Hello,
Changes since v3:
- pwm-twl-led driver's comment fix patch squashed to the original patch
- Documentation for the DT bindings of the PWM drivers
Comments from Thierry Reding addressed:
- pwm-twl6030 has been removed in the last patch
- macro for twl_pwm_chip/twl_pwmled_chip lookup
-
The driver supports the following LED outputs as generic PWM driver:
TWL4030 LEDA and LEDB (PWMA and PWMB)
TWL6030 Charging indicator LED (PWM LED)
On TWL6030 when the PWM requested LED is configured to be controlled by SW.
In this case the user can enable/disable and set the duty period freely.
The driver supports the following PWM outputs:
TWL4030 PWM0 and PWM1
TWL6030 PWM1 and PWM2
On TWL4030 the PWM signals are muxed. Upon requesting the PWM the driver
will select the correct mux so the PWM can be used. When the PWM has been
freed the original configuration is going to be restored.
This function allows to obtain a per-cpu variable, either of the current
or an explicitly specified CPU.

This is a shorthand for *$lx_per_cpu(current_task), i.e. a convenience
function to retrieve the currently running task of the active context.

This helper probes the type of the gdb server. Supported are QEMU and
KGDB so far. Knowledge about the gdb server is required e.g. to retrieve
the current CPU or current task.

Add the internal helper get_thread_info that calculated the thread_info
from a given task variable. Also export this service as a convenience
function.
Note: ia64 version is untested.

Parse the target endianness from the output of show endian and cache
the result to return it via the new helper get_target_endiannes. We will
need it for reading integers from buffers that contain target memory.

The internal helper for_each_task iterates over all tasks of the target,
calling the provided function on each. For performance reasons, we cache
a reference to the gdb type object of a task.

Add the helper task_by_pid that can look up a task by its PID. Also
export it as a convenience function.

This is probably the most useful helper when debugging kernel modules:
lx-symbols will first reload vmlinux. Then it searches recursively for
*.ko files in the specified paths and the current directory. Finally it
walks the kernel's module list, issuing the necessary add-symbol-file
command for
This pokes into the log buffer of the debugged kernel, dumping it to the
gdb console. Helping in case the target should or can no longer execute
dmesg itself.

Add helpers for reading integers from target memory buffers. Required
when caching the memory access is more efficient than reading individual
values via gdb.

Hi all:
This series is an update version of multiqueue virtio-net driver based on
Krishna Kumar's work to let virtio-net use multiple rx/tx queues to do the
packets reception and transmission. Please review and comments.

To support multiqueue transmitq/receiveq, the first step is to separate queue
related structure from virtnet_info. This patch introduce send_queue and
receive_queue structure and use the pointer to them as the parameter in
functions handling sending/receiving.

This addes multiqueue support to virtio_net driver. In multiple queue modes, the
driver expects the number of queue paris is equal to the number of vcpus. To
eliminate the contention bettwen vcpus and virtqueues, per-cpu virtqueue pairs
were implemented through:
