linux recipe PV requirements

linux recipe PV requirements

[Darren Hart]

Are there restrictions on what the PV variable is set to?

I'd like to name the recipe I'm working on linux-linaro-2.6.35 and use 
PR and the git AUTOREV to define the PV value. However, when I make the 
following change in linux-linaro-2.6.35_git.bb:

- PV = "2.6.35"
+ PV = "${PR}+git${SRCREV}"


I get the following failure:

$ bitbake linux-linaro-2.6.35

You need a kernel version in there, kernel.bbclass adds a depends to the
kernel of:

virtual/${TARGET_PREFIX}depmod-${@get_kernelmajorversion('${PV}')}

The get_kernelmajorversion() function in linux-kernel-base.bbclass is
failing to determine the kernel version and returning None which results
in the unbuildable dependency error you are seeing.

For further reference I'd point you at the PV's set by other git kernel
recipes:

joshual@scimitar:~/Projects/Yocto/poky/meta/recipes-kernel/linux
$ git grep PV\ =
linux-omap-zoomsync_2.6.32.bb:PV = "2.6.32.7-${OEV}"
linux-omap2_git.bb:PV = "2.6.26"
linux-omap2_git.bb:#PV = "2.6.26+2.6.27-rc1+${PR}+git${SRCREV}"
linux-omap3-pm_git.bb:PV = "2.6.31-rc7+pm+${PR}+git${SRCREV}"
linux-omap3_git.bb:PV = "2.6.27-rc6+${PR}+git${SRCREV}"
linux-yocto_git.bb:PV = "2.6.34+git${SRCPV}"

Cheers,
Joshua

Thanks Josh,

This is the sort of dependency I was looking for. Knowing this, I 
suppose the best thing to do is rename linux-linaro-2.6.35_git to 
linux-linaro-stable_git. I don't particularly care for this approach as 
"stable" is sure to change to a different version in the future - but 
then again, perhaps this is inline with Poky's goals of having a single 
known-good version of a package.

I'll work on updating this upon my return.

Thanks again for the info! While I can find things like the above, I'm 
not yet confident enough to affirmatively attribute them to the failures 
I was seeing.
