            Bug ID: 91294
           Summary: [R7 370] DPM and power profile change crash the system
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: elia.argentieri@openmailbox.org

  --> https://bugs.freedesktop.org/attachment.cgi?id=117032&action=edit
dmesg | grep radeon with radeon.dpm=0

My system is unable to boot with an MSI R7 370 Armor 2X unless I put
radeon.dpm=0 (or nomodeset) to the boot parameter.

Also any change to the power profile results in an immediate lock up with blank
screen or, sometimes, black and white vertical stripes.

I think my issue is related with #77394 and #76490. Probably wrong frequency or
voltages given that the MSI R7 370 Gaming 4G (which is the better version with
higher frequency) works with DPM
(http://www.phoronix.com/scan.php?page=article&item=linux-411-gallium&num=1)

Tested with Linux 3.16, 4.0 and 4.1.

Please attach your full dmesg output and xorg log.  Also attach a copy of your
vbios.

Fix by adding a line to si_dpm_quirk_list

Adding this line made my card work with DPM enabled, but I'm not sure about
mclk value. This card is supposed to have a 5600 MHz video memory according to
MSI's site. However Catalyst reports a frequency of 1400 MHz. Tomorrow, I'll
play with this values.

I have a MSI R7 370 Armor 2x as well and like to report that the suggested
workaround does not help in my case. During the boot process the mouse pointer
is briefly visible but then the screen goes black. I can use the desktop with
radeon.dpm=0. I am returning this card and sticking to my Radeon 6570 for now.

I decided to try to add the quirk line to the debian 4.2.3 kernel source
currently in sid and this time I booted into a stable desktop. The line from
Elia works.

It works, but clocks are really lower than normal. I think that if we use
values from MSI R7 370 Gaming 2G we would be able to make it work with even a
bit higher clocks. Or we could modify VBios of the card with vendor/model
values with ones from that card mentioned before and make the system use all
the things for that card.

Indeed I also tried with higher clock speeds like 1400 and 1300, but all my
attempts had the same outcome. I don't really understand why an higher clock
frequency would lock completely the system as the radeon module is loaded... I
think MSI is doing nasty things like putting a limit inside their firmware to
make the GPU unusable with higher frequencies. I won't ever buy again an MSI
product.

I'm happy to report that I did not need to patch the kernel after upgrading to
kernel 4.5.0 from debian unstable.
