(As noted by folk whose boards weren't stuck on 2.6.9 kernels...) * Cope with various system-specific issues: - Some configurations (e.g. a CF-card uses this chip) have iospace addresses for the two registers, rather than memory mapped ones. - Some configurations do interesting things with IRQs; maybe the line is shared, or it doesn't support level triggering. - Not all boards can drive the chip reset line in software. * Address a potential race during unlinking. * Tweak probe/remove section info to handle the case where this segment of a platform bus is hotpluggable (e.g. CF card). (The basic problem is that CONFIG_HOTPLUG is global, which is wrong since not all busses can hotplug even on hotplug-friendly systems...) Also export the driver, so that the CF driver can depend on it. Also removed some annoying end-of-line whitespace.

This is a GSM data card, controlled by three "serial ports" which are connected via an OHCI adapter, all located on an oversized PC-Card. It's sold by several GSM service providers. Traditionally, this card has been accessed via the standard serial driver and appropriate vendor= and product= options. However, testing has revealed several problems with this approach, including hung data transfers and lost data blocks when receiving. Therefore, I've written a separate driver.

This patch was originally developed by Daniel Smertnig. I (Ian Abbott) made a few changes. It has been tested by both Daniel and I, at least for raw, non-canonical receive data processing. Here is Daniel's original description of the patch: === During a project in which I was using a FTDI 232BM to transmit data at relative high speeds (625kBit/s), I noticed a problem where data was lost even if flow control was enabled: The FTDI-Driver receives 512 Bytes of data over USB at a time, which consists of 8 64-Byte packets. Subtracting the 2 bytes of status information included in each packet this gives 496 "real" data bytes per read. This data is passed (indirectly, via the flip buffers) to the tty line discipline which takes care of throttling when there the free buffer space reaches TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver processes up to 496 bytes at a time, throttling won't happen in time and the line discipline will discard the remaining bytes. To avoid this the patch passes data in 62-byte blocks to the tty layer and checks the available space in the ldisc-buffers. If there isn't enough free space, processing the rest of the data is delayed using a workqueue. Note: The original problem should be easily reproducible with a userspace program which does slow & small reads. === Signed-off-by: Ian Abbott Signed-off-by: Daniel Smertnig Signed-off-by: Greg Kroah-Hartman --- drivers/usb/serial/ftdi_sio.c | 118 ++++++++++++++++++++++++++++++++---------- 1 file changed, 91 insertions(+), 27 deletions(-) (limited to 'drivers/usb') diff --git a/drivers/usb/serial/ftdi_sio.c b/drivers/usb/serial/ftdi_sio.c index 051c3a77b41..3bfcc7b9f86 100644 --- a/drivers/usb/serial/ftdi_sio.c +++ b/drivers/usb/serial/ftdi_sio.c @@ -264,7 +264,7 @@ /* * Version Information */ -#define DRIVER_VERSION "v1.4.1" +#define DRIVER_VERSION "v1.4.2" #define DRIVER_AUTHOR "Greg Kroah-Hartman , Bill Ryder , Kuba Ober " #define DRIVER_DESC "USB FTDI Serial Converters Driver" @@ -687,6 +687,8 @@ struct ftdi_private { char prev_status, diff_status;

"Obviously safe." It allows some devices to enumerate that previously didn't. We've seen a bunch of these problem reports recently, this will make some go away. As reported by Michael Zapf , some EHCI controllers seem to take forever to finish port resets and produce "port N reset error -110" type errors. Spinning a bit longer helps.

It's checking the device's bus list, which will only appear empty when the device has been initialized, but not added. It depends way too much on the driver model internals, but it seems to be the only way to do the weird crap they want to do with interfaces. When I converted it to use klists, I accidentally inverted the logic, which led to bad things happening. This patch returns the check to its orginal value.

Establish a simple API for process freezing defined in linux/include/sched.h: frozen(process) Check for frozen process freezing(process) Check if a process is being frozen freeze(process) Tell a process to freeze (go to refrigerator) thaw_process(process) Restart process frozen_process(process) Process is frozen now 2. Remove all references to PF_FREEZE and PF_FROZEN from all kernel sources except sched.h 3. Fix numerous locations where try_to_freeze is manually done by a driver 4. Remove the argument that is no longer necessary from two function calls. 5. Some whitespace cleanup 6. Clear potential race in refrigerator (provides an open window of PF_FREEZE cleared before setting PF_FROZEN, recalc_sigpending does not check PF_FROZEN). This patch does not address the problem of freeze_processes() violating the rule that a task may only modify its own flags by setting PF_FREEZE. This is not clean in an SMP environment. freeze(process) is therefore not SMP safe!
