Good Morning!!

This is my first Gentoo install in a LOOOOONG time....and much has changed.

I have a Dell Poweredge 2850.

From lspci -k I have:

Code:
09:0d.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV100 [Radeon 7000 / Radeon VE]
   Subsystem: Dell PowerEdge 2850 Embedded Radeon 7000-M
   Kernel driver in use: radeonfb


I'm going through the Xorg install document, and am trying to figure out the new kms thing. I've disabled all kernel frame buffer options as prescribed.

I'm a bit confused what I need to do here:

Quote:
For newer AMD/ATI cards (RadeonHD 2000 and up), emerge x11-drivers/radeon-ucode or sys-kernel/linux-firmware.


During the initial install, one of the steps was to install the linux-firmware. This step has been done.
So, do I not need to emerge the radeon-ucode? Is there a benefit of one vs the other?

Thanks in advance for answers to this and any pointers you might could give me.

Cayenne

This is an old radeon chipset, using xf86-video-ati (VIDEO_CARDS="ati radeon") should automatically pull in all the packages needed. I don't recall if any separate firmware was needed for this video, the firmware packages were more for the newer RadeonHD cards.

I have seen bitrot in the classic Radeon driver, so I hope that the RV100 has not rotted away. I've a few RV250/R200 era cards and they are barely working nowadays...

Thank you for the reply!!

Ok..I'm going with the firmware I already did.

I'm now trying to do the kernel config...and the Xorg guide for the ATI radeon section shows chewing an option called

Code:
## (Enable Radeon KMS support)
Device Drivers --->
  Graphics support --->
  <*>  Direct Rendering Manager --->
[*]      Enable modesetting on radeon by default
[ ]      Enable userspace modesetting on radeon (DEPRECATED)


However, Im in make menuconfig...and I only see this option:
[ ] Enable userspace modesetting on radeon (DEPRECATED)

I don't see the other option that I am supposed to choose....

I'm guessing just go without setting this....does anyone know if the missing option is now located somewhere else?

EDIT:

D'oh!! I guess I should read down the page further...later on it says:

Quote:
Note
Linux kernel >= 3.9 does not have the Enable modesetting on radeon by default anymore as it is already implied by default.


Ok...I'm moving on now....

Thanks in advance,

cayenne
