PATCH v3 1/1 package/iqvlinux: new package

The PCI support needs to be checked since this driver is based on it. Otherwise the build fail with:
#error "This driver requires PCI support to be available"

But this message is concealed by several occurrence of this
one:
error: implicit declaration of function 'pci_find_bus' [-Werror=implicit-function-declaration]

Cc Arnout Vandecappelle <[email protected]>

---
v3: changes suggested by Arnout
- remove the patch and use CC=$(TARGET_CC) instead.
- Add a 'or' between GPLv2 and BSD-3c for license information
- Add some more license files (files.txt)
- Fixes typos and indentation.
- move the check for PCI option to LINUX_POST_CONFIGURE_HOOKS
- redirect echo to stderr.
v2: - rename the package simply to iqvlinux (ThomasP)
- move it to "Hardware Handling" menu (ThomasP)
- Cc Yann for the kernel-module infra
- Add a check for CONFIG_PCI even if it's redundant with the message from the Makefile.
(Do we really need this check ?)

I think we don't really care. There are lots of other kernel modules or Linux kernel extensions (Xenomai, RTAI) for which we don't do such version checks.

I agree on the principle, but I think we should rather handle that like we do for other options: enable automatically the needed option.

Remember how someone proposed to check for CONFIG_MODULES=y and error out if not available? Instead, you implemented b7c32c98bc810b88e0391117f225658f82b44995.

So a little bit in the direction of what you proposed, what about refactoring the LINUX_NEEDS_MODULES mechanism into a more generic mechanism that allows package to express which kernel option(s) they need, and automatically enable such options in linux/linux.mk when configuring the kernel.

Best regards,

Thomas

I'm not totally oposed to this idea.

Unless we don't care about runtime consistency, and just care about the buildability of the configuration...

However, I like doing such little tiny bit of infra, so I can append that to my todo-list. What do you prefer: setting the option (like for modules), or checking the option?

Except that I disagree with Arnout :)

Arnout is not making the difference between being able to *build* and being able to *run*.

CONFIG_PCI is needed for the build to proceed, so it is normal that we enable it automatically. The PCI root complex drivers are only needed for the PCI support to actually work on the target, not for iqvlinux to build.

And the story is the same for xtable-addons: the additions in linux.mk were made because those kernel options were needed for xtable-addons to simply *build*.

I think we should follow the principle of least surprise. We should avoid
situations where a package builds and we know for sure it will not work at runtime. In many cases, this cannot be avoided, but if we can avoid it, we should.

With xtables it's slightly different since if we enable those kernel config
options, it will actually work at runtime (at least as far as we can tell). Similar for the systemd options - which BTW are really runtime-only, systemd doesn't check for them at all at build time.

Fortunately, what you've committed amounts to a build-time check: the iqvlinux
build will error out if CONFIG_PCI isn't enabled. The error message will be cryptic and will not tell the user how to fix it, but at least it is less cryptic than when the user enables the package and it simply doesn't do anything without any error message at all.

So basically, the check added by Romain is just making the build error message
less cryptic, so it is really optional.

Regards,
Arnout

It's not really that we *KNOW* that it won't build, it is more that we cannot *GUARANTEE* that it will.

For this specific case, I think the issue is moot as people using this package are most likely on x86 (where having a kernel config without PCI is very unlikely), or atleast on a platform with PCI support enabled (otherwise they cannot use the Intel MAC).

But yeah, I agree that we should try to make things work out of the box (both build and runtime) where possible.

Yes, it is really needed. The kernel buildsystem indeed defines CC, but it gets re-defined by the iqvlinux Makefile, which gets included by the kernel buildsystem since we do M=/path/to/iqvlinux to build the iqvlinux module.

 create mode 100644 package/iqvlinux/Config.in
 create mode 100644 package/iqvlinux/iqvlinux.hash
 create mode 100644 package/iqvlinux/iqvlinux.mk

Applied after doing the following changes:

[Thomas:
- fix minor typo in Config.in: s/Enthernet/Ethernet/
- license is "GPLv2, BSD-3c", not "GPLv2 or BSD-3c"
- remove IQVLINUX_PCI_CHECK, until a proper generic solution is implemented.]

As you can see, I've removed the IQVLINUX_PCI_CHECK so that a nicer solution can be discussed/implemented with Yann. However, since this check was not really mandatory, I decided to add the package nonetheless (albeit without the check).

Thanks!

Dear Romain Naour,

Quoted 25 lines · Romain Naour

The PCI support needs to be checked since this driver is based on it. Otherwise the build fail with:
#error "This driver requires PCI support to be available"

But this message is concealed by several occurrence of this
one:
error: implicit declaration of function 'pci_find_bus' [-Werror=implicit-function-declaration]

Cc Arnout Vandecappelle <[email protected]>

v3: changes suggested by Arnout
- remove the patch and use CC=$(TARGET_CC) instead.
- Add a 'or' between GPLv2 and BSD-3c for license information
- Add some more license files (files.txt)
- Fixes typos and indentation.
- move the check for PCI option to LINUX_POST_CONFIGURE_HOOKS
- redirect echo to stderr.
v2: - rename the package simply to iqvlinux (ThomasP)
- move it to "Hardware Handling" menu (ThomasP)
- Cc Yann for the kernel-module infra
- Add a check for CONFIG_PCI even if it's redundant with the message from the Makefile.
(Do we really need this check ?)

Ok, it's not a problem for me. The kernel I use already have CONFIG_PCI enabled. I'll follow the discussion about the kernel option check.

Best regards,
Romain
