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.

README for MIPS AU1XXX IDE driver - Released 2005-07-15
ABOUT
-----
This file describes the 'drivers/ide/mips/au1xxx-ide.c', related files and the
services they provide.
If you are short in patience and just want to know how to add your hard disc to
the white or black list, go to the 'ADD NEW HARD DISC TO WHITE OR BLACK LIST'
section.

FILES, CONFIGS AND COMPATABILITY
--------------------------------
Two files are introduced:
a) 'include/asm-mips/mach-au1x00/au1xxx_ide.h'
containes : struct _auide_hwif
struct drive_list_entry dma_white_list
struct drive_list_entry dma_black_list
timing parameters for PIO mode 0/1/2/3/4
timing parameters for MWDMA 0/1/2
b) 'drivers/ide/mips/au1xxx-ide.c'
contains the functionality of the AU1XXX IDE driver
Four configs variables are introduced:
CONFIG_BLK_DEV_IDE_AU1XXX_PIO_DBDMA - enable the PIO+DBDMA mode
CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA - enable the MWDMA mode
CONFIG_BLK_DEV_IDE_AU1XXX_BURSTABLE_ON - set Burstable FIFO in DBDMA
controler
CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ - maximum transfer size
per descriptor
If MWDMA is enabled and the connected hard disc is not on the white list, the
kernel switches to a "safe mwdma mode" at boot time. In this mode the IDE
performance is substantial slower then in full speed mwdma. In this case
please add your hard disc to the white list (follow instruction from 'ADD NEW
HARD DISC TO WHITE OR BLACK LIST' section).
SUPPORTED IDE MODES
-------------------
The AU1XXX IDE driver supported all PIO modes - PIO mode 0/1/2/3/4 - and all
MWDMA modes - MWDMA 0/1/2 -. There is no support for SWDMA and UDMA mode.
To change the PIO mode use the program hdparm with option -p, e.g.
'hdparm -p0 [device]' for PIO mode 0. To enable the MWDMA mode use the option
-X, e.g. 'hdparm -X32 [device]' for MWDMA mode 0.
PERFORMANCE CONFIGURATIONS
--------------------------
If the used system doesn't need USB support enable the following kernel configs:
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_IDE_GENERIC=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_GENERIC=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDE_AU1XXX=y
CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
CONFIG_BLK_DEV_IDE_AU1XXX_BURSTABLE_ON=y
CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ=128
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y
If the used system need the USB support enable the following kernel configs for
high IDE to USB throughput.
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDE_GENERIC=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_GENERIC=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDE_AU1XXX=y
CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ=128
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y
ADD NEW HARD DISC TO WHITE OR BLACK LIST
----------------------------------------
Step 1 : detect the model name of your hard disc
a) connect your hard disc to the AU1XXX
b) boot your kernel and get the hard disc model.
Example boot log:
--snipped--
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx
Au1xxx IDE(builtin) configured for MWDMA2
Probing IDE interface ide0...
hda: Maxtor 6E040L0, ATA DISK drive
ide0 at 0xac800000-0xac800007,0xac8001c0 on irq 64
hda: max request size: 64KiB
hda: 80293248 sectors (41110 MB) w/2048KiB Cache, CHS=65535/16/63, (U)DMA
--snipped--
In this example 'Maxtor 6E040L0'.
Step 2 : edit 'include/asm-mips/mach-au1x00/au1xxx_ide.h'
Add your hard disc to the dma_white_list or dma_black_list structur.
Step 3 : Recompile the kernel
Enable MWDMA support in the kernel configuration. Recompile the kernel and
reboot.
Step 4 : Tests
If you have add a hard disc to the white list, please run some stress tests
for verification.

These drivers wouldn't have been done without the base of kernel 2.4.x AU1XXX
IDE driver from AMD.

* 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.
