Hi,
many Power (especially P9) machines use AST graphic cards.
There were many improvements and bug fixes recently on this side and it
would be nice to have those in futur 4.9.x Stretch kernels.
Some of those patches have already been taken in the linux lts 4.9
kernel, namely 4.9.15 :
    - [arm64,powerpc*,x86] drm/ast: Fix test for VGA enabled
    - [arm64,powerpc*,x86] drm/ast: Call open_key before enable_mmio in POST code
    - [arm64,powerpc*,x86] drm/ast: Fix AST2400 POST failure without BMC FW or VBIOS

Since then and still in 4.9.24, there are no other patch for this. Those
that would be nice to have are in this list (ordered from 1st to last to
be applied) :

[not included] 6c971c09f38704513c426ba6515f22fb3d6c87d5 : drm/ast: Fixed system hanged if disable P2A
[    included] 3856081eede297b617560b85e948cfb00bb395ec : drm/ast: Fix AST2400 POST failure without BMC FW or VBIOS

[not included] 94fdc2a86a927b409d9a09ba28bcb08e34f3ac8d : drm/ast: POST code for the new AST2500
[    included] 905f21a49d388de3e99438235f3301cabf0c0ef4 : drm/ast: Fix test for VGA enabled
[    included] 9bb92f51558f2ef5f56c257bdcea0588f31d857e : drm/ast: Call open_key before enable_mmio in POST code

only "[not included]" ones should be needed as 3 of them are already in
4.9.18-1 ; the latter should cause some minor fuzz.

Thanks,

F.
