[LTP] [PATCH v2] fw_load: new test of device firmware loading
|
From: Alexey K. <ale...@or...> - 2013-06-14 11:18:31
|
This test checks that from kernel 3.7 firmware can be loaded directly
(by-pass udev) or as usual. The test consists of the two parts: userspace
and kernelspace.

+The aim of the test is to check that after kernel 3.7 firmware can be loaded
+directly (by-pass udev) or as usual. The test consists of the two parts:
+ - userspace part
+ - kernelspace part
+
+This is a kernel module, which is a part of the device firmware loading test.
+It allows to call request_firmware kernel function with specified parameters.
+The parameters passed with the insmod command. They include template firmware
+file name, number of firmware files to request, and expected data size in the
+firmware files. In the end, the device will create sysfs file, that can be
+read to get request firmware results. Also, some information regarding module
+loading, can be obtained by looking at kernel log file.
+
+It is automatically used by user space part of the test.

+ - replace udev's searched paths to tmp directory (firmware.sh)
+ - load the module and wait for results
+ - read device's result file and print test results
+ - clean up tmp directory and unload the module.
