Perhaps. Actual
Patch 03: Have sata_promise use the perfect, flawless API from the
previous patch
As described in the archives, this patch build on patch 02 in the
series to actually allow the sata_promise controller to hotswap. Be
careful, untested!
This version comes with all of Jeff's suggestions (documente
Patch 02: Add a hotswap infrastructure to libata
As described in the archives, this patch adds a framework and API to
libata to allow for hotswapping.
This version comes with a debounce timer... exciting!

Patch 01: add promise SATAII150 support to the sata_promise driver.
As described in the archives, this patch adds support for those
notorious SATAII150 controllers with their weird hotplug offset and
prepares us for hotplug goodness.
Jeff: The reason that ATA_FLAG_SATA is commented out on pdc_2
Hey Jeff, all,
The following is my latest attempt at re-doing the hotswap patches for
libata hotswapping. This has some positive upsides:
- The patches seem cleaner
- The patches seem more multi-purpose and adaptable for use across all
controllers, not just the Promise ones.
- Jeff is more likel

Excellent! Thanks for the quick turnaround!

Hey Jeff, everyone.
This is a resend of patch 3 of my libata hotswap series, wherein I
found a silly flaw in my logic. I don't know what kind of crack I was
smoking, but I somehow turned "a = a & ~b" in the Promise driver into
"a = a ^ b" in my hotswap code, which is clearly wrong. I don't know

still works. I think.
And (again, I think) this same problem exists with 2.6.11 as well.
At least, I wasn't able to remove-single-device even once (I discovered

This patch is probably the most contentious one; adding a hotswap
framework to libata to allow it to handle disk plugs/unplugs.
The design goals for this framework were as follows:
- easy, stable API.
- simplicity of design and code
- as damn near as we can get to a guarantee that we will NOT pa
This patch is an implementation of hotswap on the sata_promise module,
tested on SATA150 and SATAII150 Promise controllers. It depends on
patch 01 from this series of patches to apply, and both 01 and 02 in
order to compile.
We handle hotplug interrupts and call our new API functions in libat
This patch changes the sata_promise driver in libata to correctly mask
out hotplug interrupts. The location of the primary hotplug registers
in the SATA150 Tx4/Tx2 Plus controllers is correctly defined as '0x6C',
HOWEVER, for the SATAII150 Tx4/Tx2 Plus controllers, this changes to
'0x60'. Thi
Hey all, introductory blurb here.
This sequence of patches will add a framework to libata to allow for
hot-swapping disks in and out.
There are three patches:
01-promise_sataII150_support
02-libata_hotswap_infrastructure
03-promise_hotswap_support
The rationale for each will be described in f
Hello all,
I'm currently working on a project to get a true disk-hotplug subsystem
working in libata, experimenting with Promise SATA150 Tx2 Plus and
SATAII150 Tx2 Plus controllers.
I am very near a 'beta' release of my patches to this mailing list,
however, I have hit a stumbling block in t
