Bug ID: 99261
Summary: Kernel 4.10-rc2 on APU with Kaveri + Topaz : boot
hangs on switch to amdgpudrmfb
Product: DRI
Version: XOrg git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: blocker
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org

kernel log on boot failure
Since testing kernel 4.10 preRC, RC1 and RC2, my laptop hangs on boot at line
fb : switch to amdgpudrmfb from EVI VGA.
A few specs :
APU : AMD A10-7300 Radeon R6, 10 Compute Cores 4C+6G (from /proc/cpuinfo).
iGPU : 00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri
HDMI/DP Audio Controller
dGPU : 01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Topaz
XT [Radeon R7 M260/M265 / M340/M360 / M440/M445]
Xorg : 1.18.4, on Arch Linux
Boot command line : BOOT_IMAGE=/boot/vmlinuz-linux
root=UUID=76ba28b4-683c-4a39-96ef-6a1105905567 rw acpi=off (I have to use
acpi=off on 4.10-rcX to go beyonf initramfs loading)
Whatever amdgpu module's option combination I use is of no avail. These ones
(aspm=0 bapm=0 runpm=0 powerplay=1) allow me to use amdgpu on 4.9.
Attached is a kernel.log file where there is a stack trace of amdgpu module
crashing.
I can use 4.10-rc2 on my desktop with RX480 and an old Phenom II x6 CPU.
I am posting here in the hope of getting developer attention to care about this
module's crashing, on KMS seemingly. If I use nomodeset, the module gets
loaded, but obviously, there's no X session beyond.
Regards.

The driver is not able to find the vbios:
Jan 3 16:28:52 hp2 kernel: [ 10.626851] [drm:amdgpu_get_bios [amdgpu]]
*ERROR* Unable to locate a BIOS ROM

I tried to bisect for the first time, here's what I did :
git bisect start
git bisect bad
git bisect good v4.9
Bisecting: 5782 revisions left to test after this (roughly 13 steps)
[72cca7baf4fba777b8ab770b902cf2e08941773f] Merge tag 'staging-4.10-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
... compile ... The resulting kernel loads amdgpu with a usable X.
git bisect good
Bisecting: 2865 revisions left to test after this (roughly 12 steps)
[775fadd09e7beac2fc61cc0517629e9fa69bdb56] Merge tag 'armsoc-defconfig' of
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Now I don't know what else to do !
This patch seems to indicate locating vbios is being reworked, something is
probably left out.

if things work:
git bisect good
of things don't work:
git bisect bad
and continue until it's done.

That code is not upstream yet. We haven't really touched the vbios fetching
code in a long time, so if you are seeing a regression, it's probably somewhere
else.

Well, the hang up on switch to amdgpudrmfb was due to the kernel boot parameter
'acpi=off' I had to use to go beyond the 'loading initramfs' step. Initial
hangup in the latter step was due to a UEFI bug of the laptop.
Fortunately, the manufacturer provides a BIOS update with the tag 'UEFI
security enhancement'. After flashing the new BIOS, the laptop boots with
kernel 4.10-rc2, with a few errors related to amdgpu, which I'll report in a
new post.
Sorry for the inconvenience.
