[PATCH v5 0/5] ARM: omap[34]: Thumb-2 compatibility fixes

by Dave Martin

This set of patches, along with some other patches under discussion on alkml, should enable omap3 and omap4 kernels to be built with CONFIG_THUMB2_KERNEL. This patch set builds on recent cleanup done by the omap maintainers. At least some of this code definitely works, most features have been tested successfully. Further testing, especially of Thumb-2 behaviour, is still welcome. Seems to work with CONFIG_SMP_ON_UP and CONFIG_THUMB2_KERNEL enabled on Beagle xM A2 and Panda A1. Thanks also to Santosh Shilimkar and Kevin Hilman for their help with testing. v3: * make SMC instruction syntax more consistent * remove do_wfi() in favour of the generic wfi() macro v4: * revert to the OMAP-specific do_wfi() implementation, pending discussion of how generic macros can/should be provided v5: * use ARM for low-level code in mach-omap2/*34xx.S, for correct interoperation with non-Thumb-capable firmware. I've stripped the Acked/Tested-bys from the major patches to mach-omap2/*34xx.S, since the reversion to ARM constitutes a significant change -- I would be grateful if people could re- test / re-review if they have the chance. For best future compatibility, I've left the changes which avoid architecturally deprecated features. Details below. Cheers, Dave The patches can be found, along with a buildable working tree, in the following repo: git://git.linaro.org/people/dmart/linux-2.6-arm.git * arm/omap-thumb2: has the patches proposed here * arm/omap-thumb2+merged: additionally has some patches cherry- picked from other trees which are needed in order for the patches on arm/omap-thumb2 to work usefully. * dirty/arm/omap-thumb2+merged: buildable test tree, which adds 2 local patches to work around a toolchain bug. A working kernel config for this tree is here: http://people.linaro.org/~dmart/arm_omap-thumb2+v2_config : CONFIG_SMP_ON_UP=y CONFIG_THUMB2_KERNEL=y CONFIG_SERIAL_OMAP=y (to avoid garbage on xM; for Panda use console=ttyS2) (The config is derived from the linaro omap config and so turns on loads of modules -- don't feel you have to build them all...) Cherry-picked patches originated from Russell's devel tree and Tony Lindgren's omap-testing tree: http://ftp.arm.linux.org.uk/pub/linux/arm/kernel/git-cur/linux-2.6-arm.git devel git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git omap-testing This series also depends on one un-merged patch to generic-ise the wfi() macro: git://git.linaro.org/people/dmart/linux-2.6-arm.git arm/wfi-macro Dave Martin (5): ARM: omap4: Provide do_wfi() for Thumb-2 ARM: omap4: Convert END() to ENDPROC() for correct linkage with CONFIG_THUMB2_KERNEL ARM: omap3: Remove hand-encoded SMC instructions ARM: omap3: Thumb-2 compatibility for sram34xx.S ARM: omap3: Thumb-2 compatibility for sleep34xx.S arch/arm/mach-omap2/include/mach/omap4-common.h | 4 ++ arch/arm/mach-omap2/omap-headsmp.S | 2 +- arch/arm/mach-omap2/omap44xx-smc.S | 8 ++-- arch/arm/mach-omap2/sleep34xx.S | 62 ++++++++++++++++++---- arch/arm/mach-omap2/sram34xx.S | 36 ++++++++++--- 5 files changed, 87 insertions(+), 25 deletions(-)

This sounds like a lot of upfront work indeed, to make KMS more generic, though I think a number of driver would benefit from it eventually. It could be something for the Linaro graphics working group to look at in the following 11.11 release, depending on how many other people are interested in getting there. Arnd

Nice tool: chdist

by Michael Hope

Hi everyone. Loic pointed me at 'chdist', a nice tool that makes working with different releases much easier. You can use it to poke into and download packages from different releases without setting up a chroot for each one. I use from my Maverick host to grab the source packages from Natty when trying to track down a bug. For example, I'm looking into adding cortex-strings into the Natty libc6. Tell chdist about Natty by running: chdist create natty Update the list of packages using: chdist apt-get natty update Check which version is currently uploaded: chdist apt-cache natty show libc6 Grab the source: chdist apt-get natty source libc6 The distributions and configuration files end up under ~/.chdist such as ~/.chdist/natty/etc/apt/. -- Michael

cross-compile issue for overo

I just hit an issue cross-compiling the linux-linaro-2.6.37.git source. I'm seeing errors for arch/arm/mach-omap2/sleep34xx.S like: Error: selected processor does not support ARM mode `smc #1' It appears to be related to commit: 98be69a ARM: omap3: Remove hand-encoded SMC instructions After doing a little searching, I stumbled across something similar from John Rigby: http://marc.info/?l=linux-omap&m=129118316614865&w=2 I "fixed" the problem on my system with this patch: diff --git a/arch/arm/mach-omap2/Makefile b/arch/arm/mach-omap2/Makefile index f6614a6..985bc89 100644 --- a/arch/arm/mach-omap2/Makefile +++ b/arch/arm/mach-omap2/Makefile @@ -68,7 +68,7 @@ obj-$(CONFIG_OMAP_SMARTREFLEX) += sr_device.o smartre obj-$(CONFIG_OMAP_SMARTREFLEX_CLASS3) += smartreflex-class3.o AFLAGS_sleep24xx.o :=-Wa,-march=armv6 -AFLAGS_sleep34xx.o :=-Wa,-march=armv7-a +AFLAGS_sleep34xx.o :=-Wa,-march=armv7-a$(plus_sec) ifeq ($(CONFIG_PM_VERBOSE),y) CFLAGS_pm_bus.o += -DDEBUG My question: Is this patch actually needed for cross-compiling our kernel, or is there some additional argument I need to pass to Make when building my kernel?
