Using more than 3.5GB RAM

Post by xeno74 »

Hi All,

It is possible to use more than 3.5GB RAM on Linux if you don't have any PCI cards installed in the PCI slots. If you need a PCI card then please install it in a PCIe x1 slot with a PCIe x1 to PCI adapter.

Christian,
This is good news. Do we have a way to use the on-board Ethernet port yet? The only PCI card I use is a networking card.

Hi All,

The problem with the 3.5GB RAM restriction has been fixed. :-)

The MATE PowerPC Remix 2017 with the RC6 of kernel 4.13 on an AmigaOne X5000:

Cool! So you mean that we can have
  • More than 4G RAM
  • HW accelerated 3D
  • PCI cards
all at the same time? And it's 4.13 that makes it possible?

Awesome! I've been running with software 3D forever because I don't want to give up my 16G RAM...

HW accelerated 3D
yes and no.
the bigendian is not full compositing accelerated for 2d or better is not on lightdm , sddm, gnome ... only kde5 have some parts using compositing and is full endianess in color.
The compositing is totally deactivated on firefox this made browsing using the cpu only for rendering and made the browser slow like on an ps3

Tested with kernel 4.13-RC6 using no uboot memory constraints, works nicely! (on MATE PowerPC Remix 0.7)

Any chance we can see this fixed for SI Cards all x1000 users have moved to because of Enhancer,
and x5000 users are coming with?

Its more then just wrong colours, even basic GNOME fails to work as supposed,
as opossed to having the same with previous Radeon 6870 (now 7000). Performance
is really degrading until that done.

Please try to fix this first with Linux teams, new Kernel releases can wait.
