| 2 | README for btmrvl driver | |
| 3 | ======================================================================= | |
| 4 | ||
| 5 | ||
| 6 | All commands are used via debugfs interface. | |
| 7 | ||
| 8 | ===================== | |
| 9 | Set/get driver configurations: | |
| 10 | ||
| 11 | Path: /debug/btmrvl/config/ | |
| 12 | ||
| 13 | gpiogap=[n] | |
| 14 | hscfgcmd | |
| 15 | These commands are used to configure the host sleep parameters. | |
| 16 | bit 8:0 -- Gap | |
| 17 | bit 16:8 -- GPIO | |
| 18 | ||
| 19 | where GPIO is the pin number of GPIO used to wake up the host. | |
| 20 | It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface | |
| 21 | wakeup will be used instead). | |
| 22 | ||
| 23 | where Gap is the gap in milli seconds between wakeup signal and | |
| 24 | wakeup event, or 0xff for special host sleep setting. | |
| 25 | ||
| 26 | Usage: | |
| 27 | # Use SDIO interface to wake up the host and set GAP to 0x80: | |
| 28 | echo 0xff80 > /debug/btmrvl/config/gpiogap | |
| 29 | echo 1 > /debug/btmrvl/config/hscfgcmd | |
| 30 | ||
| 31 | # Use GPIO pin #3 to wake up the host and set GAP to 0xff: | |
| 32 | echo 0x03ff > /debug/btmrvl/config/gpiogap | |
| 33 | echo 1 > /debug/btmrvl/config/hscfgcmd | |
| 34 | ||
| 35 | psmode=[n] | |
| 36 | pscmd | |
| 37 | These commands are used to enable/disable auto sleep mode | |
| 38 | ||
| 39 | where the option is: | |
| 40 | 1 -- Enable auto sleep mode | |
| 41 | 0 -- Disable auto sleep mode | |
| 42 | ||
| 43 | Usage: | |
| 44 | # Enable auto sleep mode | |
| 45 | echo 1 > /debug/btmrvl/config/psmode | |
| 46 | echo 1 > /debug/btmrvl/config/pscmd | |
| 47 | ||
| 48 | # Disable auto sleep mode | |
| 49 | echo 0 > /debug/btmrvl/config/psmode | |
| 50 | echo 1 > /debug/btmrvl/config/pscmd | |
| 51 | ||
| 52 | ||
| 53 | hsmode=[n] | |
| 54 | hscmd | |
| 55 | These commands are used to enable host sleep or wake up firmware | |
| 56 | ||
| 57 | where the option is: | |
| 58 | 1 -- Enable host sleep | |
| 59 | 0 -- Wake up firmware | |
| 60 | ||
| 61 | Usage: | |
| 62 | # Enable host sleep | |
| 63 | echo 1 > /debug/btmrvl/config/hsmode | |
| 64 | echo 1 > /debug/btmrvl/config/hscmd | |
| 65 | ||
| 66 | # Wake up firmware | |
| 67 | echo 0 > /debug/btmrvl/config/hsmode | |
| 68 | echo 1 > /debug/btmrvl/config/hscmd | |
| 69 | ||
| 70 | ||
| 71 | ====================== | |
| 72 | Get driver status: | |
| 73 | ||
| 74 | Path: /debug/btmrvl/status/ | |
| 75 | ||
| 76 | Usage: | |
| 77 | cat /debug/btmrvl/status/<args> | |
| 78 | ||
| 79 | where the args are: | |
| 80 | ||
| 81 | curpsmode | |
| 82 | This command displays current auto sleep status. | |
| 83 | ||
| 84 | psstate | |
| 85 | This command display the power save state. | |
| 86 | ||
| 87 | hsstate | |
| 88 | This command display the host sleep state. | |
| 89 | ||
| 90 | txdnldrdy | |
| 91 | This command displays the value of Tx download ready flag. | |
| 92 | ||
| 93 | ||
| 94 | ===================== | |
| 95 | ||
| 96 | Use hcitool to issue raw hci command, refer to hcitool manual | |
| 97 | ||
| 98 | Usage: Hcitool cmd <ogf> <ocf> [Parameters] | |
| 99 | ||
| 100 | Interface Control Command | |
| 101 | hcitool cmd 0x3f 0x5b 0xf5 0x01 0x00 --Enable All interface | |
| 102 | hcitool cmd 0x3f 0x5b 0xf5 0x01 0x01 --Enable Wlan interface | |
| 103 | hcitool cmd 0x3f 0x5b 0xf5 0x01 0x02 --Enable BT interface | |
| 104 | hcitool cmd 0x3f 0x5b 0xf5 0x00 0x00 --Disable All interface | |
| 105 | hcitool cmd 0x3f 0x5b 0xf5 0x00 0x01 --Disable Wlan interface | |
| 106 | hcitool cmd 0x3f 0x5b 0xf5 0x00 0x02 --Disable BT interface | |
