| 2 | btmrvl driver | |
| 3 | ============= | |
| 196be0cd BZ |
4 | |
| 5 | All commands are used via debugfs interface. | |

| 7f4e0121 MCC |
7 | Set/get driver configurations |
| 8 | ============================= | |

| 11 | ||
| 7f4e0121 MCC |
12 | gpiogap=[n], hscfgcmd |
| 13 | These commands are used to configure the host sleep parameters:: | |
| 196be0cd BZ |
14 | bit 8:0 -- Gap |
| 15 | bit 16:8 -- GPIO | |
| 16 | ||
| 17 | where GPIO is the pin number of GPIO used to wake up the host. | |
| 18 | It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface | |
| 19 | wakeup will be used instead). | |
| 20 | ||
| 21 | where Gap is the gap in milli seconds between wakeup signal and | |
| 22 | wakeup event, or 0xff for special host sleep setting. | |
| 23 | ||
| 7f4e0121 MCC |
24 | Usage:: |
| 25 | ||
| 196be0cd BZ |
26 | # Use SDIO interface to wake up the host and set GAP to 0x80: |
| 27 | echo 0xff80 > /debug/btmrvl/config/gpiogap | |
| 28 | echo 1 > /debug/btmrvl/config/hscfgcmd | |
| 29 | ||
| 30 | # Use GPIO pin #3 to wake up the host and set GAP to 0xff: | |
| 31 | echo 0x03ff > /debug/btmrvl/config/gpiogap | |
| 32 | echo 1 > /debug/btmrvl/config/hscfgcmd | |
| 33 | ||
| 7f4e0121 | 34 | psmode=[n], pscmd |
| 196be0cd BZ |
35 | These commands are used to enable/disable auto sleep mode |
| 36 | ||
| 7f4e0121 MCC |
37 | where the option is:: |
| 38 | ||
| 196be0cd BZ |
39 | 1 -- Enable auto sleep mode |
| 40 | 0 -- Disable auto sleep mode | |
| 41 | ||
| 7f4e0121 MCC |
42 | Usage:: |
| 43 | ||
| 196be0cd BZ |
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 | ||
| 7f4e0121 | 53 | hsmode=[n], hscmd |
| 196be0cd BZ |
54 | These commands are used to enable host sleep or wake up firmware |
| 55 | ||
| 7f4e0121 MCC |
56 | where the option is:: |
| 57 | ||
| 196be0cd BZ |
58 | 1 -- Enable host sleep |
| 59 | 0 -- Wake up firmware | |
| 60 | ||
| 7f4e0121 MCC |
61 | Usage:: |
| 62 | ||
| 196be0cd BZ |
63 | # Enable host sleep |
| 64 | echo 1 > /debug/btmrvl/config/hsmode | |
| 65 | echo 1 > /debug/btmrvl/config/hscmd | |
| 66 | ||
| 67 | # Wake up firmware | |
| 68 | echo 0 > /debug/btmrvl/config/hsmode | |
| 69 | echo 1 > /debug/btmrvl/config/hscmd | |

72 | Get driver status |
| 73 | ================= | |
| 196be0cd BZ |
74 | |
| 75 | Path: /debug/btmrvl/status/ | |
| 76 | ||
| 7f4e0121 MCC |
77 | Usage:: |
| 78 | ||
| 196be0cd BZ |
79 | cat /debug/btmrvl/status/<args> |
| 80 | ||
| 81 | where the args are: | |
| 82 | ||
| 83 | curpsmode | |
| 84 | This command displays current auto sleep status. | |
| 85 | ||
| 86 | psstate | |
| 87 | This command display the power save state. | |
| 88 | ||
| 89 | hsstate | |
| 90 | This command display the host sleep state. | |
| 91 | ||
| 92 | txdnldrdy | |
| 93 | This command displays the value of Tx download ready flag. | |
| 94 | ||

| 96 | ========================= | |
| 196be0cd BZ |
97 | |
| 98 | Use hcitool to issue raw hci command, refer to hcitool manual | |
| 99 | ||
| 7f4e0121 MCC |
