2011-05-16nvrm: move stale wait checking into the kerneltegra-11.2.6Chris Johnson
The kernel now receives wait tracking data (similar to gathers and relocs) and compares the current syncpt with the threshold value. If it's old, it gets a kernel mapping and rewrites the method data to use a kernel reserved syncpt that is always 0 (so trivially pops when seen by the HW). Bug 519650 Bug 785525 Bug 803452 Note: reset the author in this commit to fix a email addr problem and since from the latest/last cherry pick there was a reworking of the code to be compatible with different user space versions it also seemed reasonable.

2011-05-09serial: core: Restore termios settings on resume console portsVandana Salve
The commit 4547be7 rewrites suspend and resume functions. According to this rewrite, when a serial port is a printk console device and can suspend(without set no_console_suspend flag), it will definitely call set_termios function during its resume, but parameter termios isn't initialized, this will pass an unpredictable config to the serial port. If this serial port is not a userspace opened tty device , a suspend and resume action will make this serial port unusable. I.E. ttyS0 is a printk console device, ttyS1 or keyboard+display is userspace tty device, a suspend/resume action will make ttyS0 unusable. If a serial port is both a printk console device and an opened tty device, this issue can be overcome because it will call set_termios again with the correct parameter in the uart_change_speed function. Refer to the deleted content of commit 4547be7, revert parts relate to restore settings into parameter termios. It is safe because if a serial port is a printk console only device, the only meaningful field in termios is c_cflag and its old config is saved in uport->cons->cflag, if this port is also an opened tty device, it will clear uport->cons->cflag in the uart_open and the old config is saved in tty->termios. refer http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.37.y.git; a=commit;h=891b9dd10764352926e1e107756aa229dfa2c210 cherry-pick the changes from the kernel 2.6.37 commit id :891b9dd10764352926e1e107756aa229dfa2c210 Cherry-picked http://git-master/r/#change,20302 Bug 819016 Change-Id: Ic7ce0a6d595c0e1f65285d7978db93be12158f0f Reviewed-on: http://git-master/r/30680 Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com> Tested-by: Bharat Nihalani <bnihalani@nvidia.com>

2011-04-19rtc : tps6586x: avoid RTC time is getting slowertegra-10.11.8Daehyoung Ko
To ensure an accurate read of the RTC registers during the required multi-byte read operation, the PMU RTC is designed with the following protection scheme - A circuit detects a write/read and locks the RTC_COUNT4 value by keeping the RTC in a suspended mode - During the suspended mode, a secondary counter is used to keep track of all counts that would have normally incremented the RTC - After the read is complete, the value of the secondary counter is added back to the RTC registers and thereby keeping the RTC accurate - The backup counter allows for a 1ms RTC suspend mode duration when the RTC prescaler is enabled. i2c needs to generate a 2 msgs when reading. - the address setup(write RTC_COUNT4 operation), hence start locking the RTC_COUNT4 - the data transfer (read RTC_COUNT4 operation),release locking it. this may allow the CPU to execute other portions of code in between the two operation. The fix is to start a PMU RTC access by reading the register prior to the RTC_COUNT4 so that access of the RTC PMU registers will be guaranteed to always occur within the 1ms time period. - the address setup(write RTC_COUNT4-1 operation), so there is no locking the RTC_COUNT4 - the data transfer (read RTC_COUNT4 operation), starting locking the RTC_COUNT4 and release locking the RTC_COUNT4 in one operation, so it will be guaranteed within 1ms Bug 811075 Change-Id: Ie07472a329f6a0eed11e6a039cd93307bb5276a0 Reviewed-on: http://git-master/r/27537 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com>

2011-04-19net: Reorder incoming packets in PPPoLAC and PPPoPNS.Chia-chi Yeh
PPP handles packet loss but does not work with out of order packets. This change performs reordering of incoming data packets within a sliding window of one second. Since sequence number is optional, receiving a packet without it will drop all queued packets. Currently the logic is triggered by incoming packets, so queued packets have to wait till another packet is arrived. It is done for simplicity since no additional locks or threads are required. For reliable protocols, a retransmission will kick it. For unreliable protocols, queued packets just seem like packet loss. Time-critical protocols might be broken, but they never work with queueing anyway. Signed-off-by: Chia-chi Yeh <chiachi@android.com>
