Hi https://cgit.freedesktop.org/~agd5f/linux/plain/drivers/gpu/drm/amd/include/asic_reg/vega10/NBIO/nbio_6_1_sh_mask.h?h=amd-staging-4.9&id=9555ef0ba926df25d9a637d0ea21bc0d231c21d2 The file nbio_6_1_sh_mask.h is uncompressed. It consists from 133884 lines. Only generated C/C++ code will be able to utilize the content of such a file efficiently. All hand-written codes combined will be able to utilize about 1% of the file. Is there a reason why nbio_6_1_sh_mask.h is huge? Jan
