Hello,

Sorry to bother you but is there anybody collecting patches for hw/display 
to make a pull request before the freeze? This used to be Gerd's area but 
he did not send pulls for quite a while. We have this series:

https://patchew.org/QEMU/20260303024730.1489136-1-chad@jablonski.xyz/

and this one patch already rebased on it:

https://patchew.org/QEMU/20260305233717.1D08F5969F6@zero.eik.bme.hu/

that we would like to include in the next release. Please let me know if 
somebody is taking care of this.

Thank you,
BALATON Zoltan

I hope everybody kept silent so far not because nobody read this but 
because they hoped somebody else might take it. Now with the freeze coming 
I start to worry if there's anybody picking this up. If somebody plans to 
please reply. If nobody does, as ati-vga is used by a MIPS machine maybe 
Philippe could help? Note this: 
https://lists.nongnu.org/archive/html/qemu-devel/2026-01/msg06308.html
So for testing you'd have to change the APER_SIZE but otherwise this is 
something to fix in the machine not in ati-vga so we can't fix it there.

Chad was working on this since last year, it would be a pity to miss this 
release due to not having a maintainer.
