Revision 744c67ffeb06f2d2493f4049ba0bd19698ce0adf authored by Hui Wang on 19 March 2019, 01:28:43 UTC, committed by Takashi Iwai on 19 March 2019, 05:52:19 UTC
The commit 3baffc4a84d7 (ALSA: hda/intel: Refactoring PM code) changed the behaviour of azx_resume(), it triggers the jackpoll_work after applying this commit. This change introduced a new issue, all codecs are runtime active after S3, and will not call runtime_suspend() automatically. The root cause is the jackpoll_work calls snd_hda_power_up/down_pm, and it calls up_pm before snd_hdac_enter_pm is called, while calls the down_pm in the middle of enter_pm and leave_pm is called. This makes the dev->power.usage_count unbalanced after S3. To fix it, let azx_resume() don't trigger jackpoll_work as before it did.

select IRQ_POLL
---help---
Core support for InfiniBand (IB). Make sure to also select
any protocols you wish to use as well as drivers for your
InfiniBand hardware.

config INFINIBAND_USER_MAD
tristate "InfiniBand userspace MAD support"
depends on INFINIBAND
---help---
Userspace InfiniBand Management Datagram (MAD) support. This
is the kernel side of the userspace MAD support, which allows
userspace processes to send and receive MADs. You will also
need libibumad from rdma-core
<https://github.com/linux-rdma/rdma-core>.
config INFINIBAND_USER_ACCESS
tristate "InfiniBand userspace access (verbs and CM)"
select ANON_INODES
depends on MMU
---help---
Userspace InfiniBand access support. This enables the
kernel side of userspace verbs and the userspace
communication manager (CM). This allows userspace processes
to set up connections and directly access InfiniBand
hardware for fast-path operations. You will also need
libibverbs, libibcm and a hardware driver library from
rdma-core <https://github.com/linux-rdma/rdma-core>.
config INFINIBAND_USER_ACCESS_UCM
tristate "Userspace CM (UCM, DEPRECATED)"
depends on BROKEN || COMPILE_TEST
depends on INFINIBAND_USER_ACCESS
help
The UCM module has known security flaws, which no one is
interested to fix. The user-space part of this code was
dropped from the upstream a long time ago.
This option is DEPRECATED and planned to be removed.
config INFINIBAND_EXP_LEGACY_VERBS_NEW_UAPI
bool "Allow experimental legacy verbs in new ioctl uAPI (EXPERIMENTAL)"
depends on INFINIBAND_USER_ACCESS
---help---
IOCTL based uAPI support for Infiniband is enabled by default for
new verbs only. This allows userspace to invoke the IOCTL based uAPI
for current legacy verbs too.
config INFINIBAND_USER_MEM

depends on INFINIBAND_USER_ACCESS != n
depends on MMU
default y
config INFINIBAND_ON_DEMAND_PAGING
bool "InfiniBand on-demand paging support"
depends on INFINIBAND_USER_MEM
select MMU_NOTIFIER
default y
---help---
On demand paging support for the InfiniBand subsystem.
Together with driver support this allows registration of
memory regions without pinning their pages, fetching the
pages on demand instead.
config INFINIBAND_ADDR_TRANS
bool "RDMA/CM"
depends on INFINIBAND
default y
---help---
Support for RDMA communication manager (CM).
This allows for a generic connection abstraction over RDMA.
config INFINIBAND_ADDR_TRANS_CONFIGFS
bool
depends on INFINIBAND_ADDR_TRANS && CONFIGFS_FS && !(INFINIBAND=y && CONFIGFS_FS=m)
default y
---help---
ConfigFS support for RDMA communication manager (CM).
This allows the user to config the default GID type that the CM
uses for each device, when initiaing new connections.
