staging: most: aim-cdev: make syscall write accept buffers of arbitrary size

2016-09-23T17:00:44Z

This patch allows to call the write() function for synchronous and isochronous channels with buffers of any size. The AIM simply waits for data to fill up the MOST buffer object according to the network interface controller specification for streaming channels, before it submits the buffer to the HDM. The new behavior is backward compatible to the old applications, since all known applications needed to fill the buffer completely anyway.

staging: most: make function most_submit_mbo return void

2016-09-22T09:54:46Z

Function most_submit_mbo() causes an exception only if either the pointer mbo or mbo->context equals NULL. From the underlying architecture's point of view both cases must _not_ come true and would happen only, if something has tampered with the pointers. This would render runtime code unable to recover anyway. So, instead trying to hide that things are already critically out of control we're better off with a WARN_ON() assertion. This patch replaces the return type of the function most_submit_mbo() with 'void' and adds a WARN_ONCE() assertion. Additionally, code calling the function is adapted accordingly.

staging: most: aim-cdev: destroy ida struct in case of exception

2016-08-22T20:41:00Z

This patch is needed to clean up the initialized ida structure in case the function exits with an exception. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: aim-cdev: report error returned by alloc_chrdev_region

2016-08-21T14:50:38Z

This patch forwards the error code returned by function alloc_chrdev_region(). It is needed to stop the module from hiding the actual cause of failure. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: aim-cdev: fix reported error codes

2016-08-21T14:50:38Z

Currently, the aim-cdev is returning different error codes for the same root cause. This patch is needed to get rid of the module's inconsistency when reporting errors. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: return error value

2016-02-12T03:40:02Z

On error we were returning retval, but retval is not having the error value. We will get the error value using PTR_ERR. Signed-off-by: Sudip Mukherjee Signed-off-by: Greg Kroah-Hartman

staging: most: remove 2nd forward declaration of struct most_aim

2016-02-08T01:34:58Z

This patch removes the second forwared declaration of struct most_aim. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: rearrange function aim_write

2016-02-08T01:34:58Z

This patch straightens and rearranges the code of function aim_write() of module aim-cdev. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: remove stacked_mbo

2016-02-08T01:34:58Z

This patch makes use of kfifo_peek and kfifo_skip, which renders the variable stacked_mbo useless. It is therefore removed. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: change type of access_ref

2016-02-08T01:34:58Z

This patch changes the type of the access reference from atomit_t to int. It is needed, because the reference variable is secured by synchronization locks and does not need to be atomic anymore. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman
