[PATCH 0/3] [PATCH 0/3] Documentation: virtual: convert files from .txt to

[Luke Nowakowski-Krijger]

From: Luke Nowakowski-Krijger <lnowakow@eng.ucsd.edu>

Converted a few documents in virtual and virtual/kvm to .rst format.
Also added toctree hooks wherever there were .rst files. Adding hooks to
the main doc tree should be in another patch series once there are more
files in the directory. 

After confirming with the appropriate lists that all the 
Documentation/virtual/* files are not obsolete I will continue
converting the rest of the .txt files to .rst.

[PATCH 1/3] Documentation: virtual: Add toctree hooks

[Luke Nowakowski-Krijger]

From: Luke Nowakowski-Krijger <lnowakow@eng.ucsd.edu>

Added toctree hooks for indexing. Hooks added only for newly added files
or already existing files. 

The hook for the top of the tree will be added in a later patch series
when a few more substantial changes have been added.

At this point in the patch series, the above-mentioned RST files don't
exist.  So if somebody tries to build the docs here, the build will fail.
I suspect that it's pretty rare for people to use bisection with docs
builds, but it's still proper practice to ensure that things work at every
step in your series.  So the above entries should be added in the patches
that convert the files.

Also, vcpu-requests.txt is never touched in this patch series, which
suggests that you didn't build the docs even at the end of it.

Thanks,

jon

Yes, agreed. It should be at the end of the series.

In the staging tree I was doing work out of I saw a vcpu-requests.rst
file so thought I could add it "while I'm here". 

You're right. I should only add the files I am converting.

[PATCH 2/3] Documentation: kvm: Convert cpuid.txt to .rst

[Luke Nowakowski-Krijger]

From: Luke Nowakowski-Krijger <lnowakow@eng.ucsd.edu>

Convert cpuid.txt to .rst format to be parsable by sphinx. 

Change format and spacing to make function definitions and return values
much more clear. Also added a table that is parsable by sphinx and makes
the information much more clean.

+
+A guest running on a kvm host, can check some of its features using
+cpuid. This is not always guaranteed to work, since userspace can
+mask-out some, or even all KVM-related cpuid features before launching
+a guest.
+
+KVM cpuid functions are:
+
+function: **KVM_CPUID_SIGNATURE (0x40000000)**
+
+returns::
+ 
+   eax = 0x40000001
+   ebx = 0x4b4d564b
+   ecx = 0x564b4d56
+   edx = 0x4d
+
+Note that this value in ebx, ecx and edx corresponds to the string "KVMKVMKVM".
+The value in eax corresponds to the maximum cpuid function present in this leaf,
+and will be updated if more functions are added in the future.
+Note also that old hosts set eax value to 0x0. This should
+be interpreted as if the value was 0x40000001.
+This function queries the presence of KVM cpuid leafs.

Do you know that this is the appropriate license for this file?  If so, you
should say how you know that.  I appreciate that you thought to add the
SPDX line, but we have to be sure that it actually matches the intent of
the creator of this file.

I wouldn't add the **markup** here, it doesn't really help.

You might consider using the

here, it might be a bit easier to read and maintain.

I do not know what the authors intent was. You are right. This is not my
work after all. Ill remove it in the next version.

No I guess it wont :). We would still keep this correct?

My intent was to make the "function" part more readable immediately
because otherwise it sort of looks like a wall of text. I might have
gotten a little too fancy here though.

There's nothing good that will come from keeping a broken email address
there.  You could either:

 - Just take the address out, or

 - Track Glauber down and get a newer address; you could ask him about the
   licensing while you're at it :)

I agree with this, there have been more authors since 2010.

Regarding the license, it was my understanding that if somebody wants
anything but GPL-2.0 they should put it in the file when they create it.
 That's because even if Glauber had a different idea of what license to
use, other contributors to the file couldn't know.

[PATCH 3/3] Documentation: virtual: Convert paravirt_ops.txt to .rst

[Luke Nowakowski-Krijger]

From: Luke Nowakowski-Krijger <lnowakow@eng.ucsd.edu>

Convert paravirt_opts.txt to .rst format to be able to be parsed by
sphinx. 

Made some minor spacing and formatting corrections to make defintions
much more clear and easy to read.
