Revision 4a133eb351ccc275683ad49305d0b04dde903733 authored by Christophe Leroy on 27 August 2020, 18:30:27 UTC, committed by Michael Ellerman on 28 August 2020, 02:03:18 UTC
low_sleep_handler() can't restore the context from virtual stack because the stack can hardly be accessed with MMU OFF. For now, disable VMAP stack when CONFIG_ADB_PMU is selected.

config QRTR
tristate "Qualcomm IPC Router support"
help
Say Y if you intend to use Qualcomm IPC router protocol. The
protocol is used to communicate with services provided by other
hardware blocks in the system.
In order to do service lookups, a userspace daemon is required to
maintain a service listing.
if QRTR
config QRTR_SMD
tristate "SMD IPC Router channels"
depends on RPMSG || (COMPILE_TEST && RPMSG=n)
help
Say Y here to support SMD based ipcrouter channels. SMD is the
most common transport for IPC Router.
config QRTR_TUN
tristate "TUN device for Qualcomm IPC Router"
help
Say Y here to expose a character device that allows user space to
implement endpoints of QRTR, for purpose of tunneling data to other
hosts or testing purposes.
config QRTR_MHI
tristate "MHI IPC Router channels"
depends on MHI_BUS
help
Say Y here to support MHI based ipcrouter channels. MHI is the
transport used for communicating to external modems.
