wlcore: change the wait for event mechanism · c45ee4ff

由 Yoni Divinsky 提交于 6月 27, 2012

wlcore needs to wait for certain events for example
for roc complete event. Usually the events are received
from the FW very fast, therefore wlcore can poll with
a short delay and if after a second the event was
not received yet poll with a long (1-5 msec) delay.

This implementation is similar to the sending of
commands to the FW.

Empirically the change reduced the wait for roc event
from ~10-40msec to 100s of usecs.

[replace udelay/msleep with usleep_range - Arik]

wlcore: Prevent processing of work items during op_stop · c24ec83b

由 Ido Yariv 提交于 6月 26, 2012

The interrupt line is disabled in op_stop using disable_irq. Since
pending interrupts are synchronized, the mutex has to be released before
disabling the interrupt to avoid a deadlock with the interrupt handler.

In addition, the internal state of the driver is only set to 'off'
after the interrupt is disabled. Otherwise, if an interrupt fires after
the state is set but before the interrupt line is disabled, the
interrupt handler will not be able to acknowledge the interrupt
resulting in an interrupt storm.

The driver's operations might be called during recovery. If these
acquire the mutex after it was released by op_stop, but before the
driver's state is changed, they may queue new work items instead of just
failing. This is especially problematic in the case of scans, in which a
new scan may be scheduled after all scan requests were cancelled.

wl12xx/wlcore: increase FW filename version · 66ef60ad

由 Luciano Coelho 提交于 6月 27, 2012

We have some API changes and new features in the new firmwares that
are not compatible with older drivers.  Increase the version of the FW
filenames for wl12xx to 5.

Additionally, remove the duplicate definitions from wlcore_i.h and
remove the MODULE_FIRMWARE macro calls from the SDIO and SPI modules,
since they're irrelevant there.

wlcore: add probe request templates for sched and one-shot scans · 3df74f46

由 Yoni Divinsky 提交于 6月 27, 2012

The driver configures the firmware template for probe requests during
the scan process.  If the same template is used for one-shot and sched
scans they will override each other when running scans simultaneously.

This fix works only on firmwares later than X.3.9.2.112 for single
role and X.3.9.2.23 for multi-role.

[Some cleaning-up and renaming of the quirk to something smaller --
