There is quite a bit of overlap between this patch and our patch series
(https://lkml.org/lkml/2016/2/5/544)
There are few things I see missing in this patch in your updates made to
actbl1.h, I list them below:
1) Adding time stamp as you did breaks backwards compatibility
(something we discovered during our testing). We tried to remedy this
by adding a new version of the acpi_hest_generic_data structure. Note
that we named it v3 to reflect this was the updated version number in
ACPI 6.1. (see https://lkml.org/lkml/2016/2/5/549)
2) Missing definition of generic error data validation bits, needed to
determine whether or not field being read are valid or not (see
https://lkml.org/lkml/2016/2/5/549)
3) Need to extend acpi_hest_notify_types to add GPIO, SEA, SEI, and GSIV
(see https://lkml.org/lkml/2016/2/5/545)
4) Also for the purpose of backwards compatibility, we needed to add
both acpi_hest_generic and acpi_hest_generic_v2 to the structure "ghes",
referencing the v2 pointer when needed. (https://lkml.org/lkml/2016/2/5/550)
Can you please review the above patch series patches for comparison, and
if in agreement, can you please update this patch to better align with
the changes we need? We can rework our patch series to depend on your
patch series (i.e. leaving actbl1.h untouched on our side).
