Brandon Schneider	a8b79845b6	feat(infra): add ETHERNET compute tier for virtio-net PistPacket DMA ... New tier between CPU_FFMPEG and FRAMEBUFFER: GPU_CUDA(7) > GPU_VAAPI(6) > GPU_APU(5) > CPU_FFMPEG(4) > ETHERNET(3) > FRAMEBUFFER(2) > ESP32(1) > RELAY(0) - _detect_virtio_net(): probes /sys/class/net for virtio driver (0x1af4) - PistPacket computation via TX/RX descriptor rings - Host vhost-user backend does matrix transforms - CRC32 hardware offload = witness verification - Works in any VM with network (even without framebuffer)	2026-05-30 20:02:06 -05:00
Brandon Schneider	c73e9c4f02	fix(infra): handle Cirrus Logic virtual VGA and DRM naming edge cases ... - Add Cirrus Logic (0x1013) and virtio (0x1af4) to vendor map - Fix DRM card parsing for names like "card0-VGA-1" - Virtual GPUs (cirrus, virtio) never classified as discrete - Virtual GPUs skip VA-API tier, fall to FRAMEBUFFER Racknerd microVM (2vCPU, 715MB, Cirrus VGA) correctly classified as FRAMEBUFFER tier: 1024x768 @ 16bpp = 1.57 MB DMA backplane.	2026-05-30 19:59:38 -05:00
Brandon Schneider	ce0367405b	feat(infra): device capability probe with framebuffer fallback ... device_capability_probe.py: classify every device into a compute tier. Tiers (highest to lowest): GPU_CUDA — NVIDIA discrete + CUDA (NVENC, Ray GPU worker) GPU_VAAPI — AMD/Intel discrete + VA-API (hardware encode) GPU_APU — AMD integrated, yuvj420p, bandwidth-optimized CPU_FFMPEG — Software encode only (libx264) FRAMEBUFFER — /dev/fb0 DMA backplane (8.29 MB/frame at 1080p) ESP32 — MCU, Q0_16 scalar in FreeRTOS idle hook RELAY — Network only, no compute OFFLINE — Unreachable Features: - Multi-GPU DRM render node scanning (card0=AMD, card1=NVIDIA) - APU vs dGPU classification via device name + VRAM heuristics - Framebuffer detection with /sys/class/graphics/fb0 resolution - Ray scheduling helpers (get_ray_placement_strategy) - Cluster probe via SSH - JSON + human-readable output	2026-05-30 19:57:07 -05:00
