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 thread. vkGetShaderInfoAMD available on RADV (will be filing
optimization bugs). DEVICE_UNCACHED_BIT_AMD works on RADV for
low-latency CPU/GPU. Header-free Vulkan: VkPhysicalDeviceLimits
replaced with 63 64-bit values (504 bytes) for direct byte offset.
Next: another beam-racing effort on Linux, separate queue for
present-only to fully decouple {dispatch, swap}.
