2016-03-09iwlwifi: mvm: adapt the firmware assert log to new firmwareEmmanuel Grumbach1-4/+4
Newer firmware versions put different data in the memory which is read by the driver upon firmware crash. Just change the variable names in the code and the name of the data in the log that we print withouth any functional change. On older firmware, there will be a mismatch between the names that are printed and the content itself, but that's harmless. Signed-off-by: Emmanuel Grumbach <[email protected]>

Since the PNs of all the tx keys are now tracked in the public part of the key struct (with atomic counter), we no longer need these functions. dvm and vt665{5,6} are currently the only users of these functions, so update them accordingly.

2016-02-01iwlwifi: dvm: handle zero brightness for wifi LEDHubert Tarasiuk1-1/+4
In order to have the LED being OFF constantly when the brightness is set to 0, we need to pass IWL_LED_SOLID to iwl_led_cmd as the off parameter, otherwise the led will stay on constantly.

2016-02-01iwlwifi: mvm: Do not switch to D3 image on suspendMatti Gottlieb1-2/+2
Currently when the driver is configured with wowlan parameters, and enters D3 mode, the driver switches the FW image to D3, and when it exists suspend, it reloads the D0 image. If the firmware supports the consolidation of the D0 & D3 images there is no need to load the D3 image on suspend, and no need to reload the D0 image on resume. Do not switch images on suspend / resume, for firmwares that support consolidated images. Signed-off-by: Matti Gottlieb <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2016-01-16include/linux/kernel.h: change abs() macro so it uses consistent return typeMichal Nazarewicz1-1/+1
Rewrite abs() so that its return type does not depend on the architecture and no unexpected type conversion happen inside of it. The only conversion is from unsigned to signed type. char is left as a return type but treated as a signed type regradless of it's actual signedness. With the old version, int arguments were promoted to long and depending on architecture a long argument might result in s64 or long return type (which may or may not be the same). This came after some back and forth with Nicolas. The current macro has different return type (for the same input type) depending on architecture which might be midly iritating. An alternative version would promote to int like so: #define abs(x) __abs_choose_expr(x, long long, \ __abs_choose_expr(x, long, \ __builtin_choose_expr( \ sizeof(x) <= sizeof(int), \ ({ int __x = (x); __x<0?-__x:__x; }), \ ((void)0)))) I have no preference but imagine Linus might. :] Nicolas argument against is that promoting to int causes iconsistent behaviour: int main(void) { unsigned short a = 0, b = 1, c = a - b; unsigned short d = abs(a - b); unsigned short e = abs(c); printf("%u %u\n", d, e); // prints: 1 65535 } Then again, no sane person expects consistent behaviour from C integer arithmetic. ;) Note: __builtin_types_compatible_p(unsigned char, char) is always false, and __builtin_types_compatible_p(signed char, char) is also always false.

2016-01-14mac80211: pass block ack session timeout to to driverSara Sharon1-3/+6
Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session. Drivers that manage the reorder buffer need to know this parameter. Seeing that there are now too many arguments for the drv_ampdu_action() function, wrap them inside a structure.

2016-01-07iwlwifi: dvm: fix WoWLANEmmanuel Grumbach1-0/+3
My commit below introduced a mutex in the transport to prevent concurrent operations. To do so, it added a flag (is_down) to make sure the transport is in the right state. This uncoverred an bug that didn't cause any harm until now: iwldvm calls stop_device and then starts the firmware without calling start_hw in between. While this flow is fine from the device configuration point of view (register, etc...), it is now forbidden by the new is_down flag. This led to this error to appear: iwlwifi 0000:05:00.0: Can't start_fw since the HW hasn't been started and the suspend would fail.

802.11ac allows A-MSDU that can be up to 12KB long. Since an entire A-MSDU needs to fit into one single Receive Buffer (RB), add support for big RBs. Since this adds lots of pressure to the memory manager and significantly increase the true_size of the RX buffers, don't enable this by default. Signed-off-by: Emmanuel Grumbach <[email protected]>
