Currently, Panfrost only supports MMU configuration in "LEGACY" (as Bifrost calls it) mode, a (modified) version of LPAE "Large Physical Address Extension", which in Linux we've called "mali_lpae". This commit adds support for conditionally enabling AARCH64_4K page table format. To achieve that, a "GPU optional quirks" field was added to `struct panfrost_features` with the related flag. Note that, in order to enable AARCH64_4K mode, the GPU variant must have the HW_FEATURE_AARCH64_MMU feature flag present. Signed-off-by: Ariel D'Alessandro <ariel.dalessandro@xxxxxxxxxxxxx>
I would've preferred the LEGACY format to be a quirk, instead of AARCH64, but okay. Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxx>
