This is a quick guide to current libata work that is queued or in
progress in some way, shape or form.
First, a guide to the branches currently in use in
git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev.git
ALL
Everything that is exported for testing (and akpm's -mm tree).
Currently consists of upstream-fixes + upstream + sil680-mmio branches.
master
Vanilla upstream linux-2.6.git tree.
mv-ahci-pata
Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller
command' area before it is usable, and can go upstream.
mv-ncq
sata_mv NCQ support. Code is complete and /should/ be working, but it
does nothing but timeout and fallback to non-NCQ here. Needs debugging
before can go upstream.
new-eh
Convert sata_qstor and sata_sx4 to new EH. Each needs
testing/verification before it can go upstream.
pmask
Add proto_mask to LLDDs, alongside pio_mask, udma_mask, etc.
sii-lbt
Enable Large Block Transfer mode on sata_sil. Verified to work locally,
but some bug reports on the 'net need to be tracked down before this can
go upstream.
sil680-mmio
BenH's MMIO patch for pata_sil680. Some MMIO/flushing type issues were
raised on the list, a solution was reached. That solution must be coded
before this can go upstream.
upstream
Everything queued for 2.6.24. Includes everything in upstream-fixes.
upstream-fixes
Everything queued for 2.6.23-rc. This tends to go upstream rapidly.
mbox queue, prefixed by author:
* Kristen: ALPM patches. We definitely want them, as they save a ton of
power.
* Tony Vroon: LED trigger.... hmmm
* Alan: IORDY handling -- upstream whenever Alan is happy
* Tejun: improved probe info printout. Want to test and review in
depth, but probably OK
* Alan: ACPI checks for 80wire cable -- upstream whenever Alan is happy
* Tejun: Port Multiplier Support -- I still need to review in depth,
but would like go ahead and push ata_link in
* NVIDIA: sata_nv SW NCQ: need to review WRT FIS state machine, though I
saw some flaws in there. OK if that is OK.
* Albert: irq_on/off. Really need to give this some thought. Not sure
I like where this model is going. Polling and twiddling irq on/off
should be kept to a minimum, because it's sorta an admission that the
host state machine has broken down, and we need to bandaid. Its a
bandaid not a root-cause solution.
* Albert: minor PIO fixes. Need to review in depth.
* Kristen: AN: it seems that things got stuck once Al Viro voiced an
objection?
* Ben Collins: cleanup HPA support. Need to review and see what's
needed today, from this patch.
