From: ayaka <ayaka@soulik.info>

There are some addtional instructions apart from bare armv8,
also there is armv8.1, armv8.2.

Most the processor would support crc, except X-gene 1.

Renaming the file when other things use it causes failures:

my bad. I have been testing this with rpi3_64 and missed the qemuarm64
part, I sent a patch to use armv8a instead for qemuarm64, since thats
more used configuration when it comes to armv8

We have had these tune files sent by other folks in the past. Does this
settle all the questions from back then ?

It was sent couple months ago, you can find the discussion in various
threads, e.g.:
http://lists.openembedded.org/pipermail/openembedded-core/2015-October/111318.html
http://lists.openembedded.org/pipermail/openembedded-core/2015-November/112907.html

http://lists.openembedded.org/pipermail/openembedded-core/2016-March/118579.html

and more.

This I have looked at. Eventually, I plan to add aarch32 bit tunes as well
for now, I just want to make aarch64 piece look good with option to
have aarch32 in mind, if there are specific questions I would be
interested to here

I believe that this change, along with
6719de403620dded075dc74f2976669d95bffd7a, may have broken multilib for
AArch64. :(

When I enable multilib in local.conf with:

 require conf/multilib.conf
 MULTILIBS = "multilib:lib32"
 DEFAULTTUNE_virtclass-multilib-lib32 = "armv7at-neon"

then both the primary target and lib32- packages end up installing stuff
into /usr/lib (and would presumably conflict, if I got as far as installing
them.)

If I revert 6719de403620dded075dc74f2976669d95bffd7a and
d1db78b0e284e1a1f370e71183ded0cbdc1475db then the primary target packages
end up installing stuff in /usr/lib64 as would be expected.

This appears to be because baselib = "lib" rather than "lib64". That in
turn may be because BASE_LIB_tune-armv8a-crc does not exist.

If I apply this patch:


then multilib behaves as it did before. Is this the correct fix?

Thanks.

Mike.

it is in right direction, while you are at it also add it for other armv8 tunes
