To: Linux-scsi
1. Create a file "update_bios" in sysfs to allow user to update bios
from user space.
2. The aic94xx BIOS image file can be downloaded from web site
"http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300"
and copy the BIOS image into /lib/firmware folder.
3. The aic994xx will accept "update bios_file" and "verify bios_file"
commands to perform update and verify BIOS image .
For example:
Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios"
to update BIOS image from /lib/firmware/as483c01.ufi file into
HBA's flash memory.
Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios"
to verify BIOS image between /lib/firmware/asc48c01.ufi file and
HBA's flash memory.
4. Type "cat /sys/devices/.../update_bios" to view the status or result
of updating BIOS.

* [PATCH] aic94xx: update BIOS image from user space.

From: Gilbert Wu @ 2007-10-11 1:41 UTC (permalink / raw)
To: linux-scsi
1. Create a file "update_bios" in sysfs to allow user to update bios
from user space.
2. The BIOS image file can be downloaded from web site
"http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300"
and copy the BIOS image into /lib/firmware folder.
3. The aic994xx will accept "update bios_file" and "verify bios_file"
commands to perform update and verify BIOS image .
For example:
Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios"
to update BIOS image from /lib/firmware/as483c01.ufi file into
HBA's flash memory.
Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios"
to verify BIOS image between /lib/firmware/asc48c01.ufi file and
HBA's flash memory.
4. Type "cat /sys/devices/.../update_bios" to view the status or result
of updating BIOS.

You could also optimize "Method A" to write 2 bytes at a time,
iff the flash is "wide".

Hmm, I've found that using the "Poll program" sequence, using DQ7 (DATA#)
and DQ5 (Timeout Status), to be much more reliable, as opposed to
the toggle lines DQ6 and DQ2.

Sometimes this isn't enough and when writing large contents, say
4 or 8 MB you need something like the following:
if (need_resched())
schedule_timeout_interruptible(HZ);
else
udelay(10);
if (signal_pending(current))
return -EINTR;
Else the rest of the system becomes unresponsive and slow
due to the "busy" (and long for large firmware) "udelay".

Ouch! The flash access method doesn't depend on the
manufacturer, but on the width of the flash and on
the way it is actually connected to the EXSI block,
although an 8 bit flash could be connected in only
one way, 16 bit flash could be connected in 8 or
16 bit way. Take a look at the schematic and work
out what goes out XADDRx and into Ax for each sequence
and you'll see it.

It's rather obvious what kfree() does, isn't it?

^^
flash, I'd prefer whitespace before the number. In this form someone
could
think it's a flash index and not the error code on the first look.

* [PATCH] aic94xx: update BIOS image from user space.

To: Linux-scsi
1. Create a file "update_bios" in sysfs to allow user to update bios
from user space.
2. The BIOS image file can be downloaded from web site
"http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300"
and copy the BIOS image into /lib/firmware folder.
3. The aic994xx will accept "update bios_file" and "verify bios_file"
commands to perform update and verify BIOS image .
For example:
Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios"
to update BIOS image from /lib/firmware/as483c01.ufi file into
HBA's flash memory.
Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios"
to verify BIOS image between /lib/firmware/asc48c01.ufi file and
HBA's flash memory.
4. Type "cat /sys/devices/.../update_bios" to view the status or result
of updating BIOS.

* [PATCH] aic94xx: update BIOS image from user space.

From: Gilbert Wu @ 2007-10-12 2:01 UTC (permalink / raw)
To: Linux-scsi
1. Create a file "update_bios" in sysfs to allow user to
update bios from user space.
2. The BIOS image file can be downloaded from web site
"http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300"
and copy the BIOS image into /lib/firmware folder.
3. The aic994xx will accept "update bios_file" and "verify bios_file"
commands to perform update and verify BIOS image .
For example:
Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios"
to update BIOS image from /lib/firmware/as483c01.ufi file
into HBA's flash memory.
Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios"
to verify BIOS image between /lib/firmware/asc48c01.ufi file
and HBA's flash memory.
4. Type "cat /sys/devices/.../update_bios" to view the status or
result of updating BIOS.

1. Create a file "update_bios" in sysfs to allow user to update bios
from user space.
2. The BIOS image file can be downloaded from web site
"http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300"
and copy the BIOS image into /lib/firmware folder.
3. The aic994xx will accept "update bios_file" and "verify bios_file"
commands to perform update and verify BIOS image .
For example:
Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios"
to update BIOS image from /lib/firmware/as483c01.ufi file into
HBA's flash memory.
Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios"
to verify BIOS image between /lib/firmware/asc48c01.ufi file
and
HBA's flash memory.
4. Type "cat /sys/devices/.../update_bios" to view the status or
result
of updating BIOS.
