           Summary: Radeon with KMS and UMA works only up to 128MB
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.3-rc7
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: j.fikar@gmail.com
        Regression: No


Hardware: Asus M4A88TD-M EVO with integrated Radeon HD 4250 (RS780)

Description: in bios I can choose UMA from 32MB up to 1024MB, but only values
up to 128MB work. Higher values lock the console in text mode before switching
to KMS. It also happens on older kernels with KMS (2.6.27), but the console is
not locked, the radeon module oopses and resolution stays VGA.

There is also option to locate UMA "above 4G" or "below 4G" in bios, it doesn't
matter. Also it has 128MB of sideport memory, this option doesn't matter
neither. (I have it off for now).

vramlimit parameter doesn't matter either.

System is x86_64, 16GB ECC DDR3 RAM.

Looks like the bios sets up the vram size wrong for values > 128 MB.  Can you
print the value of the CONFIG_MEMSIZE register (0x5428) when you select various
vram sizes over 128 MB?  You can either use radeonreg
(http://cgit.freedesktop.org/~airlied/radeontool/):

radeonreg regmatch 0x5428

or the following patch:

for 128MB it shows this:

./radeontool regmatch 0x5428
0x5428  0x08000000 (134217728)

but

./radeontool regs | grep MEMSIZE
RADEON_CONFIG_MEMSIZE   00000000


is this it? I'll add values for 256MB later.

radeontool is for older chips.  The register is at a different location on
them.  Note I said radeonreg rather than radeontool, but either will work as
long as you specify the proper offset (0x5428).

for 256MB, 512MB and 1024MB I get

[    6.301475] [drm] CONFIG_MEMSIZE: 0xffffffff

also I need a cold restart when changing UMA size in bios, otherwise it's not
changed.

so is it a bios problem? should I try to complain to Asus? Is there an easy
workaround? Like using manually vramlimit?

Looks like the bios is broken.  The vramlimit parameter should work.

vramlimit didn't work, it's in my first post;
but I'll verify that.

[Bug 42920] Radeon with KMS and UMA works only up to 128MB

[bugzilla-daemon]

ok, so vramlimit works, but doesn't solve my problem.

I have tried 128MB UMA with vramlimit=64 and then 256MB UMA with vramlimit=64.
The memory gets smaller, but is wrongly located? 

128MB:
[    7.005921] radeon 0000:01:05.0: VRAM: 128M 0x00000000C0000000 -

256MB:

[    6.663271] [drm] PCIE GART of 512M enabled (table at 0x000000FFFF040000).

There is also change of the RAM width (32bits in working case against 128bits
in the not working case), but maybe that's not important.

the full dmesg -i -E "drm|radeon" is here:

The problem is solved! I forgot I have a custom dsdt.hex, created with small
amount of UMA memory. Removing the custom dsdt.hex solves the problem:
