This is a restructuring for coming changes to nd6 (replacing
llinfo_nd6 with llentry). Once we have a lock of llinfo_nd6,
we need to pass it to nd6_ns_output with holding the lock.
However, in a function subsequent to nd6_ns_output, the llinfo_nd6
may be looked up, i.e., its lock would be acquired again.
To avoid such a situation, pass only required data (in6_addr) to
nd6_ns_output instead of passing whole llinfo_nd6.
Inspired by FreeBSD
the Completion Timeout Prefix/Header Log Capable bit in the AER capability
and control register (ECN: Downstream Port Containment (DPC)).
- Add the Poisoned TLP Egress Block bit (ECN: Enhanced DPC).
- Update Link Capabilities 2 register and Link Control 3 register (ECN:
Separate Refclk Independent SSC Architecture (SRIS))
- ECN: Readiness Notifications (RN)
- Add the Retimer Presence Detect Supported bit in the Link Capabilities 2
register and the Retimer Presence Detected bit in the Link Status 2 register
(ECN: Extension Devices)
we end up storing 0... This means that every entry needs a page. We store
MAX_BSIZE - 1 here, but it would be better to always store (avail - 1) here
so that we don't waste a byte and be consistent.
- Add the Structure Length field in AF capability register.
- Add Enhanced Allocation extended capability ID (ECN: Enhanced Allocation (EA)
for Memory and I/O Resources).
- Add LN System CLS (ECN: Lightweight Notification (LN) Protocol).
- Add ST Upper and Lower bit definitions (ECN: TLP Processiong Hints).
- Add the Global Invalidate bit in the ATS capability register and the PRG
Response PASID Required bit in the Page Request status register (ECN: PASID
Translation)
- Decode ASPM support bit more (ECN: ASPM Optionally)
- Use __BITS()
- aprint_normal is correct for the attach message
- KNF adjustments in code we sync with upstream are a nuisance
- aprint_error{,_dev}() is inappropriate for use in runtime code
Avoids having to manually retype info already in .ioconf.
Also, COMPONENT_SIMPLE -> RUMP_COMPONENT=simple. That way, we can add
other attributes where necessary. As "future directions", the "ioconf"
attribute for RUMP_COMPONENT can just be removed when a driver is
converted to modular and has a proper modcmd.
