Subject: drm/radeon: properly handle mc_stop/mc_resume on evergreen+ (v2)

- Stop the displays from accessing the FB
- Block CPU access
- Turn off MC client access

This should fix issues some users have seen, especially
with UEFI, when changing the MC FB location that result
in hangs or display corruption.

v2: fix crtc enabled check noticed by Luca Tettamanti

Subject: drm/radeon/dynpm: wait for fences on all rings when reclocking

1. Drop gui idle stuff, it's not as reliable as fences and only
covers the 3D engine.
2. Wait for fences on all rings.  This makes sure all rings are
idle when reclocking.

Subject: drm/radeon: remove gui_idle interrupt infrastructure

It was only used for dynpm, but has been replaced with
a better implementation using fences.  Remove it.

From: Steven Fuerst <svfuerst@gmail.com>
Date: Wed, 15 Aug 2012 15:07:14 -0700
Subject: Rename i2f() to int2float(), and make it global so one copy can be
 removed.

Remove the copy of i2f() in r600_blit_kms.c
We rename the function to something longer now that it is a global
symbol.  This reduces the likelyhood of unintended clashes later.

This might be a candidate for inclusion inside general drm infrastructure.
However, at the moment only the radeon driver uses it.

Subject: Replace int2float() with an optimized version.

We use __fls() to find the most significant bit.  Using that, the
loop can be avoided.  A second trick is to use the behaviour of the
rotate instructions to expand the range of the unsigned int to float
conversion to the full 32 bits in a branchless way.

The routine is now exact up to 2^24.  Above that, we truncate which
is equivalent to rounding towards zero.

Subject: Annotate int2float() as being a pure function.

This allows gcc to fold duplicate calls into a single call.  Since
the current users do actually call it multiple times with the
same arguments, this is an obvious win.

Subject: drm/radeon: add new AMD ACPI header and update relevant code (v2)

Add a new header that defines the AMD ACPI interface used
for laptops, PowerXpress, and chipset specific functionality
and update the current code to use it.

Todo:
- properly verify the ACPI interfaces
- hook up and handle ACPI notifications
- make PX code more robust
- implement PCIe Gen and width switching using ACPI

v2: fix typo in header

Subject: drm/radeon: track whether the GPU controls the backlight (v2)

A table in the vbios tells us whether the GPU backlight controller
is used or not.  If the bit is set, the GPU backlight controller is
used; if it is not set, an off-chip backlight controller is used.

v2: store all the firmware flags, not just BL control

Subject: drm/radeon: refactor radeon_atif_call

Don't hard-code function number, this will allow to reuse the function.
v2: add support for the 2nd parameter (from Lee, Chun-Yi
<jlee@suse.com>).

Subject: drm/radeon: implement radeon_atif_verify_interface

Wrap the call to VERIFY_INTERFACE and add the parsing of the support
vectors.
v2: use a packed struct for handling the output of ACPI calls, hides
ugly pointer arithmetics (Lee, Chun-Yi <jlee@suse.com>).
v3: fix radeon_atif_parse_functions handling (Alex Deucher)

Subject: drm/radeon: implement handler for ACPI event
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Set up an handler for ACPI events and respond to brightness change
requests from the system BIOS.
v2: fix notification when using device-specific command codes
(tested by Pali Rohár <pali.rohar@gmail.com>); cache the encoder
controlling the backlight during the initialization to avoid searching
it every time (suggested by Alex Deucher).
v3: whitespace fixes (Alex Deucher).

Subject: ACPI video: allow events handlers to veto the keypress

The standard video events may be overloaded for device specific
purposes. For example AMD ACPI interface overloads
ACPI_VIDEO_NOTIFY_PROBE (0x81) to signal AMD-specific events. In such
cases we don't want to send the keypress (KEY_SWITCHVIDEOMODE) to the
userspace because the user did not press the mode switch key (the
spurious keypress confuses the DE which usually changes the
display configuration and messes up a dual-screen setup).
This patch gives the handlers the chance to examine the event and
block the keypress if the event is device specific.
v2: refactor as suggested by Zhang Rui <rui.zhang@intel.com>

The AMD ACPI interface may use ACPI_VIDEO_NOTIFY_PROBE to signal SBIOS
requests; block the keypress in this case since the user did not
actually press the mode switch key.

Store a reference to the VM into the IB structure, that
makes calculating the IBs address a bit less complicated.

Subject: drm/radeon: rework the VM code a bit more (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Roughly based on how nouveau is handling it. Instead of
adding the bo_va when the address is set add the bo_va
when the handle is opened, but set the address to zero
until userspace tells us where to place it.

This fixes another bunch of problems with glamor.

v2: agd5f: fix build after dropping patch 7/8.

Subject: drm/radeon: clean up encoder dp checks

Use the proper struct in the union.  That field
has the same offset in every struct, so no functional
change.

Subject: drm/radeon/atom: fix typo in SetPixelClock handling

MiscInfo field should be programmed with the crtc id
rather than the pll id.  However, at this point the
two are the same for chips with this version of the table.

Subject: drm/radeon: rework pll selection (v4)

For DP we can use the same PPLL for all active DP
encoders.  Take advantage of that to prevent cases
where we may end up sharing a PPLL between DP and
non-DP which won't work.  Also clean up the code
a bit.

v2: - fix missing pll_id assignment in crtc init
v3: - fix DP PPLL check
    - document functions
    - break in main encoder search loop after matching.
      no need to keep checking additional encoders.
v4: - same as v3, but re-apply to drm-next as the corner
      cases are fixed properly in subsequent patches.

fixes:

Subject: drm/radeon: allow PPLL sharing on non-DP displays

If several non-DP displays use the same pixel clock
we can use the same PPLL for all of them.  If all
relevant displays have the same pixel clock, this
allows the driver to:
- use fewer PPLLs which saves power
- support more than two non-DP displays on DCE4+

The current drm modesetting infrastructure doesn't
really provide a good framework for validating combinations
that work or won't work, so it's possible you could go from
a working configuration to a non-working one by changing the
mode a one of the displays.  However, there this is better
than what was there before.

Subject: drm/radeon: make non-DP PPLL sharing more robust

Compare the adjusted clock as well as the crtc mode
clock.  This handles cases where the driver adjusts
the clock for specific special cases.

From 57b35e29cf4e45eb163631c4ece10dbc259ddf30 Mon Sep 17 00:00:00 2001

Subject: drm/radeon: work around KMS modeset limitations in PLL allocation
 (v2)

Since the current KMS API sets the mode independantly on
each crtc, we may end up with resource conflicts.  The PLL
allocation is one of those cases.  In the following example
we have 3 crtcs in use driving 2 DVI connectors and 1 DP
connector.  On the initial kernel modeset for fbdev, the
display topology ends up as follows:

crtc0 -> DP-0
crtc1 -> DVI-0
crtc2 -> DVI-1

Because this is the first modeset, all of the PLLs are
available as none have been assigned.  So we end up with
the following:

crtc0 uses DCPLL
crtc1 uses PPLL2
crtc2 uses PPLL1

When X starts, it assigns a different topology:

crtc0 -> DVI-0
crtc1 -> DP-0
crtc2 -> DVI-1

However, since the KMS API is per crtc, we set the mode on each
crtc independantly.  When it comes time to set the mode on crtc0,
the topology for crtc1 and crtc2 are still intact.  crtc1 and
crtc2 are already assigned PPLL2 and PPLL1 so when it comes time
to set the mode on crtc0, crtc1 and crtc2 have not been torn down
yet, so there appears to be no PLLs available.  In reality, we
are reconfiguring the entire display topology, however, since
each crtc is handled independantly, we don't know that in the
driver at each crtc mode set time.

This patch checks to see if the same connector is being driven by
another crtc, and if so, uses the PLL already associated with it.

v2: store connector in the radeon crtc struct, simplify checking.

Subject: drm/radeon: restore backlight level on resume

Restore the backlight level on resume.  Some systems
need to explicitly restore the backlight level on
resume.

Fixes panel resume on my Trinity laptop and may fix the
following bugs:
https://bugs.freedesktop.org/show_bug.cgi?id=43829
https://bugzilla.kernel.org/show_bug.cgi?id=46241

Subject: drm/radeon: refactor set_page chipset interface v5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cleanup the interface in preparation for hierarchical page tables.

v2: add incr parameter to set_page for simple scattered PTs uptates
    added PDE-specific flags to r600_flags and radeon_drm.h
    removed superfluous value masking with 0xffffffff

v3: removed superfluous bo_va->valid checking
    changed R600_PTE_VALID to R600_ENTRY_VALID to handle PDE too

v4 (ck): fix indention style, rework and fix typos in commit message,
         add documentation for incr parameter, also use incr
         parameter for system pages

v5 (agd5f): use upper_32_bits() and minor white space fixes

From fa87e62d357ccf73831cd52ed316593d0968020d Mon Sep 17 00:00:00 2001
From: Dmitry Cherkasov <dcherkassov@gmail.com>

Subject: drm/radeon: add 2-level VM pagetables support v9
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PDE/PTE update code uses CP ring for memory writes.
All page table entries are preallocated for now in alloc_pt().

It is made as whole because it's hard to divide it to several patches
that compile and doesn't break anything being applied separately.

Tested on cayman card.

v2: rebased on top of "refactor set_page chipset interface v3",
    code cleanups

v3: switched offsets calc macros to inline funcs where possible,
    remove pd_addr from radeon_vm, switched RADEON_BLOCK_SIZE define,
    to 9 (and PTE_COUNT to 1 << BLOCK_SIZE)

v4 (ck): move "incr" documentation to previous patch, cleanup and
         document RADEON_VM_* constants, change commit message to
         our usual format, simplify patch allot by removing
         everything current not necessary, disable SI workaround.

v5: (agd5f): Fix typo in tables_size calculation in
             radeon_vm_alloc_pt().  Second line should have been
             '+=' rather than '='.

v6: fix npdes calculation. In scenario when pfns to be mapped overlap
two PDE spans:

   +-----------+-------------+
   | PDE span  | PDE span    |
   +-----------+----+--------+
          |         |
          +---------+
          | pfns    |
          +---------+

the following npdes calculation gives incorrect result:

npdes = (nptes >> RADEON_VM_BLOCK_SIZE) + 1;

For the case above picture it should give npdes = 2, but gives one.

This patch corrects it by rounding last pfn up to 512 border,
first - down to 512 border and then subtracting and dividing by 512.

v7: Make npde calculation clearer, fix ndw calculation.

v8: (agd5f): reserve enough for 2 full VM PTs, add some
             additional comments.

v9: fix typo in npde calculation

Subject: drm/radeon: allow MIP_ADDRESS=0 for MSAA textures on Evergreen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MIP_ADDRESS should point to the resolved FMASK for an MSAA texture.
Setting MIP_ADDRESS to 0 means the FMASK pointer is invalid (the GPU
won't read the memory then).

The userspace has to set MIP_ADDRESS to 0 and *not* emit any relocation
for it.

Subject: drm/radeon: rework the vm_flush interface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pass the vm and ring index rather than an IB.  This allows
us to use the vm_flush interface for non-IB cases in the
future.
