Robert Allan JamesandClaude Sonnet 5 2c34e45d05 Artemis Milestone 2f: EP0 control transfer, device descriptor request
Adds Setup/Data/Status stage TRB types and control bits (IDT, TRT, DIR)
to xhci.h, and xhci_ep0_enqueue_trb()/xhci_ep0_get_device_descriptor() to
xhci.c -- the first real control transfer this driver has issued.
Follows the same enqueue-then-doorbell-once pattern as the Command Ring,
operating on the EP0 Transfer Ring built during 2e's Address Device work.
Setup Stage uses Immediate Data (parameter IS the 8-byte setup packet);
Data Stage reads into a reused 18-byte device_descriptor buffer; Status
Stage alone carries IOC, so exactly one Transfer Event signals transfer
completion, correlated via a new pending_transfer_slot_id (same
single-outstanding-operation pattern as connect/Enable Slot/Address
Device).

Automatically triggered once Address Device succeeds. Verified live via
QMP hotplug, all three architectures, worked first try with identical
results everywhere: idVendor=0x46f4, idProduct=0x0001, bDeviceClass=0x00
-- the class=0 confirms Mass Storage class detection needs the
Configuration/Interface descriptor (2f's next item), not the device
descriptor.

logs/

QEMU acceptance-run history and Tripod smoke-test results.

  • <timestamp>/{amd64,aarch64,riscv64}/ — 255 timestamped three-arch QEMU acceptance run directories, one per invocation of the kernel QEMU acceptance workflow.
  • qemu-screenshot-*.png, qemu-screenshot-*.log, qemu-{amd64,aarch64,riscv64}-*.log, fbtest-console-*.png — loose timestamped QEMU serial captures and framebuffer screenshots from individual manual runs (not part of the timestamped-directory convention above).
  • hermes-tripod-smoke-results.md, hermes-channel-smoke-results.md — captured output from tools/hermes_tripod_smoke.sh and tools/hermes_channel_smoke.sh.
  • hermes-tripod-integration-design.md — design notes for the Tripod integration test.

Note: QEMU_BASELINE.log at the repo root (not in this directory) is the primary kernel regression baseline referenced by .claude/CLAUDE.md; the logs here are supplementary historical captures. See also logs2/ (a separate, flatter QEMU log archive) and experiments/bare_metal/runs/ (DoE-specific run output).
