8fd4bd2235 vt/console: try harder to print output when panicing
Jesse's initial patch commit said:

"At panic time (i.e.  when oops_in_progress is set) we should try a bit
harder to update the screen and make sure output gets to the VT, since
some drivers are capable of flipping back to it.

So make sure we try to unblank and update the display if called from a
panic context."

I've enhanced this to add a flag to the vc that console layer can set to
indicate they want this behaviour to occur.  This also adds support to
fbcon for that flag and adds an fb flag for drivers to indicate they want
to use the support.  It enables this for KMS drivers.

bf79cb914d drm: Use ENOENT consistently for the error return for an unmatched handle.
This is consistent with trying to access a filename that not exist
within a directory which is a good analogy here. The main reason for the
change is that it is easy to confuse the error code of EBADF as an
performing an ioctl on an invalid file descriptor (rather than an
unknown object).

0d18abedfa radeon: handle errors in radeon_hwmon_init()
Smatch complained that the ERR_PTR from hwmon_device_register() wasn't
handled.  I added some error handling in radeon_hwmon_init() to silence
the warning.

Unfortunately errors from radeon_pm_init() aren't handled so this
doesn't really make a difference beyond silencing the warning.

Also I changed DRM_ERROR() to dev_err() which is the new preferred
method.

one buses was used for more than one purpose.  This patch sets up
all i2c buses on the card in one place and users of the buses just

167ffc44ca drm: radeon: fix sign bug
The "error" variable is unsigned so it's never less than zero.  I
changed it to check if (freq < current_freq) directly.

"best_error" is also unsigned so "best_error - 100" could be a large
number instead of a negative.  Since "error" is unsigned it is never
less than a negative and so the cases where "best_error" is less than or
equal to 100 are false.

4c712e6c7e drm/radeon/kms: check/restore sanity before doing anything else with GPU.
On systems using kexec, the new kernel is booted straight from the old kernel, without any warning to the graphics driver. So the GPU is basically left as-is in a running state, however the CPU side is completly reset.

Without stating the saneness of anyone using kexec on live systems, we should at least try not to crash the GPU. This patch resets 3 registers to 0 that could cause bad things to happen to the running system.

This allows kexec to work on a Power6/RN50 system.

This is needed to enable audio support on devices using polling. In case user
decides to disable audio (module parameter) we still will try to use timer in
r600_audio_enable_polling. This would lead to BUG in kernel/timer.c.

42f14c4b45 drm/radeon/kms: fix shared ddc harder
This fixes a regression caused by b2ea4aa67b
due to the way shared ddc with multiple digital connectors was handled.

You generally have two cases where DDC lines are shared:
- HDMI + VGA
- HDMI + DVI-D

HDMI + VGA is easy to deal with because you can check the EDID for the
to see if the attached monitor is digital.  A shared DDC line with two
digital connectors is more complex.  You can't use the hdmi bits in the
EDID since they may not be there with DVI<->HDMI adapters.  In this case
all we can do is check the HPD pins to see which is connected as we have
no way of knowing using the EDID.

3f53eb6f84 DRM / radeon / KMS: Fix hibernation regression related to radeon PM (was: Re: [Regression, post-2.6.34] Hibernation broken on machines with radeon/KMS and r300)
There is a regression from 2.6.34 related to the recent radeon power
management changes, caused by attempting to cancel a delayed work
item that's never been scheduled.  However, the code as is has some
other issues potentially leading to visible problems.

First, the mutex around cancel_delayed_work() in radeon_pm_suspend()
doesn't really serve any purpose, because cancel_delayed_work() only
tries to delete the work's timer.  Moreover, it doesn't prevent the
work handler from running, so the handler can do some wrong things if
it wins the race and in that case it will rearm itself to do some
more wrong things going forward.  So, I think it's better to wait for
the handler to return in case it's already been queued up for
execution.  Also, it should be prevented from rearming itself in that
case.

Second, in radeon_set_pm_method() the cancel_delayed_work() is not
sufficient to prevent the work handler from running and queing up
itself for the next run (the failure scenario is that
cancel_delayed_work() returns 0, so the handler is run, it waits on
the mutex and then rearms itself after the mutex has been released),
so again the work handler should be prevented from rearming itself in
that case..

Finally, there's a potential deadlock in radeon_pm_fini(), because
cancel_delayed_work_sync() is called under rdev->pm.mutex, but the
work handler tries to acquire the same mutex (if it wins the race).

Fix the issues described above.

So when we added output polling, we'd suddenly use this code more often, and the fact that it always takes over crtc2 and messes with it during probing isn't what we really want to be happening. A more complete fix would to change it to use whatever crtc was free at the time, but for now lets stay simple and just don't poll if crtc2 is already in use.

Although a more correct fix was found I suspect we should do this as well, until we get a chance to readdres the tv out polling issues.

a081a9d6f5 drm/radeon/kms/r600+: use voltage from requested clock mode (v3)
This fixes FDO bug #28375, it's kind of regression, so quite important to have
it for .35.

V2: Fix on RV770+ as well. All other chipsets have only one clock mode per
state.

V3: I'm out of luck today. Grepped for voltage in r*.c and missed evergreen.

aa1df0f229 drm/radeon/kms/pm: Disable voltage adjust on RS780/RS880
The vddc value in the power tables is not an actual voltage
like on discrete r6xx/r7xx/evergreen systems, but instead has
a symbolic meaning (e.g., NONE, LOW, HIGH, etc.).  See atombios.h

Most RS780/RS880 vbioses don't have a SetVoltage table anyway,
so it shouldn't be doing anything to the hardware at the moment.

I need to figure out how voltage is supposed to work on the newer
IGPs; until then, disable it.

c9e75b2125 drm/radeon/kms/pm: add mid profile
This adds an additional profile, mid, to the pm profile
code which takes the place of the old low profile.  The default
behavior remains the same, e.g., auto profile now selects between
mid and high profiles based on power source, however, you can now
manually force the low profile which was previously only available
as a dpms off state.  Enabling the low profile when the displays
are on has been known to cause display corruption in some cases.

This is needed to enable accel in the ddx.  However,
due to a bug in older versions of the ddx, it relies
on accel being disabled in order to load properly on
evergreen chips.  To maintain compatility, we add a new
get accel param and call that from the ddx.  The old one
always returns false for evergreen cards.

9bad145ee2 drm/radeon: fix PM on non-vram cards.
PM attemps to unmap objects that aren't actually mapped into userspace ever,
so just don't bother unmapping them at this point, since all you are doing
is nothing. We should be making sure all access to these objects are locked in
kernel space instead. In theory the VRAM gart table is already done, and both
the shaders and stolen vga memory blocks are never accessed at runtime.

This patch is a combination of the previous two profile
patches, but without the index bugs.  It cleans up and
fixes some issues with pm profile setup on r6xx chips.
Some tables have different orderings for the power states,
also, r600 only has 1 clock mode per power state. On
desktop cards there are no battery modes, so the low and high
power states are the same.  For the low profile case, choose
the lower clock mode.

ce8f53709b drm/radeon/kms/pm: rework power management
- Separate dynpm and profile based power management methods.  You can select the pm method
  by echoing the selected method ("dynpm" or "profile") to power_method in sysfs.
- Expose basic 4 profile in profile method
  "default" - default clocks
  "auto" - select between low and high based on ac/dc state
  "low" - DC, low power mode
  "high" - AC, performance mode
  The current base profile is "default", but it should switched to "auto" once we've tested
  on more systems.  Switching the state is a matter of echoing the requested profile to
  power_profile in sysfs.  The lowest power states are selected automatically when dpms turns
  the monitors off in all states but default.
- Remove dynamic fence-based reclocking for the moment.  We can revisit this later once we
  have basic pm in.
- Move pm init/fini to modesetting path.  pm is tightly coupled with display state.  Make sure
  display side is initialized before pm.
- Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume.
- Remove dynpm module option.  It's now selectable via sysfs.

a424816fb3 drm/radeon/kms/pm: rework power management
Add two new sysfs attributes:
- dynpm
- power_state

Echoing 0/1 to dynpm disables/enables dynamic power management.
The driver scales the sclk dynamically based on the number of
queued fences.  dynpm only scales sclk dynamically in single head
mode.

Echoing x.y to power_state selects a static power state (x) and clock
mode (y).  This allows you to statically select a power state and clock
mode.  Selecting a static clock mode will disable dynpm.

Previous reset code leaded to computer hard lockup (need to unplug
the power too reboot the computer) on various configuration. This
patch change the reset code to avoid hard lockup. The GPU reset
is failing most of the time but at least user can log in remotely
or properly shutdown the computer.

Two issues were leading to hard lockup :
- Writting to the scratch register lead to hard lockup most likely
because the write back mecanism is in fuzy state after GPU lockup.
- Resetting the GPU memory controller and not reinitializing it
after leaded to hard lockup. We did only reinitialize in case of
successfull reset thus unsuccessfull reset quickly leaded to hard
lockup.

88b045077a drm/radeon: Fix sparc regression in r300_scratch()
Commit b4fe945405 ("drm/radeon: Fix
memory allocation failures in the preKMS command stream checking.")
added a regression in that it completely tossed the get_unaligned()
done by r300_scratch() which we added in commit
958a6f8ccb ("drm: radeon: Fix unaligned
access in r300_scratch().").

Put it back.

This patch is against the drm-fbdevfix1 branch. It removes the
drm_fb_helper_setcolreg function. The reason is that fb_setcolreg is only
used in the case where fb_setcmap is called and no fb_ops->fb_setcmap is
used. In the drm case we always need a fb_setcmap hook to handle multiple
crtcs so we don't need a fb_setcolreg hook. Please apply.

4abe35204a drm/kms/fb: use slow work mechanism for normal hotplug also.
a) slow work is always used now for any fbcon hotplug, as its not
   a fast task and is more suited to being ran under slow work.

b) attempt to not do any fbdev changes when X is running as we'll
   just mess it up. This hooks set_par to hopefully do the changes
   once X hands control to fbdev.

When we are running in a headless environment we have no idea what
output the user might plug in later, we only have hotplug detect
from the digital outputs. So if we detect no connected outputs at
initialisation, start a slow work operation to poll every 5 seconds
for an output.

this is only hooked up for radeon so far, on hw where we have full

386516744b drm/fb: fix fbdev object model + cleanup properly.
The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work.

This patch

a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs.
b) migrated all the fb helper functions out of the crtc helper file into the fb helper file.
c) pushed the fb probing/hotplug control into the driver
d) makes the surface sizes into a structure for ease of passing
This changes the intel/radeon/nouveau drivers to use the new helper.

90aca4d274 drm/radeon/kms: simplify & improve GPU reset V2
This simplify and improve GPU reset for R1XX-R6XX hw, it's
not 100% reliable here are result:
- R1XX/R2XX works bunch of time in a row, sometimes it
  seems it can work indifinitly
- R3XX/R3XX the most unreliable one, sometimes you will be
  able to reset few times, sometimes not even once
- R5XX more reliable than previous hw, seems to work most
  of the times but once in a while it fails for no obvious
  reasons (same status than previous reset just no same
  happy ending)
- R6XX/R7XX are lot more reliable with this patch, still
  it seems that it can fail after a bunch (reset every
  2sec for 3hour bring down the GPU & computer)

This have been tested on various hw, for some odd reasons
i wasn't able to lockup RS480/RS690 (while they use to
love locking up).

Note that on R1XX-R5XX the cursor will disapear after
lockup haven't checked why, switch to console and back
to X will restore cursor.

Next step is to record the bogus command that leaded to
the lockup.

V2 Fix r6xx resume path to avoid reinitializing blit
module, use the gpu_lockup boolean to avoid entering
inifinite waiting loop on fence while reiniting the GPU

225758d8ba drm/radeon/kms: fence cleanup + more reliable GPU lockup detection V4
This patch cleanup the fence code, it drops the timeout field of
fence as the time to complete each IB is unpredictable and shouldn't
be bound.

The fence cleanup lead to GPU lockup detection improvement, this
patch introduce a callback, allowing to do asic specific test for
lockup detection. In this patch the CP is use as a first indicator
of GPU lockup. If CP doesn't make progress during 1second we assume
we are facing a GPU lockup.

To avoid overhead of testing GPU lockup frequently due to fence
taking time to be signaled we query the lockup callback every
500msec. There is plenty code comment explaining the design & choise
inside the code.

This have been tested mostly on R3XX/R5XX hw, in normal running
destkop (compiz firefox, quake3 running) the lockup callback wasn't
call once (1 hour session). Also tested with forcing GPU lockup and
lockup was reported after the 1s CP activity timeout.

V2 switch to 500ms timeout so GPU lockup get call at least 2 times
   in less than 2sec.
V3 store last jiffies in fence struct so on ERESTART, EBUSY we keep
   track of how long we already wait for a given fence
V4 make sure we got up to date cp read pointer so we don't have
   false positive

5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

a5ee4eb754 PCI quirk: RS780/RS880: work around missing MSI initialization
AMD says in section 2.5.4 (GFX MSI Enable) of #43291 (AMD 780G Family
Register Programming Requirements):

  The SBIOS must enable internal graphics MSI capability in GCCFG by
  setting the following: NBCFG.NB_CNTL.STRAP_MSI_ENABLE='1'

Quite a few BIOS writers misinterpret this sentence and think that
enabling MSI is an optional feature.  However, clearing that bit just
prevents delivery of MSI messages but does not remove the MSI PCI
capabilities registers, and so leaves these devices unusable for any
driver that attempts to use MSI.

Setting that bit is not possible after the BIOS has locked down the
configuration registers, so we have to manually disable MSI for the
affected devices.

This fixes the codec communication errors in the HDA driver when
accessing the HDMI audio device, and allows us to get rid of the
overcautious quirk in radeon_irq_kms.c.

2b497502b7 drm/radeon: collect r100 asic related declarations in radeon_asic.h
This just an example to show what radeon_asic.h might be good for.
Before Jerome kills it ;)

In essence this creates a home for all asic specific declarations in
radeon_asic.h
