libata git tree, mbox queue status and contents

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
