Hello,
The Nemo board (A-EON AmigaOne X1000) [1] and the FSL P5040 Cyrus+ board (A-EON AmigaOne X5000) [2] with installed AMD Radeon HD6970 NI graphics cards (Cayman XT) [3] don't boot with the latest git kernel anymore after the commit "drm/radeon/nislands_smc.h: Replace one-element array with flexible-array member in struct NISLANDS_SMC_SWSTATE branch" [4]. This git kernel boots in a virtual e5500 QEMU machine with a VirtIO-GPU [5].
I bisected today [6].
Result: drm/radeon/nislands_smc.h: Replace one-element array with flexible-array member in struct NISLANDS_SMC_SWSTATE branch (434fb1e7444a2efc3a4ebd950c7f771ebfcffa31) [4] is the first bad commit.
I was able to revert this commit [7] and after a new compiling, the kernel boots without any problems on my AmigaOnes.
After that I created a patch for reverting this commit for new git test kernels. [3]
The kernel compiles and boots with this patch on my AmigaOnes. Please find attached the kernel config files.
Please check the first bad commit.
I'll have a look.
Thanks for the report! -- Gustavo
Thanks, Christian
