Hi gentoo-user, |
| 2 |
|
| 3 |
I'm attempting to configure a mid-range video card: the Radeon R7 370. Running |
| 4 |
on the Pitcairn chipset and a member of the Southern Islands family, I am |
| 5 |
surprised at the complexity of setting up the Radeon driver in comparison to its |
| 6 |
NVIDIA counterpart. |
| 7 |
|
| 8 |
I followed [1] carefully. Initially opting to compile AMDGPU into the kernel, I |
| 9 |
emerged linux-firmware with the following files. All of the relevant files were |
| 10 |
added to the kernel's CONFIG_EXTRA_FIRMWARE string, using /lib/firmware as the |
| 11 |
base directory. |
| 12 |
|
| 13 |
radeon/pitcairn_smc.bin |
| 14 |
radeon/pitcairn_ce.bin |
| 15 |
radeon/pitcairn_mc.bin |
| 16 |
radeon/pitcairn_me.bin |
| 17 |
radeon/pitcairn_pfp.bin |
| 18 |
radeon/pitcairn_k_smc.bin |
| 19 |
radeon/pitcairn_rlc.bin |
| 20 |
radeon/TAHITI_uvd.bin |
| 21 |
radeon/TAHITI_vce.bin |
| 22 |
|
| 23 |
Unfortunately, upon booting, the kernel hangs with the following message. This |
| 24 |
seems to be rather common, with a similar complaint being discussed at [2]. |
| 25 |

| 27 |
|
| 28 |
As this all occurs pre-OpenRC, I am incapable of creating an S.S.H.\ connection |
| 29 |
to the machine from my laptop. When booting the kernel with the `nomodesetting` |
| 30 |
parameter, the X server reports the following after a successful kernel boot |
| 31 |
(created when executing `startx`): [timestamps omitted] |
| 32 |

In a fruitless attempt to fix this, I opted to instead load AMDGPU as a kernel |
| 63 |
module. That did not go far either, as apparently a bug exists in the Radeon |
| 64 |
drivers which causes OpenRC to hang when setting the system time according to |
| 65 |
the internal clock [3]: |
| 66 |
|
| 67 |
Setting system clock using hardware clock [Local Time] |
| 68 |
[hangs forever] |

Any help with this would be appreciated. I'm moving away from NVIDIA due to the |
| 71 |
requirement of proprietary drivers to get any decent performance, however now it |
| 72 |
feels as though the AMD drivers, although open-source, consist of too many bugs |
| 73 |
(such as hanging the boot-up process for some reason or another) to be of any |
| 74 |
actual use. Whilst I'm aware that is obviously not the case due to the |
| 75 |
popularity of their cards, I am bewildered at how difficult this seems. |
| 76 |
|
| 77 |
Cheers. |
