2-post thread, 1 PNG, 7 likes, 1015 views. Got ALSA functioning without
SNDRV_PCM_IOCTL_HW_REFINE, only with SNDRV_PCM_IOHW_PARAMS. Custom
struct layouts aliased to ALSA's (snd_interval.interger -> .flag=4);
setting the core values is enough for the driver. Doesn't need to
set {.flags, .rmask, .info} but must set '.max=~0' for intervals not
hardcoded. Only double-buffered 48000Hz stereo, varies frames/period
sizing. Same pattern as the bind-everything-once aliasing: write
custom struct, alias to what the API expects, set only the core
fields you control. 'Minimal ABI surface' approach.
5-post design walkthrough of a branch-free 8-bit/word color-forth variant
for code generation: ~62 dict entries/page with paging, call/return
inlined by the compiler, branch-free compile + branch-free execution,
lookup-table pre-compile writes unaligned 8-bytes. Intended for tiny
self-contained chunks that include their own codegen. Whitney-esk in
single-char vars, non-Whitney in no higher-order arrays.
