are located, default /usr/src/linux.
1.1 Troubleshooting
~~~~~~~~~~~~~~~~~~~
Q: Module yealink compiled and installed without any problem but phone
is not initialized and does not react to any actions.
A: If you see something like:
hiddev0: USB HID v1.00 Device [Yealink Network Technology Ltd. VOIP USB Phone
in dmesg, it means that the hid driver has grabbed the device first. Try to
load module yealink before any other usb hid driver. Please see the
instructions provided by your distribution on module configuration.
Q: Phone is working now (displays version and accepts keypad input) but I can't
find the sysfs files.
A: The sysfs files are located on the particular usb endpoint. On most
distributions you can do: "find /sys/ -name get_icons" for a hint.

* Reserved Page provided by SAL.
* the reserved page
*
* SAL provides one page per partition of reserved memory. When SAL
* initialization is complete, SAL_signature, SAL_version, partid,
* part_nasids, and mach_nasids are set.
* SAL reserves one page of memory per partition for XPC. Though a full page
* in length (16384 bytes), its starting address is not page aligned, but it
* is cacheline aligned. The reserved page consists of the following:
*
* reserved page header
*
* The first cacheline of the reserved page contains the header
* (struct xpc_rsvd_page). Before SAL initialization has completed,
* SAL has set up the following fields of the reserved page header:
* SAL_signature, SAL_version, partid, and nasids_size. The other
* fields are set up by XPC. (xpc_rsvd_page points to the local
* partition's reserved page.)
*
* part_nasids mask
* mach_nasids mask
*
* SAL also sets up two bitmaps (or masks), one that reflects the actual
* nasids in this partition (part_nasids), and the other that reflects
* the actual nasids in the entire machine (mach_nasids). We're only
* interested in the even numbered nasids (which contain the processors
* and/or memory), so we only need half as many bits to represent the
* nasids. The part_nasids mask is located starting at the first cacheline
* following the reserved page header. The mach_nasids mask follows right
* after the part_nasids mask. The size in bytes of each mask is reflected
* by the reserved page header field 'nasids_size'. (Local partition's
* mask pointers are xpc_part_nasids and xpc_mach_nasids.)
*
* vars
* vars part
*
* Immediately following the mach_nasids mask are the XPC variables
* required by other partitions. First are those that are generic to all
* partitions (vars), followed on the next available cacheline by those
* which are partition specific (vars part). These are setup by XPC.
* (Local partition's vars pointers are xpc_vars and xpc_vars_part.)
*
* Note: Until vars_pa is set, the partition XPC code has not been initialized.

If you say Y here, you can use driver calls or the sysfs

remote wakeup and driver-specific suspend processing, that

Also, USB "remote wakeup" signaling is supported, whereby some
USB devices (like keyboards and network adapters) can wake up
their parent hub. That wakeup cascades up the USB tree, and
could wake the system from states like suspend-to-RAM.
