[PATCH 2/5] OvmfPkg/build.sh: Don't automatically -hda qemu parameter

[Jordan Justen]

This hasn't worked for me in quite some time. I always add a -cdrom
paramter, which causes build.sh to skip this.

[PATCH 3/5] OvmfPkg/build.sh: Move automatic TARGET_TOOLS detection later

[Jordan Justen]

If we are building for a non-native ARM, then we may need to select a
cross-compiler based on the -a paramter.

Re: [edk2-devel] [PATCH 1/5] OvmfPkg/build.sh: Require QEMU 1.6 or newer and always enable flash

[Laszlo Ersek]

Hi Jordan,

I've asked Phil (CC'd) to review this series in my stead. I'll be happy
to provide an ACK when Phil gives his R-b (if I should forget, please
ping me separately).

In the future, please include a cover letter; a cumulative diffstat
usually helps with the review. (I've had to check all patches to see
that only build.sh is being modified.)

Thanks,
Laszlo

I am sorry but I am non-native English and I have hard time to
understand your comment.

OVMF targets x86 hardware, which is obviously not ARM. And I'm not aware
of another target architecture.  Are you talking about the host where
you build?

I am trying your series on a Aarch64 host but I fail at passing the
correct cross gcc. I set GCC5_IA32_PREFIX, GCC5_X64_PREFIX and GCC5_BIN
env vars, but the build script still run '"gcc"' instead of my cross one.

A more generic comment regarding your series: how do you use this script?

Thanks,

Phil.

This doesn't appear to indicate any particular architecture or VMM.
Nevertheless, ArmVirtPkg was created, so in effect, you are correct.

I mean the target. The patch looks for something like "-a AARCH64" on
the command line. If found, we try to build ArmVirtPkg/ArmVirtQemu.dsc
instead of OVMF.

It's a bit of a hack in that it will try to build the dsc from another
package. But, OvmfPkg/build.sh is a little more generic than one might
expect. For example, when I want to build MdeModulePkg, I usually just
run:

OvmfPkg/build.sh -p MdeModulePkg/MdeModulePkg.dsc

I find it convenient that the script sets up the build environment
automatically, and after the script is done, no changes persist in my
shell's environment.

Yeah, you are right. The comments could be better. I'll try to improve
them.

Basically, these changes let me build ArmVirtPkg/ArmVirtQemu.dsc on
x86_64 Linux by simply added "-a AARCH64" or "-a ARM" parameteres to
this script. It also helped setup the qemu command line. Here are the
4 commands I used on x86_64 Linux to build and run ArmVirtPkg:

$ OvmfPkg/build.sh -a AARCH64

$ OvmfPkg/build.sh -a AARCH64 qemu -m 1024 -cpu cortex-a57 -M virt -net none

$ OvmfPkg/build.sh -a ARM

$ OvmfPkg/build.sh -a ARM qemu -m 1024 -cpu cortex-a15 -M virt -net none

I think the script might be usable on an ARM based build systems as
well, but it might require further tweaks. Ideally, if the build
system was AARCH64 based, then:

* OvmfPkg/build.sh: (with no params) would cause AARCH64 ArmVirtPkg to
  be built using a native compiler.

* OvmfPkg/build.sh -a ARM: would cause ARM ArmVirtPkg to be built
  using a cross compiler.

* OvmfPkg/build.sh -a X64: would cause X64 OVMF to be built using a
  cross compiler.

I did create a cover letter, but then I deleted it. I thought I was
making too much out of it...

Personally I appreciate a cover letter even if it consists only of:
- public repo / branch reference
- one sentence on the goal
- a CC list
- cumulative diffstat

It helps a lot with grouping emails too.

> From what I gather, you don't find this script useful,

That's correct. I prefer to use the "build" utility directly, and I set
it up in every situation where it is needed specifically for that
situation/environment. I have a number of scripts around "build".

Regarding testing / launching QEMU, for years I've considered the QEMU
command line a computer-only interface. I do 99% of my testing via
libvirt, and for the remaining 1%, I have humongous hand-written command
lines, stashed in a bunch of scripts. Whenever I have to change to that
directory on my laptop, I cringe.

It's possible that some "simple" command lines exist for QEMU, but for
me they've always turned out deceptive. They are simple to *start*, but
soon you find you have to add 7 more options, and now your command line
stretches multiple lines in your terminal and it's hard to navigate, so
you start writing a script in order to break each option to a separate
line with a backslash, but then some individual options are still too
long to fit into 80 characters, so you introduce shell variables for
abbreviations, etc etc etc grrrrr. :)

Libvirt puts all that to rest.

> and therefore I sometimes wonder if I'm the only one that uses it. :)

I can't tell, but even if you are, that should be no problem! It's just
that I might not have much time to review or discuss changes to it. I
really dislike this situation, but I'm at the point where I'm
practically *stealing* the time to discuss anything that's not directly
assigned to me. :(
