[PATCH v4 02/30] xen/riscv: use some asm-generic headers
Posted by Oleksii Kurochko 7 months ago 
Some headers are the same as asm-generic verions of them
so use them instead of arch-specific headers.

 As [PATCH v6 0/9] Introduce generic headers
 (https://lore.kernel.org/xen-devel/cover.1703072575.git.oleksii.kurochko@gmail.com/)
 is not stable, the list in asm/Makefile can be changed, but the changes will
 be easy.
---
Changes in V4:
- removed numa.h from asm/include/Makefile because of the patch: [PATCH v2] NUMA: no need for asm/numa.h when !NUMA
- updated the commit message
---
Changes in V3:
 - remove monitor.h from the RISC-V asm/Makefile list.
 - add Acked-by: Jan Beulich <jbeulich@suse.com>

Just to mention it (I'll commit this as is, unless asked to do otherwise):
With this description I'd expect those "some headers" to be removed by
this patch. Yet you're not talking about anything that exists; instead I
think you mean "would end up the same". Yet that's precisely what
asm-generic/ is for. Hence I would have said something along the lines of
"don't need any customization".

Or wait - doesn't this mean the change here can't be committed yet? I
know the cover letter specifies dependencies, yet I think we need to come
to a point where this large series won't need re-posting again and again.

Agree that "some headers" isn't the best one option to describe the
changes. Perhaps, it would be better to specify the headers which would
end up the same as asm-generic's version.
Thanks for such notes!

We can't committed it now because asm-generic version of device.h,
which is not commited yet.

We can drop the change " generic-y += device.h ", and commit the
current one patch, but it sill will require to create a new patch for
using of asm-generic/device.h. Or as an option, I can merge "generic-y
+= device.h" into PATCH 29/30 xen/riscv: enable full Xen build.

I don't expect that the of asm-generic headers will changed in
riscv/include/asm/Makefile, but it looks to me that it is better to
wait until asm-generic/device.h will be in staging branch.


If you have better ideas, please share it with me.

My main point was that the interdependencies here have grown too far,
imo. The more that while having dependencies stated in the cover letter
is useful, while committing (and also reviewing) I for one would
typically only look at the individual patches.

For this patch alone, maybe it would be more obvious that said
dependency exists if it was last on the asm-generic series, rather
than part of the series here (which depends on that other series
anyway). That series now looks to be making some progress, and it being
a prereq for here it may be prudent to focus on getting that one in,
before re-posting here.

I'll be more specific next time regarding dependencies and specify what
a prereq changes are.

Considering that asm-generic/device.h was merged to staging branch. It
seems to me that there are no more additional prereqs for this patch.
