btmrvl driver |
|
============= |
|
|
|
All commands are used via debugfs interface. |
|
|
|
Set/get driver configurations |
|
============================= |
|
|
|
Path: /debug/btmrvl/config/ |
|
|
|
gpiogap=[n], hscfgcmd |
|
These commands are used to configure the host sleep parameters:: |
|
bit 8:0 -- Gap |
|
bit 16:8 -- GPIO |
|
|
|
where GPIO is the pin number of GPIO used to wake up the host. |
|
It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface |
|
wakeup will be used instead). |
|
|
|
where Gap is the gap in milli seconds between wakeup signal and |
|
wakeup event, or 0xff for special host sleep setting. |
|
|
|
Usage:: |
|
|
|
# Use SDIO interface to wake up the host and set GAP to 0x80: |
|
echo 0xff80 > /debug/btmrvl/config/gpiogap |
|
echo 1 > /debug/btmrvl/config/hscfgcmd |
|
|
|
# Use GPIO pin #3 to wake up the host and set GAP to 0xff: |
|
echo 0x03ff > /debug/btmrvl/config/gpiogap |
|
echo 1 > /debug/btmrvl/config/hscfgcmd |
|
|
|
psmode=[n], pscmd |
|
These commands are used to enable/disable auto sleep mode |
|
|
|
where the option is:: |
|
|
|
1 -- Enable auto sleep mode |
|
0 -- Disable auto sleep mode |
|
|
|
Usage:: |
|
|
|
# Enable auto sleep mode |
|
echo 1 > /debug/btmrvl/config/psmode |
|
echo 1 > /debug/btmrvl/config/pscmd |
|
|
|
# Disable auto sleep mode |
|
echo 0 > /debug/btmrvl/config/psmode |
|
echo 1 > /debug/btmrvl/config/pscmd |
|
|
|
|
|
hsmode=[n], hscmd |
|
These commands are used to enable host sleep or wake up firmware |
|
|
|
where the option is:: |
|
|
|
1 -- Enable host sleep |
|
0 -- Wake up firmware |
|
|
|
Usage:: |
|
|
|
# Enable host sleep |
|
echo 1 > /debug/btmrvl/config/hsmode |
|
echo 1 > /debug/btmrvl/config/hscmd |
|
|
|
# Wake up firmware |
|
echo 0 > /debug/btmrvl/config/hsmode |
|
echo 1 > /debug/btmrvl/config/hscmd |

Get driver status |
|
================= |
|
|
|
Path: /debug/btmrvl/status/ |
|
|
|
Usage:: |
|
|
|
cat /debug/btmrvl/status/<args> |
|
|
|
where the args are: |
|
|
|
curpsmode |
|
This command displays current auto sleep status. |
|
|
|
psstate |
|
This command display the power save state. |
|
|
|
hsstate |
|
This command display the host sleep state. |
|
|
|
txdnldrdy |
|
This command displays the value of Tx download ready flag. |
|
|
|
Issuing a raw hci command |
|
========================= |
|
|
|
Use hcitool to issue raw hci command, refer to hcitool manual |
|
|
|
Usage:: |
|
|
|
Hcitool cmd <ogf> <ocf> [Parameters] |
|
|
|
Interface Control Command:: |
|
|
|
hcitool cmd 0x3f 0x5b 0xf5 0x01 0x00 --Enable All interface |
|
hcitool cmd 0x3f 0x5b 0xf5 0x01 0x01 --Enable Wlan interface |
|
hcitool cmd 0x3f 0x5b 0xf5 0x01 0x02 --Enable BT interface |
|
hcitool cmd 0x3f 0x5b 0xf5 0x00 0x00 --Disable All interface |
|
hcitool cmd 0x3f 0x5b 0xf5 0x00 0x01 --Disable Wlan interface |
|
hcitool cmd 0x3f 0x5b 0xf5 0x00 0x02 --Disable BT interface |
