AMDGPU DC Display Code Ported To GCN 1.0 "Southern Islands" GPUs

Last thing I know it was pending new firmware release from AMD.

the real issue is someone has to write it first and they are busy

Dave was one of the guys who sided with ATI to counter the real open source driver written by SuSE for AMD (ATIs new owner which was working hard to try to get ATI under control and to clean up the big mess that was there) and Dave only started development close to 5 months after the development of the real driver had started, and 2 months after the real driver was made public. Dave did more to keep the fglrx ways going than he helped progress either technically or with respect to open source affinity.

Seriously you appear with your RadeonHD checklist in almost every topic I can remember. What the point?

Like if kernel maintainers choose RadeonHD way instead of what AMD managenent was pushing for grass would be greener now. It's made sense to argue about it like 5 years ago since from your standpoint time were wasted for creating inferior driver, but today when we actually have functioning and almost fully featured one. Yeah it's could be more open, but AMD didn't wanted it for whatever reason so it's wouldn't work.

Everyone who used Linux learned hard way that community even with RH backing can't make GPU drivers without a lot of effort from vendor. Otherwise there will be more effort towards Nouveau and there is very little regardless of marketshare.

I'm assuming he's just annoyed when someone doesn't portrait bridgman and airlied as antiheroes. What he's talking about is happenings around eight years ago. There's a lot of newer happenings since then that he disregards. Heck, back at that time OpenGL 3.3 support seemed like a pipe dream and open drivers were playing hopeless catchup game against proprietary drivers

Edit: engineers and managers aren't antiheroes but they aren't heroes either. Everyone occasionally makes bad judgement calls

This is what I was referring to, and it seems they were going to do it:

There are some mammoth skeletons in the closets of Dave Airlie and John Bridgman and a few others. People should not glorify them, especially not for things they did not do or never did positively influence.

i have a hawai r9 290, very capable card not that much slower than an rx 570. But i too have to manually enable amdgpu.

For VGA connectors SI and CI can't use DC, so can't enable amdgpu.dc=1 still

HAWAII doesn't support VGA anyway. I don't know why DC is not already enabled for that chip.

Or some amdgpu.dc=auto which automatically decides whether to use DC or not, depending on whether VGA outputs exist.

That's because those cards are hardware incompatible with FP64. So, I'm not sure what else you can be asking for.

The proprietary fglrx driver had implemented FP64 emulation, plus there was some work done for mesa in the past.

DC is enabled by default for hawaii.

Or some amdgpu.dc=auto which automatically decides whether to use DC or not, depending on whether VGA outputs exist.

This is already the default behavior. DC is only enabled by default on asics that are fully supported. You can set dc=0 or dc=1 to override the default behavior (-1).

Does that mean all that's missing now is the video acceleration stuff for SI? Someone outwith AMD was working on it, but I think they got stuck

It is missing this too : https://bugs.freedesktop.org/show_bug.cgi?id=106363

DC is enabled if you are using AMDGPU kernel driver. But it defaults to the radeon kernel driver.

Man this is really not my business to tell who must post what on public forums, but here is fair feedback. I'm kind a super nerd who know more names of Linux graphics stack developers than movie actors and I track this forum, mailing lists and IRC for many years. On top of that I even know at least some publicly known part of RadeonHD story.

Yet even for person like me tone of your posts is just off. Might be you just post it here for Bridgman / Airlie and then it's up to you, but for anyone else this kind of attitude just looks horrible. For someone who're never heard of RadeonHD it's would be just batshit crazy.

Airlie wasn't the one behind KMS? Fine, tell it. They were guys who slowed down open source stack progress? Ok, that insigtful. But personal attacks over decade old events just look crazy.
