v5.2 supersedes v5.1. Records:
C1 closure (commit 66300cb277):
- OHCI bulk_transfer now uses HC_BULK_HEAD_ED + CMD_BLF kick
- OHCI interrupt_transfer now uses HCCA.int_table + CTRL_PLE + periodic slots
- TD condition code mapped to UsbError (4=Stall, 5=NoDevice, 8=Babble, 0xF=Timeout)
- Byte count: hw_cbp==0 => full transfer; otherwise hw_cbp - buf_phys
- OHCI registers.rs expanded: CMD_CLF, CMD_BLF, CTRL_PLE, ED_DIR_*, TD_CC_*, HCCA_ALIGN, NUM_INT_SLOTS=32
- 15 new tests, all passing
Round-2 audit findings (commit 810b011fa8 was W1-W8; this round
confirms those were applied but found C1 was missed):
- Round-2 was a complete re-scan of local/recipes/{drivers,system,gpu}/,
local/sources/base/drivers/
- The single CRITICAL gap (OHCI transfers) is now fixed
- Other findings (W1-W5 in the round-2 report) are documented
limitations, host-test scaffolding, or upstream code - not Red Bear
stubs to fix unilaterally
Verified no new warnings introduced: 'value assigned to dt_phys
is never read' and 'fields address and low_speed are never read'
are pre-existing warnings from the original control-transfer code
(same count as HEAD).
