kepler PFIFO lost the ability to address multiple engines from a single
channel, so we need a separate one for the copy engine.

This is a HUGE commit, but it's not nearly as bad as it looks - any problems
can be isolated to a particular chipset and engine combination. It was
simply too difficult to port each one at a time, the compat layers are
*already* ridiculous.
Most of the changes here are simply to the glue, the process for each of the
engine modules was to start with a standard skeleton and copy+paste the old
code into the appropriate places, fixing up variable names etc as needed.

This is all very much a policy thing, and hence will not belong in SW
after the rework.
engsw now only handles receiving the event to say "can flip now" and makes
a callback to perform the actual work.
