11 years agoadd ability to read source files from git
Johannes Berg [Tue, 2 Apr 2013 19:08:35 +0000 (21:08 +0200)]
add ability to read source files from git

Instead of having to have a checked-out kernel tree the
script can now read the files from a git revision when
passed the --git-revision <rev> argument. In this case
the kerneldir is taken as the git tree to use.

This helps when generating for multiple different trees.

Note that due to the need to invoke git many times this
is considerably slower than copying from a checkout. If
taking into account the time to create the checkout it's
still faster though.

compat: backport fb_info->skip_vt_switch using a static inline

Commit 3cf2667 as of next-20130301 extended the struct fb_info
with a skip_vt_switch to allow drivers to skip the VT switch
at suspend/resume time. For older kernels we can skip this
as all this switch does is call pm_vt_switch_required() with true
or false depending on this new flag and later
pm_vt_switch_unregister() would not have been made.

compat-drivers was backporting this using #ifdef's but by
integrating a static inline we'd reduce the number of lines
to backport to just 1 line replacement. This would be something
like:

  -       info->skip_vt_switch = true;
  +       fb_enable_skip_vt_switch(info);

For kernels >= 3.10 we'd set the attribute as we do upstream,
for older kernels this would be a no-op.

If this static inline would have been added upstream it would
have meant this collateral evolution would require just adding
a no-op static inline to backport, and no changes as the above
example hunk for every driver that requires the change.

If this static inline ends up upstream *now* it means we do *not*
require the type of hunk above for every driver that requires
the change.

All the code would be left intact !

This is a linux-next 'data structure element collateral evolution'.

This patch cannot be broken down further so I'm pegging
this as the first one with 4 digits under the DRM folder
for collateral evolutions. This reflects its as atomic as
is possible. As we'll see on the next commit, these type
of collateral evolutions can best be backported not by
keeping ifdef's as below but instead by using a wrapper
caller, to help reduce with the amount of lines of code
we need. If a static inline is added upstream for these
changes, then no code is required for backporting, at all,
we'd just implement the static inline later upstream as
a no-op.

The tradeoffs to consider for this is if we can live with
these practices upstream, we may be able to support full
subsystems only with a compat module, and no need for
patches. This also means less code and likely less bugs
on the distribution front when backporting is required.
At least IMHO this may be worthy to consider at least to
support kernels listed as supported on kernel.org. We could
just leave the ifdef hell to older unsupported kernels.

    pages, similarly to other IO memory regions, setting only the DMA
    address for these. It does this, so that it can program the HW MMU
    tables in a uniform way both for sg lists with and without backing pages.

    Without a valid page pointer we can't call nth_page to get the current
    page in __sg_page_iter_next, so add a helper that relevant users can
    call separately. Also add a helper to get the DMA address of the current
    page (idea from Daniel).
