[PATCH 0/9] V2: Add machine qemuaarch64

[Kai Kang]

V2:
* fix kernel linux-yocto build faiure
* redefine position of dynamic linker from /lib to /lib64
* other fixes of userspace packages

Test with Joe Slater's patches:
* siteinfo: account for 32 and 64 bit arm
* sysprof: add aarch64 support

The following changes since commit fceef0cace6670a8c5f15cd2f31a191176732730:

  bitbake: data_smart: Fix remove operator and its interaction with data expansion (2014-09-13 08:52:49 +0100)

[PATCH 1/9] linux-yocto: depend on libgcc for aarch64

[Kai Kang]

Make aarch aarch64 kernel depend on libgcc. In arch/arm64/Makefile, it
adds LIBGCC to libs-y:

LIBGCC          := $(shell $(CC) $(KBUILD_CFLAGS) -print-libgcc-file-name)
libs-y          += $(LIBGCC)

If build without libgcc, the value of LIBGCC is just libgcc.a without
parent directory. linux-yocto fails to build:

|   LD      vmlinux.o
| aarch64-poky-linux-ld.bfd: cannot find libgcc.a: No such file or directory

Add libgcc to aarch64 kernel dependency.

[PATCH 2/9] Add machine qemuarm64

[Kai Kang]

Add machine qemuarm64. The configure files are derived from linaro.

Update:
* rename genericarmv8 to qemuarm64 for coordination in oe-core
* include qemu.inc then remove common part of config
* disable using autoserial
* move arch-armv8.inc from machine/include/arm64 to machine/include/arm

And set BASELIB to lib64 in bitbake.conf. libgcc uses
'aarch64-poky-linux-gcc -print-multi-os-directory' to get install
directory that the value is 'lib64' then cause [installed-vs-shipped]
error. The value is set in gcc source file gcc/config/aarch64/t-aarch64-linux.

[PATCH 3/9] gcc-4.9: redefine dynamic linker for aarch64

[Kai Kang]

Redefine dynamic linker for aarch64 from /lib to /lib64.

BASELIB of aarch64 has to be defined with 'lib64', then linker file
ld-linux-aarch64.so.1 is installed into /lib64 rather than /lib. So
update it here too.

+Subject: [PATCH] Fix AArch64/arm64 detection.
+
+The detection needs to go before arm, else the system will detect AArch64/arm64
+as arm.
+
+This patch comes from Wookey, he has agreed to put it under BSD or Expat
+to allow it's inclusion in here:

+Subject: [PATCH] Add qatomic support for AArch64 (aka arm64).
+
+Patch by Mark Salter <msalter@redhat.com>
+licensed under BSD:
+
+<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=735488#195>
+
+This patch is known to not be the most correct way
+to implement them, as it seems to be possible to do it in a faster way,
+but should work non the less until we can provide something better.

[PATCH 6/9] qt4: add aarch64 support

[Kai Kang]

Add qt4 aarch64 support. Use same patches with qt-native. Add arch check
to set right QT_ARCH.

Disable webkit temporarily that it fails to build:

| runtime/JSValueInlineMethods.h: In constructor
'JSC::JSValue::JSValue(const JSC::JSCell*)':
| runtime/JSValueInlineMethods.h:242:78: error: cast from 'JSC::JSCell*'
to 'int32_t {aka int}' loses precision [-fpermissive]

It has been fix by Qt5, but didn't backport to Qt4. There is an still open
defect for it:
https://bugreports.qt-project.org/browse/QTBUG-35442

Add there are 2 known failures of build world:
1 meta/recipes-kernel/cryptodev/cryptodev-module_1.6.bb: it needs a 
valid kernel config. CONFIG_MODULES is not set for now.
2 meta/recipes-support/libunwind/libunwind_1.1.bb: it was added recently 
and seems not support aarch64. Maybe we should exclude it from world for 
aarch64.

Kai

So aarch64 support really needs qemuarm64 in oe-core to be tested, and
qemuarm64 is a new feature, and we froze for new features two weeks
ago.  Blindly merging aarch64 patches that we can't currently test
doesn't seem sensible.

Could someone who is actually testing and working on the aarch64
support (you?) manage a single branch that tracks master, so when 1.7
branches off we can do a merge straight away.

really ? usually kernel has its own routines to substitute libgcc needs.
why is it different here.

hmmm since the ldso name is different it can still live in /lib
and there will be ilp32 version ldso multilib as well later. can we keep
ldso in /lib ?

It calls script link-vmlinux.sh to link vmlinux.o. It runs function 
vmlinux_link() in the script:

if [ "${SRCARCH}" != "um" ]; then
${LD} ${LDFLAGS} ${LDFLAGS_vmlinux} -o ${2} \
-T ${lds} ${KBUILD_VMLINUX_INIT} \
--start-group ${KBUILD_VMLINUX_MAIN} --end-group ${1}

var KBUILD_VMLINUX_MAIN is defined in top Makefile:

export KBUILD_VMLINUX_MAIN := $(core-y) $(libs-y) $(drivers-y) $(net-y)


And arch aarch64 adds LIBGCC to var libs-y:

LIBGCC          := $(shell $(CC) $(KBUILD_CFLAGS) -print-libgcc-file-name)
libs-y          += $(LIBGCC)


If doesn't do libgcc:popualte_sysroot, LIBGCC just get value 'libgcc.a' 
rather than 'absolute path' to libgcc.a.

In script link-vmlinux.sh, it expands to:

+ modpost_link vmlinux.o
+ aarch64-poky-linux-ld.bfd -r -o vmlinux.o arch/arm64/kernel/head.o 
init/built-in.o --start-group usr/built-in.o 
arch/arm64/kernel/built-in.o arch/arm64/mm/built-in.o kernel/built-in.o 
mm/built-in.o fs/built-in.o ipc/built-in.o security/built-in.o 
crypto/built-in.o block/built-in.o arch/arm64/lib/lib.a lib/lib.a 
*libgcc.a* arch/arm64/lib/built-in.o lib/built-in.o *libgcc.a* 
drivers/built-in.o sound/built-in.o firmware/built-in.o net/built-in.o 
--end-group

Because no libgcc.a in current directory, error shows twice:

aarch64-poky-linux-ld.bfd: cannot find libgcc.a: No such file or directory
aarch64-poky-linux-ld.bfd: cannot find libgcc.a: No such file or directory

So I add libgcc as dependency of aarch64 kernel.


And one thing more, in kernel source directory arch, only few arches 
depends on LIBGCC:

$ grep -rw LIBGCC arch/
./openrisc/Makefile:LIBGCC := $(shell $(CC) $(KBUILD_CFLAGS) 
-print-libgcc-file-name)
./openrisc/Makefile:libs-y += $(LIBGCC)
./parisc/Makefile:LIBGCC = $(shell $(CC) $(KBUILD_CFLAGS) 
-print-libgcc-file-name)
./parisc/Makefile:libs-y += arch/parisc/lib/ $(LIBGCC)
./hexagon/Makefile:LIBGCC := $(shell $(CC) $(KBUILD_CFLAGS) 
-print-libgcc-file-name)
./hexagon/Makefile:libs-y += $(LIBGCC)
./arc/Makefile:LIBGCC := $(shell $(CC) $(ARC_LIBGCC) $(cflags-y) 
--print-libgcc-file-name)
./arc/Makefile:libs-y += arch/arc/lib/ $(LIBGCC)
./m32r/Makefile:LIBGCC := $(shell $(CC) $(KBUILD_CFLAGS) 
-print-libgcc-file-name)
./m32r/Makefile:libs-y += arch/m32r/lib/ $(LIBGCC)
./xtensa/Makefile:LIBGCC := $(shell $(CC) $(KBUILD_CFLAGS) 
-print-libgcc-file-name)
./xtensa/Makefile:libs-y += arch/xtensa/lib/ $(LIBGCC)
./xtensa/boot/boot-redboot/Makefile:LIBGCC := $(shell $(CC) 
$(KBUILD_CFLAGS) -print-libgcc-file-name)
./xtensa/boot/boot-redboot/Makefile: $(Q)$(LD) $(LD_ARGS) -o $@ $^ 
-L/xtensa-elf/lib $(LIBGCC)
./cris/Makefile:LIBGCC = $(shell $(CC) $(KBUILD_CFLAGS) 
-print-file-name=libgcc.a)
./cris/Makefile:libs-y += arch/cris/$(SARCH)/lib/ $(LIBGCC)
./arm64/Makefile:LIBGCC := $(shell $(CC) $(KBUILD_CFLAGS) 
-print-libgcc-file-name)
./arm64/Makefile:libs-y += $(LIBGCC)


By coincidence, there is no arch Yocto support before.

Should not we use '/lib64' and '/lib' for mutlilib? I remember 
intel-x86-64 uses that way rather than '/lib' and '/lib32'.

I thought the upstream definition (managed by ARM Ltd, and Linaro) for the ld.so 
had changed a few months back so that /lib64 was the 'standard' location for the 
ldso.  Perhaps I'm mistaken?

I did some research and I'm confused.. aarch64 is screwed up by consensus 
apparently..

Dynamic libraries live in /lib64, and the dynamic linker in /lib.. Whee!

So ya, this patch isn't correct.. the dynamic linker needs to stay in /lib. 
(Nothing says you can't sym/hardlink to lib64.. but it has to refer to in in 
/lib for the ABI conformance.)

OK. Keep dynamic linker in /lib and change libraries directory from 
/lib64 to /lib.

The dynamic linker (ldso) goes into '/lib'.  The library directory is /lib or 
/lib64.  (/lib64 when multilib arm is enabled.)  It's a bit odd, but it means 
that the link inside of gcc must be hard coded to the default /lib/... path.

The shared libraries would be referenced in the same way they are in the other 
distributions where either lib, lib64 (or any alternative can be set in the OE 
code.)
