How do I gather up new code to be converted as patches?

[Kevin Brace]

Hi Sam,

Okay, I think what you proposed works out for me, although adding 20+ files, one by one, is a pain.
I wish there is a way to automate this.
FWIW, this is how I did it.

________
1) Create a new branch from the current one just for sending the patches

$ git branch Code_Review_1

2) Switch to the new branch

$ git checkout Code_Review_1

3) Copy original drivers/gpu/drm/via/ contents (i.e., *.c, *.h, Kconfig, and Makefile) and include/uapi/drm/via_drm.h
4) Delete drivers/gpu/drm/via/ contents and include/uapi/drm/via_drm.h
5) Delete from DRM core make file (Makefile) located at drivers/gpu/drm/ its OpenChrome DRM build switch

. . .
obj-$(CONFIG_DRM_OPENCHROME) +=via/
. . .

6) Commit the change (Note: this commit will not be posted as a patch)

$ git commit -as

7) Move back the preserved files to drivers/gpu/drm/via/ (i.e., *.c, *.h, Kconfig, Makefile) and include/uapi/drm/ (i.e., via_drm.h)
8) Add and commit *.h located at drivers/gpu/drm/via/ one file at a time

$ git add drivers/gpu/drm/via/("Name of the file").h
$ git commit -as

9) Add and commit *.c located at drivers/gpu/drm/via/ one file at a time

$ git add drivers/gpu/drm/via/("Name of the file").c
$ git commit -as

10) Add and commit via_drm.h located at include/uapi/drm/

$ git add include/uapi/drm/via_drm.h
$ git commit -as

11) Commit Kconfig located at drivers/gpu/drm/via/

$ git add drivers/gpu/drm/via/Kconfig
$ git commit -as

12) Commit Makefile located at drivers/gpu/drm/via/

$ git add drivers/gpu/drm/via/Makefile
$ git commit -as

13) Add back to DRM core make file (Makefile) located at drivers/gpu/drm/ the OpenChrome DRM build switch

. . .
obj-$(CONFIG_DRM_OPENCHROME) +=via/
. . .

14) Commit the change

$ git commit -as

15) Generate the commits as patches

$ git format-patch -28

The (-28) may be adjusted to match the number of relevant commits.
It is basically derived from,

- 26 files under drivers/gpu/drm/via/
- 1 file under include/uapi/drm/
- 1 commit to change Makefile located at drivers/gpu/drm/

The first commit that deletes the relevant files should not be included in the patch being generated here.
________

I wish there is a easier, more automated way of doing this, but at least this is the best I can do for now.
I will likely e-mail the mailing list the code in patch form shortly.
