libata: fix EH device failure handling

2009-02-17T17:29:03+00:00

commit d89293abd95bfd7dd9229087d6c30c1464c5ac83 upstream.

The dev->pio_mode > XFER_PIO_0 test is there to avoid unnecessary
speed down warning messages but it accidentally disabled SATA link spd
down during configuration phase after reset where PIO mode is always
zero.

This patch fixes the problem by moving the test where it belongs.
This makes libata probing sequence behave better when the connection
is flaky at higher link speeds which isn't too uncommon for eSATA
devices.

sata_mv: Fix chip type for Hightpoint RocketRaid 1740/1742

2009-02-06T21:47:24+00:00

commit 4462254ac6be9150aae87d54d388fc348d6fcead upstream.

Fix chip type for the Highpoint RocketRAID 1740 and 1742 PCI cards.
These really do have Marvell 6042 chips on them, rather than the 5081 chip.

Confirmed by multiple (two) users (for the 1740), and by examining
the product photographs from Highpoint's web site.

sata_nv: ck804 has borked hardreset too

2009-02-06T21:47:19+00:00

commit 8d993eaa9c3c61b8a5929a7f695078a1fcfb4869 upstream.

While playing with nvraid, I found out that rmmoding and insmoding
often trigger hardreset failure on the first port (the second one was
always okay).  Seriously, how diverse can you get with hardreset
behaviors?  Anyways, make ck804 use noclassify variant too.

sata_nv: fix MCP5x reset

2009-02-06T21:47:19+00:00

commit 2d775708bc6613f1be47f1e720781343341ecc94 upstream.

MCP5x family of controllers seem to share much more with nf2's as far
as reset protocol is concerned.  It requires heardreset to get the PHY
going and classfication code report after hardreset is unreliable.
Create a new board type MCP5x and use noclassify hardreset.  SWNCQ is
modified to inherit from this new type.

This fixes hotplug regression reported in kernel bz#12351.

nv_nf2_hardreset() will be used by other flavors too.  Rename it to
nv_noclassify_hardreset().

sata_mv: fix 8-port timeouts on 508x/6081 chips

2009-02-06T21:47:16+00:00

commit b0bccb18bc523d1d5060d25958f12438062829a9 upstream.

Fix a longstanding bug for the 8-port Marvell Sata controllers (508x/6081),
where accesses to the upper 4 ports would cause lost-interrupts / timeouts
for the lower 4-ports.  With this patch, the 6081 boards should finally be
reliable enough for mainstream use with Linux.

pata_hpt366: no ATAPI DMA

2008-12-16T10:40:34+00:00

ATAPI device locks up pata_hpt366.  Follow the suit.

pata_hpt366: fix cable detection,

2008-12-16T10:40:32+00:00

pata_hpt366 is strange in that its two channels occupy two PCI
functions and both are primary channels and bit1 of PCI configuration
register 0x5A indicates cable for both channels.
