radeon_hd: auxPin zero is valid, check also on eDP type

EDID is correctly read. It can then be passed to the app_server.
At least the app_server tries to set the native resolution.

It doesn't really help to get further, because the ATOMBios code can't handle newer
table versions (for instance 3.2).

accelerant/radeon_hd: Add missing newline to error message

Change-Id: Ic145f75ae8a05f901e6202fbb552260f7f74efe0

accelerant/radeon_hd: Allow failure to init card

* Previously, any accelerants failing would cause an
app_server crash.. so we would do everything in our
power to get "something"
* After hrev56252, the app_server properly handles
accelerant failures and vesa / framebuffer accelerants
should will be used.
* Thus, if no monitors were detected (due to none being
plugged-in, or some other fault), bail and return B_ERROR
so vesa fallback can give it a try.

RadeonHD: Bit-bang LVDS for edid

* Older cards have to use the LVDS_Info table,
newer cards also have an ddc pin for EDID.
* Some buggy sbios don't inject the EDID into
the vbios as they should
* This corrects hrev45812 as we need to still
call connector_read_mode_lvds to obtain the
spread spectrum data for the lvds.
* Call connector_read_mode_lvds, bit-bang the
connector, choose the best outcome.

RadeonHD: Prefer edid over LVDS_Info

* Some oem sbios implementations are buggy
and don't overwrite the LVDS panel info over
LVDS_Info in vbios as they should.
* Bit-bang EDID info from LVDS connector before
falling back to the LVDS_Info table.
* Partially fixes #8457

radeon_hd: Fix DVI-I detection once and for all

* Reduced the logic down and only use it where
possible.
* Remove the duplicate gpio pin check. While this

right while detecting displays vs relying on
connector order in the ASIC. This gpio pin check
was also severely bugged (missing {}'s)
* Should fix #8913 and maybe others

radeon_hd: Fix DisplayPort link training

* Original changes by Bill Randle
* Includes a large number of modifications
and cleanups.
* Add a "currentMode" to the gDisplay to

bit, adding a "currentMode" allows code
to know the intended display mode being set
without passing the mode pointer around as
much)

radeon_hd: Improve displayport support

* Modified patch submitted by Bill Randle.
* DisplayPort aux communications now working.
* DP Link Training still not functioning properly.

radeon_hd: Fix missing TRACE connector id

radeon_hd: Improve pitch width alignment

radeon_hd: Rework PLL picking code

* Rewrote to be more efficient and more accurate.
* Fix a DP bug where we didn't choose the correct
external PLL.

radeon_hd: clean up clock units

* Ensure we store all clock units as khz or
n * 10 off from AtomBIOS unit expected
* Perform DDC setup of external encoder

radeon_hd: crtc_memreq only on DCE 3 - 5

* Prevent some atombios missing table errors
on DCE 6 and later

radeon_hd: Style fix, no functional change

radeon_hd: Style cleanup of display.cpp

* These errors slipped in from an external patch
* No functional change

RadeonHD: Bit-bang LVDS for edid

* Older cards have to use the LVDS_Info table,
newer cards also have an ddc pin for EDID.
* Some buggy sbios don't inject the EDID into
the vbios as they should
* This corrects hrev45812 as we need to still
call connector_read_mode_lvds to obtain the
spread spectrum data for the lvds.
* Call connector_read_mode_lvds, bit-bang the
connector, choose the best outcome.

RadeonHD: Prefer edid over LVDS_Info

* Some oem sbios implementations are buggy
and don't overwrite the LVDS panel info over
LVDS_Info in vbios as they should.
* Bit-bang EDID info from LVDS connector before
falling back to the LVDS_Info table.
* Partially fixes #8457

radeon_hd: Fix DVI-I detection once and for all

* Reduced the logic down and only use it where
possible.
* Remove the duplicate gpio pin check. While this
is a determining factor... i'd rather get it
right while detecting displays vs relying on
connector order in the ASIC. This gpio pin check
was also severely bugged (missing {}'s)
* Should fix #8913 and maybe others

radeon_hd: Fix DisplayPort link training

* Original changes by Bill Randle
* Includes a large number of modifications
and cleanups.
* Add a "currentMode" to the gDisplay to
enable easier checking of intended changes.
(we pass the display_mode around quite a
bit, adding a "currentMode" allows code
to know the intended display mode being set
without passing the mode pointer around as
much)

radeon_hd: Improve displayport support

* Modified patch submitted by Bill Randle.
* DisplayPort aux communications now working.
* DP Link Training still not functioning properly.
* The DP edid data isn't used yet as we still use
the vesa edid during the mode setting.

radeon_hd: Become Spread Spectrum aware

* Enable Spread Spectrum when requested
* Tested working across several cards, does
have regression potential though.

radeon_hd: cleanup some logic; no functional change

radeon_hd: re-rework some pll code

* Grab pseudo pll SS info for early
Spread Spectrum access
* display_crtc_ss now takes a pll vs
a display for easy pll access

radeon_hd: rework some pll code

* Force fractional feedback divider on APU's
* Spread Spectrum is now probed more correctly
across multiple encoders and cards
* SS still disabled however.

radeon_hd: r5xx to Avivo define cleanup

* Reorganize and clean up card defines
* Fix define spaces
* Unify card naming
* No (real) functional change

radeon_hd: Card define cleanup

* Trying to do cleanup on the layout of these headers

radeon_hd: Skip 9DIN connector.

* Since we really don't support multiple
heads well, skip 9DIN for the moment as
it is a luxury.

radeon_hd: Build fix

* Misplaced '"', sorry for spam

radeon_hd: Better handle and detect load on DVI-I connectors

* A tricky situation as DVI-I digital + analog paths show
up as two display connectors sharing one EDID data source.

radeon_hd: display_info struct style cleanup

* No functional change

radeon_hd: Make crtc lookup fault less catastrophic

radeon_hd: Fix digital output

* Resolves blocker #8322.
* Should resolve #8151, #8163, #8282, #8457
* Digital output on DVII was getting hard set
in the encoder to analog / CRT mode.
* We now check the edid "type" flag
* Flag gets set to 1 if edid data from digital
transmitter, 0 if analog transmitter.

radeon_hd: Fix bytes per row passed to app_server

* Video modes with widths that are not multiples of
32 were failing to set
* Should solve analog "skewed display"
* Add debugging on adjusted framebuffer pitch
* Thanks go out to AMD open source developers for
the help tracking this one down!

radeon_hd: Correct framebuffer pixel pitch alignment

radeon_hd: Add spread spectrum control functions

* Store SS information with PLL
* Probe SS information for PLL
* Disable SS more correctly
* May resolve mode setting issues on newer cards

radeon_hd: DisplayPort encoder fixes.

* Handle external encoder case properly when
pulling encoder mode.
* Return DisplayPort encoder if DisplayPort
connector.
* Handle DVO properly when pulling encoder mode

radeon_hd: Fix bugs in external DP bridge code

* non-external encoder will never be a DP bridge.
* use external encoder in places where needed.
* ensure we look at proper encoder for isDPBridge.

Revert "radeon_hd: Convert encoders to pointers"

This reverts commit 5a1f9f0f16b2a4bef89b61b4e3e24bf0b53917da.

* Thinking on this a bit more, this is really a silly change as
I know the upper limit for number of valid encoders.
* Resolves a app_server crash introduced as well due to not
allocating encoder pointer.

radeon_hd: Convert encoders to pointers

* Preparation for multiple encoders per connector

radeon_hd: Whitespace cleanup, no functional change

radeon_hd: Begin improvement on crtc state control

* Try to not blank the crtc when it is alreay disabled
* Clean up wording, active now present on display info
* Don't lock crtc when doing normal dpms calls, crtc
should only be locked during mode set / change

radeon_hd: Implement preferred mode

* Add preferredMode display mode to each display.
* If LVDS is detected, set preferredMode based on AtomBIOS
* Fixes blocker #8329 ?

DisplayPort call organization and cleanup

* Add color space to BPP function
* Pass display_mode to DP lane count function
* Get BPP in DP lane count
* Move some DPInfo population out of DP link training
as other things need them sooner.
* Fill out DP code in external encoder setup

Improve debugging

* Provide more information on connectors
* Provide more information on detected attributes
* Remove some no longer needed debug output
* Provide connector ID on display debug output

Style cleanup, space after switch as it is not a function

Pointer style cleanup; Variable consolidation

Include file style cleanup, no functional change

Move connector code into new connector source file.

* clean up some comments
* most of this movement is prep for AUX display transactions

Create connector source file, move connector bus calls into it

* this will help break apart some of the sources
* display bus communications really don't belong with GPU operations
* rename functions to better describe their actions

Add lookup of encoder id -> name for debugging

Improve pll calculations dealing with DisplayPort devices

* rename encoder_isexternal to encoder_is_external
* add encoder_is_dp_bridge call for special DP cases
* add initial get_dp_link_clock, hard code a guess for now
* take external DP encoders into consideration when making
pixel clock adjustments

Improve legacy card support and cleanup

* break apart encoder type lookup to share with legacy
connector probe
* add function to check for external encoders
* reduce chip requirement to Avivo+ from R600 for register population

Add legacy card connectior detection using table method
* attempt AtomBIOS table probe first, then fallback to legacy method if
no connectors found (or table version is too old)
* add function to look up object info on older cards
* dcc still needs some work on old cards
* my X1200 IGP gets video now

* style cleanup of shared storage names
* return better data on card
* display chipset flags in screen preflet


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@43226 a95241bf-73f2-0310-859d-f6bbb57e9c96

* add lots of missing evergreen defines

more closely match drm driver as the chipset
model numbers aren't in order and change from
numbers to names.
* check for evergreen when populating frame buffer
information.
* style cleanup


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@43225 a95241bf-73f2-0310-859d-f6bbb57e9c96

* change the way we store GPU MC state information
on halt / resume as it doesn't need to persist.
* rename mc_info -> fb_info to better communicate
it's contents
* add some gart (gtt) storage and prep AGP VM code


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@43212 a95241bf-73f2-0310-859d-f6bbb57e9c96

* reorganize register definitions
There were a large number if incorrect, duplicated, misplaced
registers that were leading to bugs in the code. This is my first
shot at cleaning them up. Luckly as we are using AtomBIOS the number
of registers we need to know about is shrinking.
* remove registers left over from register banging days
* r770 is less then r710, r720 in the drm sources. Fix in code.
* enable newer radeons for testing


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42930 a95241bf-73f2-0310-859d-f6bbb57e9c96

* redesign pretty much everything frame buffer related
* don't resize the frame buffer after mapping it.. doesn't make sense
* add memory controller code and program the memory controller for r600
* remove unneeded frame_buffer_int
* don't malloc mc_info, waste of time
* fix scaler setting
* vramStart in mc should be 0... get vertical colored lines however when this
this is set properly (everything in mc_info is the MC view of FB BAR)
When vramStart is the FB physical address... i get proper video on some cards
... thoughts?

* map all i2c gpio pins on accelerant init
* use a smaller sub function to attach gpio info to connector i2c info


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42773 a95241bf-73f2-0310-859d-f6bbb57e9c96

* fix header function define
* while doing our last-resort fallback, skip
TV DAC encoders as it is likely that is not

as the driver matures. (ex: only a tv is
connected, no edid)

as a last resort... SimNow seems to be ok with this and
I get a valid screen mode set :)

it's needed using the gpio information
* rename gpio information struct to be cleaner and shorter
* add function to debug found connectors

to working ddc / edid per connector
* change gpio_info u16's to u32's to ensure we aren't overflowing anything
* fix bug always setting hw_capable true
* change TRACE to ERROR to always show debug data when called

* reformulate display and connector storage to match AtomBIOS requirements
* each active gDisplay references a gConnector index
