2011-09-29staging: nvec: Add myself to MAINTAINERSJulian Andres Klode
I intent to support this code, especially the parts I wrote; and will thus enter as co-maintainer. Signed-off-by: Julian Andres Klode <jak@jak-linux.org> Acked-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-09-29staging: nvec: Add battery quirk to ignore incomplete responsesJulian Andres Klode
The nvec_power system polls nvec for battery information. In some cases, that part seems to be overloaded and unable to respond fast in which case it sends an incomplete response. We need to mark the transfer as completed, though, in order to prevent endless retries which can kill nvec.

2011-09-29staging: nvec: ps2: Always sample 4 bytes instead of just 1Julian Andres Klode
Get 4 bytes of data from nvec at once instead of just a single byte. This makes the driver more similar to nvidias and might improve reliability. Signed-off-by: Julian Andres Klode <jak@jak-linux.org> Acked-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-09-29staging: nvec: Return error in PS2 driver if write failsJulian Andres Klode

2011-09-29staging: nvec: Reject incomplete messagesJulian Andres Klode
Reject incomplete messages, causing the request to be transmitted again. This should fix various problems out there. Signed-off-by: Julian Andres Klode <jak@jak-linux.org> Acked-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-09-29staging: nvec: Handle filled up RX buffersJulian Andres Klode
If no RX buffer is available in state 1, jump to state 0 again. This will produce an incredible amount of warnings, but it is not supposed to happen anyway.

2011-09-29staging: nvec: Allow TX buffers only in the upper 75% of the poolJulian Andres Klode
Allow TX buffers to be allocated only in the upper 75% of the pool to avoid a completely filled buffer preventing the driver from processing responses. This also improves performance, as RX allocations do not require checking buffers allocated for TX unless there are more than 16 incoming messages -- which is highly unlikely. An earlier version used the lower 75% for TX messages, but that was considered to be not that effective due to the overlaps of RX and TX buffers mentioned above.

2011-09-29staging: nvec: Export nvec_msg_free() to clientsJulian Andres Klode
Client code wishing to make use of nvec_write_sync() must have a way to free the returned pointer, otherwise we run out of poool memory fairly soon. Signed-off-by: Julian Andres Klode <jak@jak-linux.org> Acked-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-09-29staging: nvec: Move implementation-only macros out of the headerJulian Andres Klode
Those macros are needed only for implementation purposes and do not have any use for other code wishing to use nvec. Signed-off-by: Julian Andres Klode <jak@jak-linux.org> Acked-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-09-29staging: nvec: Have nvec_write_async() return -ENOMEM on OOMJulian Andres Klode
Change nvec_write_async() to return an integer, 0 by default, a negative error on failure. Change nvec_write_sync() to check the return value and abort if it is negative.

2011-09-29staging: nvec: Enable the capslock LED in the keyboard driverJulian Andres Klode
When the caps lock key is pressed, toggle the associated LED. According to Nvidia code, we should send 0x01 where we sent 0x07, but this does not appear to work correctly on the AC100.

2011-09-29staging: nvec: Add myself to copyright and authors listJulian Andres Klode
Forgotten in the last commit(s) which contained the copyrightable material, so let's add it now. I believe that only my nvec.c contributions are copyrightable, nvec.h is just interface naming, so does not deserve that yet.

2011-09-29staging: nvec: Do not print free message for tx_scratchJulian Andres Klode
The scratch area is not part of the pool and thus gets no allocation message. Printing a free message would be confusing, and the pointer subtraction would be undefined behavior.

2011-09-29staging: nvec: Rewrite the interrupt handlerJulian Andres Klode
Rewrite the interrupt handler to use a state machine similar to that found in the various kernels for the Advent Vega. This also changes the code to use the new functions introduced in the previous commits. This also merges the rewrite sent in August 2011 by Marc Dietrich, and thus also includes code by him. His original patch can be found on the mailing list.

2011-09-29Staging: bcm: Alter LOC for readability/understandability purposesKevin McKinney
This patch alters a line of code to make it more readable and easier to understand. The purpose of the original line of code was to compute the amount of memory to request from kmalloc. This mulit-step algorithm was being done in one line of code, thus making it more difficult to understand. Therefore, I split this algorithm into three logical steps.

2011-09-29Staging: bcm: Add min/max restrictions for IOCTL_BCM_REGISTER_READ_PRIVATEKevin McKinney
This patch fixes two issues within bcm/Bcmchar.c. The first condition in the or statement checks if variable IoBuffer.OutputLength, defined from user space, is greater than the maximum value allowed for an unsigned short. IoBuffer.OutputLength is then used in a kmalloc call to return a pointer to memory. If this size is greater than an unsigned short, it becomes useless. The second condition in the or statement checks if the same variable, IoBuffer.OutputLength is equal to zero before invoking the kmalloc call. In this case, if a zero size is sent to kmalloc, a valid pointer to memory is returned instead of the expected NULL.

2011-09-26staging: gma500: gtt based hardware scrolling consoleAlan Cox
Add support for GTT based scrolling. Instead of pushing bits around we simply use the GTT to change the mappings. This provides us with a very fast way to scroll the display providing we have enough memory to allocate on 4K line boundaries. In practice this seems to be the case except for very big displays such as HDMI. It works out nicely on the usual configurations are netbooks and tablets.
