I was converting a semaphore in this file to a mutex when I noticed that
this file has some fairly rampant style problems. Practically every line
has spaces instead of tabs .. Once I cleared that up, checkpatch.pl showed
a number of other problem.. I think this file might be a good one to review
for new style checks that could be added..
Below are the only two remaining which I didn't remove.
#5083: FILE: drivers/usb/host/u132-hcd.c:2907:
+ error:
WARNING: labels should not be indented
#5087: FILE: drivers/usb/host/u132-hcd.c:2911:
+ stall:
These labels are actually inside a switch statement, and they are right
under "default:". "default:" appears to be exempt and these other label
should be too, or default shouldn't be exempt.
I also deleted a few lines due to single statements inside { } ,
if (is_error()) {
return;
}
becomes,
if (is_error())
return;
with one line deleted.

the following patch uses 16 write urbs and a writsize of wMaxPacketSize
* 20. With this patch I get the maximum througput from my linux system
with 20MB/sec read and 15 MB/sec write (full speed 1 MB/sec both)
I also deleted the flag URB_NO_FSBR for the writeurbs, because this
makes my full speed devices significant slower.

I have got a cypress usb-ide bridge and I would like to tune or monitor
my disk with tools like hdparm, hddtemp or smartctl.
My controller support a way to send raw ATA command to the disk with
something call atacb (see
http://download.cypress.com.edgesuite.net/design_resources/datasheets/contents/cy7c68300c_8.pdf).
Atacb support can be added for each application, but there is some disadvantages :
- all application need to be patched
- A race is possible if there other accesses, because the emulation can
be split in 2 atacb scsi transactions. One for sending the command, one
for reading the register (if ck_cond is set).
I have implemented the emulation in usb-storage with a special proto_handler,
and an unsual entry.

Some EHCI fault paths with large control transfers aren't coded. Avoid
problems by rejecting transfers that may need two qTDs (16+ KB). This is
mostly paranoia; even 4 KB transfers are rare, and most HCDs use lower
limits (so it's unlikely anyone would ever try such a thing).

The cypress app note for the M8 states that for the USB low speed
version of the part, throughput is effectively limited to 800
bytes/sec. So if we were to try a faster baud rate in such cases then
we risk overrun errors on receive. Best to just identify this case
and limit the rate to 4800 baud or less (by ignoring any request to
set a faster rate). The old baud rate setting code was somewhat
fragile; this change also hopefully makes it easier in the future to
better checking / limiting.

Remove a NULL check in cypress_m8; the check is useless in this
context because it is referenced earlier in the same code path thus
the kernel would be oops'ed before reaching this point anyway. (And
it's really pointless here anyway; if this pointer somehow is NULL the
driver is going to have serious problems in many other places.)

cypress_m8: Packet format is separate from characteristic size
The Cypress app note states that when using an 8 byte packet buffer
size that the packet format is modified (to be more compact). However
I have since discovered that newer DeLorme Earthmate LT-20 devices
(those that are low speed USB with 8 byte packet size) STILL use the
format that is really supposed to correspond to 32 byte packets.
Further confusing things is the subsequent discovery that there are
actually two different types of LT-20 - older LT-20's use 32 byte
packets which is probably why this issue wasn't originally
encountered. The solution here is to flag the packet format
separately from the buffer size. Then at initialization time,
identify the correct combination and set it up. This is a critical
fix for anyone with a newer LT-20. Older devices and non-Earthmate
devices should remain unaffected by this change. (If other devices
behave in this, uh, unexpected manner, it's now just a simple 1 line
change to fix them as well (change the pkt_fmt member for that
device). Default behavior with this patch is still to drive the
format as per the app-note; of course for Earthmate devices this is
overridden.

cypress_m8: Feature buffer fixes
From: Mike Isely <isely@pobox.com>
Don't hardcode the feature buffer size; use sizeof() instead. That
way we can easily specify the size in a single spot. Speaking of the
feature buffer size, the Cypress app note (and further testing with a
DeLorme Earthmate) suggests that this size should be 5 not 8 bytes.
