* [PATCH 1/1] EmbeddedPkg/TimeBaseLib: Add macros to get build year/month/day @ 2020-07-24 16:37 Pete Batard 2020-08-03 12:09 ` Leif Lindholm 0 siblings, 1 reply; 4+ messages in thread From: Pete Batard @ 2020-07-24 16:37 UTC (permalink / raw) To: devel; +Cc: ard.biesheuvel, leif These can be used, for instance, to automate the population of an SMBIOS Type 0 BIOS Release Date when building a UEFI firmware (which is how we plan to use these macros for the Raspberry Pi platform). These macros should work for any compiler that follows ISO/IEC 9899, but we add a check for the compiler we have tested to be on the safe side. Note that we decided against adding a #error or #warn for compilers that haven't been validated, as we don't want to introduce breakage for people who may already be using the header with something else than gcc, MSVC or Clang. Instead, we expect those to send a patch that adds their compiler to the list, once they have tested the macros there.

I tend to find it inconvenient to reference to work that has not yet been integrated, as I'm not sure how you're suppose to reference it. Should you point to an edk2-devel post in the commit message? In the cover letter? Something else? As a result, provided the dependency should be simple enough to review independently, I prefer to alleviate that issue by just waiting for it to be integrated. But if that's a problem, I can certainly ensure that future co-dependent patches are submitted together. > Anyway: > Reviewed-by: Leif Lindholm <leif@nuviainc.com> > Pushed as bbb8a8185838.

Should > you point to an edk2-devel post in the commit message? In the cover letter? > Something else? The cover letter is a good place to describe such dependencies. We always merge edk2 portions before edk2-platforms, so once it's merged the only ordering requirement is that your edk2 isn't older than your edk2-platforms. Hence, we don't really need it in commit messages. > As a result, provided the dependency should be simple enough to review > independently, I prefer to alleviate that issue by just waiting for it to be > integrated.

In this particular case, it wasn't actually important, we just ended up with mismatched expectations. Since it was fairly isolated code that I had already been able to test build in my environments when it formed part of the original driver.
