The io-pgtable code constructs an array of init functions for each page table format at compile time. This is not ideal, as this increases the footprint of the io-pgtable code, as well as prevents io-pgtable formats from being built as kernel modules. In preparation for modularizing the io-pgtable formats, switch to a dynamic registration scheme, where each io-pgtable format can register their init functions with the io-pgtable code at boot or module insertion time.

I guess we want to print the format here? Thanks, Georgi _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
