When EC is in Polling mode, OS will check the EC status continually by using the following source code: clear_bit(EC_FLAGS_WAIT_GPE, &ec->flags); while (time_before(jiffies, delay)) { if (acpi_ec_check_status(ec, event)) return 0; msleep(1); } But msleep is realized by the function of schedule_timeout. At the same time although one process is already waken up by some events, it won't be scheduled immediately. So maybe there exists the following phenomena: a. The current jiffies is already after the predefined jiffies. But before timeout happens, OS has no chance to check the EC status again. b. If preemptible schedule is enabled, maybe preempt schedule will happen before checking loop. When the process is resumed again, maybe timeout already happens, which means that OS has no chance to check the EC status. In such case maybe EC status is already what OS expects when timeout happens. But OS has no chance to check the EC status and regards it as AE_TIME. So it will be more appropriate that OS will try to check the EC status again when timeout happens. If the EC status is what we expect, it won't be regarded as timeout. Only when the EC status is not what we expect, it will be regarded as timeout, which means that EC controller can't give a response in time. http://bugzilla.kernel.org/show_bug.cgi?id=9823 http://bugzilla.kernel.org/show_bug.cgi?id=11141Signed-off-by: NZhao Yakui <yakui.zhao@intel.com> Signed-off-by: NZhang Rui <rui.zhang@intel.com> Signed-off-by: NAndi Kleen <ak@linux.intel.com>

On some ASUS laptops the ECDT gives the incorrect command/status & Data I/O register address. AK: it seems like the command/data addresses are exchanged. In such case it will cause that EC device can't be initialized correctly. To add the EC dmi table is to fix this issue. If the laptop falls into the EC dmi table, the EC command/data I/O address will be fixed.

Add a mechanism to let the write queue drain naturally before closing the TTY, rather than always losing that data. There is a timeout, so it can't wait too long. Provide missing locking inside acm_wb_is_avail(); it matters more now. Note, this presumes an earlier patch was applied, removing a call to this routine where the lock was held. Slightly improved diagnostics on write URB completion, so we can tell when a write URB gets killed and, if so, how much data it wrote first ... and so that I/O path is normally silent (and can't much change timings).

The "increase cdc-acm write throughput" patch left in place two now-obsolete mechanisms, either of which can make the cdc-acm driver drop TX data (nasty!). This patch removes them: - The write_ready flag ... if an URB and buffer were found, they can (and should!) always be used. - TX path acm_wb_is_used() ... used when the buffer was just allocated, so that check is pointless. Also fix a won't-yet-matter leak of a write buffer on a disconnect path.

Update the CDC-ACM gadget code to support the peripheral-to-host notifications when the tty is opened or closed, or issues a BREAK. The serial framework code calls new generic hooks; right now only CDC-ACM uses those hooks. This resolves several REVISIT comments in the code. (Based on a patch from Felipe Balbi.) Note that this doesn't expose USB_CDC_CAP_BRK to the host, since this code still rejects USB_CDC_REQ_SEND_BREAK control requests for host-to-peripheral BREAK signaling (received via /dev/ttyGS*).

ISP1760 requires a delay of 90ns between programming the address and reading the data. Current driver solves this by a mdelay(1) which is very heavy weighted and slow. This patch applies the workaround from the ISP1760 FAQ by using two different banks for PTD and payload data and using a common wait for them. This wait is done by an additional ISP1760 access (whose timing constraints guarantee the 90ns delay). This improves speed when reading from an USB stick from: $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638 real 1m 15.43s user 0m 0.44s sys 0m 39.46s to $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638 real 0m 18.53s user 0m 0.16s sys 0m 12.97s [bigeasy@linutronix.de: fixed comment formating, moved define into header file, obey 80 char rule] Signed-off-by: NEnrico Scholz <enrico.scholz@sigma-chemnitz.de> Signed-off-by: NSebastian Siewior <bigeasy@linutronix.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Update RX path handling in new serial gadget code to cope better with RX blockage: queue every RX packet until its contents can safely be passed up to the ldisc. Most of the RX path work is now done in the RX tasklet, instead of just the final "push to ldisc" step. This addresses some cases of data loss: - A longstanding serial gadget bug: when tty_insert_flip_string() didn't copy the entire buffer, the rest of the characters were dropped! Now that packet stays queued until the rest of its data is pushed to the ldisc. - Another longstanding issue: in the unlikely case that an RX transfer returns data and also reports a fault, that data is no longer discarded. - In the recently added RX throttling logic: it needs to stop pushing data into the TTY layer, instead of just not submitting new USB read requests. When the TTY is throttled long enough, backpressure will eventually make the OUT endpoint NAK. Also: an #ifdef is removed (no longer necessary); and start switching to a better convention for debug messages (prefix them with tty name).

This patch upgrades the support for the Sierra Wireless TRU-Install feature (i.e. zeroCD) to allow for future support of Linux enabled TRU-Install devices. By default all devices that do not have a Linux enabled TRU-Install device (i.e. the device does not have a Linux package on the virtual CD partition) will be switched into "modem mode." Devices that do contain a Linux package in the TRU-Install virtual CD will be allowed to enumerate as a CD-Rom so that either (a) a user can install the packaged software or (b) a user-space application (e.g. udev) can switch it to modem mode. This patch does allow for manual override by adding a usb-storage module parameter 'swi_tru_install' which can force the modem into either mode regardless of what packages it contains.
