Hello all,
this patch in needed in addition to the previous one make suspend/resume work in the forced ahci mode.
This remark should probably follow --- tear line (after the signoff).
During resume from suspend to ram, the kernel pci layer restores the registers for the SATA controller once, then says okay, and sets dev->state_saved = false. However, since the restore goes from highest address (the BARs [base address registers]) to lowest register, some of the higher registers are set as RO because according to the lower registers controller is in PIIX mode. This patch introduces a workaround for this problem, hacking around the PCI API by setting pdev->state_saved = true before we do the restore, basically leaving the pci config space untouched.
Bye,
Joerg
"Hello" and "bye" shouldn't be the part of the patch description.
