aubtfwl -- Atheros AR3011 Firmware Loader SYNOPSIS
aubtfwl* at uhub? DESCRIPTION
The aubtfwl driver manages automatic loading of firmware on the Atheros AR3011 Bluetooth chipset. The firmware file ath3k-1.fw should be obtained and placed in a ubt/ directory in the search path of the firmload(9) kernel subsystem. Upon attachment, the aubtfwl driver will load this firmware file and the device will detach and reattach as a generic Bluetooth device using the ubt(4) driver. The firmware file can be obtained from the Linux firmware git repository at FILES

firmload -- Firmware loader API for device drivers SYNOPSIS
#include <dev/firmload.h> int firmware_open(const char *drvname, const char *imgname, firmware_handle_t *fhp); int firmware_close(firmware_handle_t fh); off_t firmware_get_size(firmware_handle_t fh); int firmware_read(firmware_handle_t fh, off_t offset, void *buf, size_t size); void * firmware_malloc(size_t size); void firmware_free(void *buf, size_t size); DESCRIPTION
firmload provides a simple and convenient API for device drivers to load firmware images from files residing in the file system that are nec- essary for the devices that they control. Firmware images reside in sub-directories, one for each driver, of a series of colon-separated path prefixes specified by the sysctl variable hw.firmware.path. FUNCTIONS
The following functions are provided by the firmload API: firmware_open(drvname, imgname, fhp) Open then firmware image imgname for the driver drvname. The path to the firmware image file is constructed by appending the string ``/drvname/imgname'' to each configured path prefix until opening the firmware image file succeeds. Upon success, firmware_open() returns 0 and stores a firmware image handle in the location pointed to by fhp. Otherwise, an error code is returned to indicate the reason for failure. firmware_close(fh) Close the firmware image file associated with the firmware handle fh. Returns 0 upon success or an error code to indicate the reason for failure. firmware_get_size(fh) Returns the size of the image file associated with the firmware handle fh. firmware_read(fh, offset, buf, size) Reads from the image file associated with the firmware handle fh beginning at offset offset for length size. The firmware image data is placed into the buffer specified by buf. Returns 0 upon success or an error code to indicate the reason for failure. firmware_malloc(size) Allocates a region of wired kernel memory of size size. Note: firmware_malloc() may block. firmware_free(buf, size) Frees a region of memory previously allocated by firmware_malloc(). SEE ALSO
