+What: /sys/class/ata_...
+Date: August 2008
+Contact: Gwendal Grignou<gwendal@google.com>
+Description:
+
+Provide a place in sysfs for storing the ATA topology of the system. This allows
+retrieving various information about ATA objects.
+
+Files under /sys/class/ata_port
+-------------------------------
+
+ For each port, a directory ataX is created where X is the ata_port_id of
+ the port. The device parent is the ata host device.
+
+idle_irq (read)
+
+ Number of IRQ received by the port while idle [some ata HBA only].
+
+nr_pmp_links (read)
+
+ If a SATA Port Multiplier (PM) is connected, number of link behind it.
+
+Files under /sys/class/ata_link
+-------------------------------
+
+ Behind each port, there is a ata_link. If there is a SATA PM in the
+ topology, 15 ata_link objects are created.
+
+ If a link is behind a port, the directory name is linkX, where X is
+ ata_port_id of the port.
+ If a link is behind a PM, its name is linkX.Y where X is ata_port_id
+ of the parent port and Y the PM port.
+
+hw_sata_spd_limit
+
+ Maximum speed supported by the connected SATA device.
+
+sata_spd_limit
+
+ Maximum speed imposed by libata.
+
+sata_spd
+
+ Current speed of the link [1.5, 3Gps,...].
+
+Files under /sys/class/ata_device
+---------------------------------
+
+ Behind each link, up to two ata device are created.
+ The name of the directory is devX[.Y].Z where:
+ - X is ata_port_id of the port where the device is connected,
+ - Y the port of the PM if any, and
+ - Z the device id: for PATA, there is usually 2 devices [0,1],
+ only 1 for SATA.
+
+class
+ Device class. Can be "ata" for disk, "atapi" for packet device,
+ "pmp" for PM, or "none" if no device was found behind the link.
+
+dma_mode
+
+ Transfer modes supported by the device when in DMA mode.
+ Mostly used by PATA device.
+
+pio_mode
+
+ Transfer modes supported by the device when in PIO mode.
+ Mostly used by PATA device.
+
+xfer_mode
+
+ Current transfer mode.
+
+id
+
+ Cached result of IDENTIFY command, as described in ATA8 7.16 and 7.17.
+ Only valid if the device is not a PM.
+
+gscr
+
+ Cached result of the dump of PM GSCR register.
+ Valid registers are:
+ 0: SATA_PMP_GSCR_PROD_ID,
+ 1: SATA_PMP_GSCR_REV,
+ 2: SATA_PMP_GSCR_PORT_INFO,
+ 32: SATA_PMP_GSCR_ERROR,
+ 33: SATA_PMP_GSCR_ERROR_EN,
+ 64: SATA_PMP_GSCR_FEAT,
+ 96: SATA_PMP_GSCR_FEAT_EN,
+ 130: SATA_PMP_GSCR_SII_GPIO
+ Only valid if the device is a PM.
+
+spdn_cnt
+
+ Number of time libata decided to lower the speed of link due to errors.
+
+ering
+
+ Formatted output of the error ring of the device.

Hmm... DIPM commands are failing with AC_ERR_OTHER. Other than DIPM
not being configured and speed capped at 1.5Gbps, the machine works
fine afterwards, right? Are you up for applying debug patches?
Thanks.

Yup, it's chugging along happily, though I notice kernel builds are
taking a minute or two longer (but I don't bother to time them so it's
purely subjective.)
Be happy to apply any debug patches, but I plan on replacing the drive
with a faster one at some point in the next few weeks.

Can you please apply the following patch and report the resulting

Hmmm, so it's a timing problem. For some reason, a PHY event is being
reported after reset is complete which unfortunately gets reported
while DIPM command is in progress. Hmmm... what's broken is that the
PHY event happens after reset is complete. Can you please attach the
output of "lspci -nn" and "hdparm -I /dev/sda"? Looks a lot like a
timing issue. Maybe we'll have to add a delay somewhere. :-(

Hmmm... something is setting EH_PENDING while EH is in progress.
Let's see what's doing it. Can you please apply the following patch
on top of the previous one and report the kernel log?
Thanks.

Hi All,
I have two dell laptops 1015. For studying Linux kernel, I want to
let one run debugging Linux as client, the other as host. The two laptops
don't have serial port, just have LAN and usb ports. How can I configure
them to get early kernel print message? I ever asked a lot of people, but
don't get answers. Please give me some practical advices, thanks in advance.

Take a look at <Documentation/networking/netconsole.txt> in the kernel
sources.

My whole dmesg from bootup is available at:
http://kyle.fedorapeople.org/dmesg
There's nothing interesting in my kernel wrt ATA (no patches at all
touching it aside from the two from this thread.) Maybe systemd or
something during boot-up is poking sysfs, I'll take a look.

Yeah, that's expected. Can you please do the usual testing routine
and trigger the EH giving up message and then attach the full kernel
log?
