This patch series adds support for herolte (Samsung Galaxy S7) devices
to libsamsung-ipc.
CURRENT STATUS:
- the modem boots successfully
- it WILL NOT interact with userland unless something opens
/dev/umts_rfs0 at the same time as /dev/umts_ipc0 is open (see uses
of "rild_ready()" in the kernel source code)
- one way to get by for now is to repeatedly `cat /dev/umts_rfs0
>/dev/null` in another terminal
- once it starts talking, things look great until, running
`ipc-modem --debug start`, we soon get into the following tightish
loop:
...
[D] xmm626_kernel_smdk4412_fmt_recv: Message: aseq=0x00,
command=IPC_SMS_DEVICE_READY, type=IPC_TYPE_NOTI, size=1
[5] Modem is fully ready
[D] xmm626_kernel_smdk4412_fmt_send: Message: mseq=0xb6,
command=IPC_SMS_DEVICE_READY, type=IPC_TYPE_SET, size=0
[D] xmm626_kernel_smdk4412_fmt_recv: Message: aseq=0x00,
command=IPC_SMS_MEM_STATUS, type=IPC_TYPE_NOTI, size=2
[D] xmm626_kernel_smdk4412_fmt_recv: Message: aseq=0xb6,
command=IPC_GEN_PHONE_RES, type=IPC_TYPE_RESP, size=5
...
- it looks to me like each SET is triggering another NOTI. I haven't
investigated too far; it could be a bug in libsamsung-ipc, a bug in
ipc-modem, or a bug in my understanding of the situation!
OPEN QUESTIONS:
1. What should be done about the phone's need for /dev/umts_rfs0 to
be open at the same time as /dev/umts_ipc0 is open?
2. What's going on with that IPC_SMS_DEVICE_READY loop?
Regards,
Tony
