Have almost integrated the new CCD, AMD and NVIDIA
libraries into DIsplayMagician. The CCD library is working
fine. The AMD library is partially completed, but is awaiting
some help from AMD, as it appears one of their driver functions
is broken (or at least incorrectly documented). The NVIDIA
library is currently still under development, but I've still copied
it across so that I could work on the additional profile objects
that need to be prepared in order for this to work.
As I am waiting on a response from AMD, the plan is now that
I will swap over to an NVIDIA based video card in my test machines
and I will start work on the NVIDIA library. The NVIDIA library seems
straight forward compared to AMD, so that hopefully won't take too
long to do. Once that library is compete, I'll test it within NVIDIAInfo
application until its working, and then I'll port it back over to
DisplayMagician. That will then let me complete the last bits of the
integration so that I can complete the last of the NVIDIA tests.
Hopefully by the time all this happens I will have heard back from
AMD and I will be able to continue work with that section of code.
Added some basic CCD library functionality
to be able to set Windows displays directly
from the code. This will enable future native
HDR support through windows, as well as
allow positioning and screen setup to work
better through here than via the AMD driver.
Will still need to work on AMD Eyefinity support
once this is completed.
Now have the DisplayProfile storing the minimal set of
data that it needs. It also recreates the Screens list (used
for creating profile bitmaps and icons) and recreates the
DisplayProfileBitmaps each time at present. I will add some
logic to deerialise the bitmaps again at a later date once
I've compeleted actually applying the AMD display confs.
Now works with single screens and similar
so that they show correctly on the page without
being hidden by foreground stuff. Still might
make the DisplayView larger if it makes sense.
Have managed to get a working displayview
for AMD (not working in spanned mode) and
currently playing with the colours and layout.
Once I have something locked in, I'll troubleshoot
the ProfileDisplay file writing.
Trying to figure out a video card agnostic way
of generating the display icons fo both standard
and spanned displays. Still trying to figure out
exactly which AMD ADL calls I need to make to
get all the information I need. It is NOT very well
documented. It's actually really annoying! AMD
need to do better.
Trying to make the DisplayView and ProfileIcon
image drawing logic more generic so that it will
work with NVIDIA, AMD , Intel and Windows video
card drivers. Having to reverse engineer the amazing
wok that Soroush did with this stuff. I just know that
I'm going to break this before I fix it, but I really think
this is needed in order for this new video card
separation refactoring to work. This is going to take a
while I feel!
This is part of the new strategy to split the
ProfileItems into different derived clases with
one per Video card technology. The purpose is
to allow each video card driver to produce a
slightly different profiledata section which is
customised to the needs of that video card.
This will allieviate the need for us to extend
the Path object to support AMD, as we'll be
doing the differentiation at each ProfileItem.
Time will tell if this is a better strategy or not.
This is all to do with my even longer term
strategy of devloping video card driver library
files inhouse. This strategy was directly created
just so that I can make changes in my own code
if I need to support some additional features
such as HDR support within the profiles. It is very
difficult to do this if I'm using another video card
library. Much more simple to update my own code!
Moving to a situation where each library has
it's own ProfileData structure which will require
me to break the existing Profile structure.
This will be better once finished, but it could
be a month before I get this rewrite finished :/
Decided that the DisplayProfile changes would
have to be breaking changes if I was going to
add HDR support, and be able to handle adding
future video cards from different manufacturers.
This all requires a change to the DisplayProfile
format. So now this is going to use a file called
DisplayProfiles_2.0.json rather than a file called
DisplayProfiles_1.0.json. This is because the
profiles will need to be generated again from
scratch, as they will all be completely different
to the format in DisplayProfiles_1.0.json.
We have to do this as we will be moving
to a new video card library-based way of
getting the Display Profiles information.
This is designed to enable me to add new
video card drivers in the future, such as
Intel, in order to support 'combined'
video screens,
I finally figured out how to check for displays
that are selectable, but aren't in use. It's not
as striaght forward with AMD ASL library as
it is with NVIDIA's driver, thats for sure.
Seem to have fixed the exceptions based on
all the testing I've been doing. So there is at
least that!
Have now go the required data, but for some
reason AMD is returning two valid adapters
when there is actually just one in the system!
Could be a problem with the device installation,
but I will need figuring out how to either remove
duplicates, or figure out the information to use as
a filter for ignoring one of the adapters.
We now have enough data for me to identify
all the connected display devices, and to
generate a display identifier which will work
no matter if AMD Eyefinity is enabled or not!
This should allow me to generate an display
identifier that will work like the NVIDIA ones.
Trying different ways to get a list of all the connnected
displays via the AMD ADL library. It seems pretty
onerous at the moment, and seems like there is still a
lot of work to go :/. AGS may have been the better
way to go, but ADL at least had a C# example for me
to start with!
Need to add Display Device info extraction.
Have created consts for the connector types
in c#, but now need to add the logic to decode
the ADLDeviceConfig returned value!
This is a lot of learning about Pinvoke
and the way to marshal c structures
into c# managed structures when passed
as out.
This is all a lot more indepth than I was
hoping it was going to be!
There is a long road ahead of me, but
at least some of the structure is working
now! We can at least call the AMD ADL
library and get results returned back!
