esperemos que sim, como a intel precisava já de concorrência a nvidea também, mas neste caso para baixar de preço as gráficas da nvidea pois a nvidea até tem evoluído muito mais que os cpu da intel desculpem, não registo
https://lists.freedesktop.org/archives/amd-gfx/2020-June/049968.html?print=anzwixSienna Cichlid is a GPU from AMD. This patch set adds support for it
including power management, display, kfd, interrupts, gfx, multi-media,
etc. The new register headers are really big so I haven't sent them to
the list. You can view the new patches including the register headers
on the following git branch:

https://www.phoronix.com/scan.php?page=news_item&px=AMD-Sienna-CichlidIt's quite possible Sienna Cichlid is the "big Navi" / RDNA2 GPU. AMD developers have talked before of using alternative codenames when volleying patches early for their open-source Linux driver stack as to not reveal the product/marketing codenames, which could be the case here. This is the first time we are hearing of Sienna Cichlid or seeing any references on the web of it related to AMD.
[PATCH 000/207] Add Support for Sienna Cichlid

Sacanas, agora para a malta não procurar os ID das placas nos patches dos drivers open source inventam nomes para as placas

O suporte da "Sienna" foi adicionado ao Staging DRM-next, que é uma espécie de repositório para os developers testarem os patches antes de serem efectivamente enviados para o DRM-next. Mas podem ali ficar durante algum tempo
Basicamente isto apenas adiciona o suporte da placa ao driver em si, o amdgpu, permitindo usar e testar a mesma.
Como já existiram leaks no passado, não é assim tão difícil perceber o que é aquela "Sienna Cichlid":

Haha muito bom.
Nunca deve ter havido tanta gente a olhar para patches do amdgpu
At the Bank of America 2020 Securities Global Technology Conference, AMD's Devinder Kumar, the company's Chief Financial Officer, has confirmed that Navi 2 will be AMD's "first RDNA 2 base product". This statement suggests that their RDNA 2 architecture will arrive on PC before it becomes available on next-generation consoles.
Both the PlayStation 4 and Xbox Series X are due to release within the "Holiday 2020" timeframe, which means that PC gamers should expect to see RDNA 2 before November 2020.
https://www.overclock3d.net/news/gpu_displays/amd_claims_that_big_navi_will_be_their_halo_product/1Kumar revealed that "the RDNA 2 architecture goes through the entire stack", saying that "it will go from mainstream GPUs all the way up to the enthusiasts and then the architecture also goes into the game console products, ... as well as our integrated APU products." That's right, RDNA 2 is coming to AMD's entire product stack, and that will include APUs (AMD CPUs with integrated graphics), and that's a big deal for AMD's future mobile processors.
AMD's CFO then talked about CDNA, AMD's compute-focused graphics architecture. Kumar stated the following;
"There are some gaming features that are not needed in compute. And then there are some compute features that are not needed in gaming. So to gain efficiency and performance, we have decided to bifurcate the architecture.
We see this area as a tremendous growth opportunity for both gaming and data center GPUs over the next five years, and the bifurcation of our roadmap will allow us to optimise for the workload and for the used cases that we see so that we can grow revenue in the GPU space."
With the Sienna Cichlid enablement for RadeonSI being quite small thanks to largely re-using the existing Navi/GFX10 code paths, the review went quick and as of yesterday the support was merged.
Therefore with Mesa 20.2 the OpenGL driver support is in place.
https://www.phoronix.com/scan.php?page=news_item&px=Sienna-Cichlid-SI-MergedMesa 20.2 should be releasing as stable around late August. However, this support is contingent upon the AMDGPU DRM driver support that isn't landing until Linux 5.9. The Linux 5.9 merge window opens in August and won't be out as stable until around October. Navi 2 GPUs are likely to be releasing around that time, likely meaning all of the open-source support will be available albeit not yet shipping out-of-the-box by the autumn Linux distributions aside from the rolling release distros.
With this initial batch of AMDGPU changes for Linux 5.9 there is a lot of exciting feature work:
- The "Sienna Cichlid" support that was first published a few weeks ago is part of this pull
https://www.phoronix.com/scan.php?page=news_item&px=AMDGPU-Linux-5.9-Round-1The Mesa support and other areas of the Sienna Cichlid support are getting ironed out in parallel with Linux 5.9 to be the first kernel providing out-of-the-box support for the next-gen highly-anticipated GPU.
