[Buildroot] [PATCH V2 1/9] arch/csky: Add VDSP and FLOAT_ABI compiler options.

[Buildroot] [PATCH V2 1/9] arch/csky: Add VDSP and FLOAT_ABI compiler options.

[guoren at kernel.org]

From: Guo Ren <ren_guo@c-sky.com>

We never use BR2_CSKY_DSP in buildroot and we use VDSP instead. For
float compiling, we need -mfloat-abi=xxx.

[Buildroot] [PATCH V2 1/9] arch/csky: Add VDSP and FLOAT_ABI compiler options.

[Thomas Petazzoni]

Hello,

This is not true, BR2_CSKY_DSP is used:

arch/Config.in.csky:    default "ck610"         if (BR2_ck610 && !BR2_CSKY_FPU && !BR2_CSKY_DSP)
arch/Config.in.csky:    default "ck807"         if (BR2_ck807 && !BR2_CSKY_FPU && !BR2_CSKY_DSP)
arch/Config.in.csky:    default "ck807e"        if (BR2_ck807 && !BR2_CSKY_FPU &&  BR2_CSKY_DSP)
arch/Config.in.csky:    default "ck807f"        if (BR2_ck807 &&  BR2_CSKY_FPU && !BR2_CSKY_DSP)
arch/Config.in.csky:    default "ck807ef"       if (BR2_ck807 &&  BR2_CSKY_FPU &&  BR2_CSKY_DSP)
arch/Config.in.csky:    default "ck810"         if (BR2_ck810 && !BR2_CSKY_FPU && !BR2_CSKY_DSP)
arch/Config.in.csky:    default "ck810e"        if (BR2_ck810 && !BR2_CSKY_FPU &&  BR2_CSKY_DSP)
arch/Config.in.csky:    default "ck810f"        if (BR2_ck810 &&  BR2_CSKY_FPU && !BR2_CSKY_DSP)
arch/Config.in.csky:    default "ck810ef"       if (BR2_ck810 &&  BR2_CSKY_FPU &&  BR2_CSKY_DSP)

so as such, your patch is incorrect: you remove an option, but the
option is still being used.

If this option is not needed because in fact the DSP enhanced
instructions have never been used, then please have a patch that *ONLY*
removes the BR2_CSKY_DSP option (both its definition and where it is
used).

Then another patch that adds the BR2_CSKY_VDSP option.

And finally another that sets the BR2_GCC_TARGET_FLOAT_ABI value.

All of these topics are independent from each other, they should be in
separate patches.

Thanks,

Thomas

Another comment: you add an option that depends on BR2_ck860 in this
PATCH 1, but BR2_ck860 is only added in PATCH 2. This is not correct.

[Buildroot] [PATCH V2 2/9] arch/csky: Add ck860 and -mcpu compiler options

Adding ck860 support and moving -mcpu handling in arch.mk.csky are two
independent things. Please make the move to arch.mk.csky first without
ck860, as a cleanup, in a first patch, and then another patch does the
addition of ck860 support.

So in PATCH 1, VDSP is only for CK860, but now it's for all cores that
have a FPU, which includes CK810 and CK807. It should be consistent
from the start, i.e from the point where VDSP is introduced.

This should go to the patch cleaning up the logic to use arch.mk.csky.

Same.

This should go to the patch adding the BR2_CSKY_VDSP option.

The ordering is not good: you can't remove this "select" until all the
toolchain components have C-SKY support added. So this patch should
come later in the series, it should actually be one of the last patch,
and should be: "arch/csky: enable internal toolchain backend" or
something like that.

This should be a separate patch.

Let's do it like we do for the ARC architecture: add an option, and the
proper depends on. I.e:

choice
        prompt "Binutils Version"
        default BR2_BINUTILS_VERSION_ARC if BR2_arc
	default BR2_BINUTILS_VERSION_CSKY if BR2_csky
        default BR2_BINUTILS_VERSION_2_31_X
        help
          Select the version of binutils you wish to use.

config BR2_BINUTILS_VERSION_2_30_X
        bool "binutils 2.30"
	depends on !BR2_csky

config BR2_BINUTILS_VERSION_2_31_X
        bool "binutils 2.31.1"
	depends on !BR2_csky

config BR2_BINUTILS_VERSION_2_32_X
        bool "binutils 2.32"
	depends on !BR2_csky

config BR2_BINUTILS_VERSION_ARC
        bool "binutils arc (2.31)"
        depends on BR2_arc

config BR2_BINUTILS_VERSION_CSKY
        bool "binutils csky (2.32)"
        depends on BR2_csky

endchoice

config BR2_BINUTILS_VERSION
        string
	default "c66d8bbcebfddf713b2b436e1b135e6b125a55a5" if BR2_BINUTILS_VERSION_CSKY
        default "arc-2019.03-rc1"       if BR2_BINUTILS_VERSION_ARC
        default "2.30"          if BR2_BINUTILS_VERSION_2_30_X
        default "2.31.1"        if BR2_BINUTILS_VERSION_2_31_X
        default "2.32"          if BR2_BINUTILS_VERSION_2_32_X

Same here, please follow the same logic as the one used for ARC, for
consistency, i.e:

# Version is set when using buildroot toolchain.
# If not, we do like other packages
BINUTILS_VERSION = $(call qstrip,$(BR2_BINUTILS_VERSION))
ifeq ($(BINUTILS_VERSION),)
ifeq ($(BR2_arc),y)
BINUTILS_VERSION = arc-2019.03-rc1
else ifeq ($(BR2_csky),y)
BINUTILS_VERSION = c66d8bbcebfddf713b2b436e1b135e6b125a55a5
else
BINUTILS_VERSION = 2.31.1
endif
endif # BINUTILS_VERSION

ifeq ($(BINUTILS_VERSION),arc-2019.03-rc1)
BINUTILS_SITE = $(call github,foss-for-synopsys-dwc-arc-processors,binutils-gdb,$(BINUTILS_VERSION))
BINUTILS_SOURCE = binutils-gdb-$(BINUTILS_VERSION).tar.gz
BINUTILS_FROM_GIT = y
else ifeq ($(BINUTILS_VERSION),c66d8bbcebfddf713b2b436e1b135e6b125a55a5)
BINUTILS_SITE = $(call github,c-sky,binutils-gdb,$(BINUTILS_VERSION))
BINUTILS_SOURCE = binutils-$(BINUTILS_VERSION).tar.gz
BINUTILS_FROM_GIT = y
endif

What we're doing for ARC is made not the best, but being consistent in
how different architectures do it is much more important.

Thanks,

I don't see what will prevent me from selecting an upstream gcc 6.x or
7.x for C-SKY here. Are you sure you should not add a bunch of "depends
on !BR2_csky" to the other gcc version options ?

Thanks!

I think this should explain what is supported and not supported:

 - Building host-gdb ?

 - Building gdbserver for the target ?

 - Building full gdb for the target ?

So building host-gdb is not possible ? Which means remote debugging is
not possible ?

This seems a bit odd because board/csky/readme.txt precisely suggests
to use host-gdb:

../host/bin/csky-linux-gdb -x ../../board/csky/gx6605s/gdbinit vmlinux

And you confirm you support both gdbserver and full gdb on the target ?

No, we could build out host-gdb for remote debugging. Becasue the
!BR2_csky just make no BR2_GDB_VERSION_XXX and disable
BR2_PACKAGE_GDB_NEEDS_CXX11, BR2_GDB_VERSION.

In gdb.mk we overwrite the GDB_VERSION with a commit version. I'll
move the version define in Config.in.host.

Package/gdb could build out csky-linux-gdb for remote debug.

I've slightly improved the commit message, and applied to master. I've
applied to master and not to next, because this commit is really
important: without it, none of the autotools based packages can build
on C-SKY (which is not yet tested in the autobuilders).

Best regards,

I agree that this minimal change is probably the most sensible thing to
do for master, but for next it IMHO makes more sense to update our
config.sub / config.guess copies, as upstream has gained csky support
since:

commit 63b4ce2e8c28aee6a32133e400436e4ca885215a
Author: Mao Han <han_mao@c-sky.com>
Date:   Mon Apr 16 14:46:36 2018 +1000

           * config.sub (csky, csky-*): Recognise.
           * testsuite/config-sub.data: Add a test case.

Agreed. I hadn't checked upstream gnuconfig, but it indeed makes a lot
of sense to update our gnuconfig copy using the latest upstream version.
