Hi,
Here is updated version (v.3) of patches for ASPM.
The major purposes of this set of patches are:
- Supporting partial ASPM enablement
- Supporting per direction L0s management.
ChangeLog:
[v.2 -> v.3]
- Fixed a bug that might cause infinit loop (feedback from Li Shaohua)
- Changed partial ASPM enablement to enable L0s only when L0s is
supported in both upstream compornent and downstream component of
the link (feedback from Li Shaohua).
[v.1 -> v.2]
- Separated a patch into smaller pieces (seven patches).
- Fixed a bug that default ASPM state is not saved.
- Fixed comment typo in pcie_aspm_cap_init().
- Added 'break;' to list_for_each_entry() loop to avoid redundant
loop in pcie_aspm_cap_init().
- Removed pcie_aspm_check_latency() function prototype by changing
the location of pcie_aspm_check_latency() was changed.
The patches are:
- [PATCH 1/7] PCI ASPM: do not clear enabled field by support field
- [PATCH 2/7] PCI ASPM: remove redundant list check
- [PATCH 3/7] PCI ASPM: fix possible null pointer dereference
- [PATCH 4/7] PCI ASPM: introduce disable flag
- [PATCH 5/7] PCI ASPM: introduce capable flag
- [PATCH 6/7] PCI ASPM: support partial aspm enablement
- [PATCH 7/7] PCI ASPM: support per direction l0s management
Thanks,
Kenji Kaneshige
