arch: microblaze: Remove CONFIG_OPROFILE support

2021-01-22T06:42:23+00:00

The "oprofile" user-space tools don't use the kernel OPROFILE support any more, and haven't in a long time. User-space has been converted to the perf interfaces. Remove the old oprofile's architecture specific support.

microblaze: Remove noMMU code

2020-11-26T15:39:35+00:00

This configuration is obsolete and likely none is really using it. That's why remove it to simplify code. Note about CONFIG_MMU in hw_exception_handler.S is left intentionally for better comment understanding.

microblaze: fix race condition in building boot images

2018-12-14T07:09:21+00:00

I fixed a race condition in the parallel building of ARM in commit 3939f3345050 ("ARM: 8418/1: add boot image dependencies to not generate invalid images"). I see the same problem for MicroBlaze too. "make -j ARCH=microblaze all linux.bin.ub" results in a broken build because two threads descend into arch/microblaze/boot simultaneously. Add proper dependencies to avoid it.

microblaze: add linux.bin* and simpleImage.* to PHONY

2018-12-14T07:09:20+00:00

linux.bin, linux.bin.gz, and linux.bin.ub are phony targets to generate a corresponding image under arch/microblaze/boot/. simpleImage.% also works like a phony target, but a pattern that contains '%' cannot be a phony target. I replaced it with equivalent simpleImage.$(DTB). Signed-off-by: Masahiro Yamada Signed-off-by: Michal Simek

microblaze: fix multiple bugs in arch/microblaze/boot/Makefile

2018-12-14T07:09:20+00:00

This commit fixes some build issues. The first issue is the breakage of linux.bin.ub target since commit ece97f3a5fb5 ("microblaze: Fix simpleImage format generation") because the addition of UIMAGE_{IN,OUT} affected it. make ARCH=microblaze CROSS_COMPILE=microblaze-linux- linux.bin.ub [ snip ] OBJCOPY arch/microblaze/boot/linux.bin UIMAGE arch/microblaze/boot/linux.bin.ub.ub /usr/bin/mkimage: Can't open arch/microblaze/boot/linux.bin.ub: No such file or directory make[1]: *** [arch/microblaze/boot/Makefile;14: arch/microblaze/boot/linux.bin.ub] Error 1 make: *** [arch/microblaze/Makefile;83: linux.bin.ub] Error 2 The second issue is the use of the "if_changed" multiple times for the same target. As commit 92a4728608a8 ("x86/boot: Fix if_changed build flip/flop bug") pointed out, this never works properly. Moreover, generating multiple images as a side-effect is confusing. Let's split the build recipe for each image. simpleImage.

*.unstrip is just a copy of vmlinux. simpleImage.

and simpleImage.

.ub are created in the same way as linux.bin and linux.bin.ub, respectively. I kept simpleImage.* recipes independent of linux.bin.* ones to not change the behavior. Lastly, this commit fixes "make ARCH=microblaze clean". Previously, it only cleaned up the unstrip image. Now, all the simpleImage files are cleaned.

microblaze: move "... is ready" messages to arch/microblaze/Makefile

2018-12-14T07:09:19+00:00

To prepare for more fixes, move this to arch/microblaze/Makefile. Otherwise, the same "... is ready" would be printed multiple times. Signed-off-by: Masahiro Yamada Signed-off-by: Michal Simek

microblaze: adjust the help to the real behavior

2018-12-14T07:09:19+00:00

"make ARCH=microblaze help" mentions simpleImage.

.unstrip, but it is not a real Make target. It does not work because Makefile assumes "system.unstrip" is the name of DT. $ make ARCH=microblaze CROSS_COMPILE=microblaze-linux- simpleImage.system.unstrip [ snip ] make[1]: *** No rule to make target 'arch/microblaze/boot/dts/system.unstrip.dtb', needed by 'arch/microblaze/boot/dts/system.dtb'. Stop. make: *** [Makefile;1060: arch/microblaze/boot/dts] Error 2 make: *** Waiting for unfinished jobs.... simpleImage.

works like a phony target that generates multiple images. Reflect the real behavior. I removed the DT directory path information because it is already explained a few lines below. While I am here, I deleted the redundant *_defconfig explanation. The top-level Makefile caters to list available defconfig files: mmu_defconfig - Build for mmu nommu_defconfig - Build for nommu Signed-off-by: Masahiro Yamada Signed-off-by: Michal Simek

microblaze: generate uapi header and system call table files

2018-11-16T07:24:34+00:00

System call table generation script must be run to gener- ate unistd_32.h and syscall_table.h files. This patch will have changes which will invokes the script. This patch will generate unistd_32.h and syscall_table.h files by the syscall table generation script invoked by microblaze/Makefile and the generated files against the removed files must be identical. The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/syscall_table.S file.
