request (not always the passed in DMA tag if we try direct-map
and then fall back to sgmap-mapped). Use the actual window
when performing dmamap_sync and dmamap_unload operations.
Fixes DMA resource leak on systems with 2G+ RAM. Thanks to
Matt Thomas for help debugging this.
Arguably this could be moved to using the distrib/miniroot
infrastructure instead.
XXX: This could benefit from being crunchgen-ed with libhack;
currently it just uses a lot of stuff out of ${DESTDIR}
- take advantage of Makefile.mdset
- use list instead of ramdisk.list, and remove special srcdirs for init
and dd since they understand -DSMALLPROG
- use full-path style specfile mtree.conf instead of
old-style specfile ../common/ramdisk.tree
- ensure IMAGEDEPENDS is in sync with list
(xxx; untested :)
file descriptor leak fix.
null encryption algorithm key length fix (should use 0).
couple of null-pointer reference fixes.
set port # to 500 in ID payload (possible interop issue - spec is unclear).
correctly match address pair on informational exchange
- Add support for "setvar", which allows setting of arbitrary wsconsctl(8)
variables. Per email on tech-userlevel from Julio Merino <jmmv@hispabsd.org>
there may be tagged commands still running when we queue a request sense
command.
Solve this by using 2 DSA entry per LUN
- Now that we have the command DSA before select, we can load T/L/Q in
SCRATCHC. This makes the selection timeout handler simpler.
- Avoid a race condition when setting the free flag in the cmd ring (see
comment in the script)
- don't forget to update the ID in the head of LUN table after a sync/wide
negotiation. This fixes the command timeout at the first data command
after negotiation (the bus reset handler did update the ID properly,
so subsequent commands were OK).
- for DMA interrupts, clear fifo if it's not empty. Leaving the fifo dirty
would prevent subsequent interrupts from coming in.
- Various improvements in debug messages
- misc cleanups.
