| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of remembering to specify DTB= on the make commandline, this commit allows the much friendlier make simpleImage.<dts> where <dts>.dts is expected to be found in arch/microblaze/boot/dts/ The resulting vmlinux, with the compiled DTS linked in, will be copied to boot/simpleImage.<dts> This mirrors the same functionality as on PowerPC, albeit achieving it in a slightly different way. + strip simpleImage file The size of output file is very similar to linux.bin. vmlinux - full elf without fdt blob simpleImage.<dtb name>.unstrip - full elf with fdt blob simpleImage.<dtb name> - stripped elf with fdt blob Add symlink to generic system.dts in platform folder Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

| | | | | | | | | | | | | | | | | | _start is setup to physical kernel start address. This caused that when you load vmlinux (with MMU kernel) via XMD program counter (pc) is setup correctly and then you can write con and start kernel. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * microblaze: Use LOAD_OFFSET macro to get correct LMA for all sectionsMichal Simek2009-09-221-15/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, vmlinux has LMA==VMA for all sections, which is wrong for MMU kernels. Previous patches in this series defined the LOAD_OFFSET constant, now we make use of it in our link script. Other minor changes in this patch: * brace/indenting cleanup of some sections * put __fdt_* symbols in their own section, and apply LOAD_OFFSET fixup Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

| | | | | | | | | | | | | | | | LOAD_OFFSET is the offset between the physical load address and the kernel's virtual address.

* | perf: Do the big rename: Performance Counters -> Performance EventsIngo Molnar2009-09-212-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bye-bye Performance Counters, welcome Performance Events! In the past few months the perfcounters subsystem has grown out its initial role of counting hardware events, and has become (and is becoming) a much broader generic event enumeration, reporting, logging, monitoring, analysis facility. Naming its core object 'perf_counter' and naming the subsystem 'perfcounters' has become more and more of a misnomer. With pending code like hw-breakpoints support the 'counter' name is less and less appropriate. All in one, we've decided to rename the subsystem to 'performance events' and to propagate this rename through all fields, variables and API names. (in an ABI compatible fashion) The word 'event' is also a bit shorter than 'counter' - which makes it slightly more convenient to write/handle as well. Thanks goes to Stephane Eranian who first observed this misnomer and suggested a rename. User-space tooling and ABI compatibility is not affected - this patch should be function-invariant. (Also, defconfigs were not touched to keep the size down.) This patch has been generated via the following script: FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/PERF_EVENT_/PERF_RECORD_/g' \ -e 's/PERF_COUNTER/PERF_EVENT/g' \ -e 's/perf_counter/perf_event/g' \ -e 's/nb_counters/nb_events/g' \ -e 's/swcounter/swevent/g' \ -e 's/tpcounter_event/tp_event/g' \ $FILES for N in $(find . -name perf_counter.[ch]); do M=$(echo $N | sed 's/perf_counter/perf_event/g') mv $N $M done FILES=$(find . -name perf_event.*) sed -i \ -e 's/COUNTER_MASK/REG_MASK/g' \ -e 's/COUNTER/EVENT/g' \ -e 's/\<event\>/event_id/g' \ -e 's/counter/event/g' \ -e 's/Counter/Event/g' \ $FILES ... to keep it as correct as possible. This script can also be used by anyone who has pending perfcounters patches - it converts a Linux kernel tree over to the new naming. We tried to time this change to the point in time where the amount of pending patches is the smallest: the end of the merge window. Namespace clashes were fixed up in a preparatory patch - and some stylistic fallout will be fixed up in a subsequent patch. ( NOTE: 'counters' are still the proper terminology when we deal with hardware registers - and these sed scripts are a bit over-eager in renaming them. I've undone some of that, but in case there's something left where 'counter' would be better than 'event' we can undo that on an individual basis instead of touching an otherwise nicely automated patch. ) Suggested-by: Stephane Eranian <eranian@google.com> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Paul Mackerras <paulus@samba.org> Reviewed-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: David Howells <dhowells@redhat.com> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "David S.

This led to linker script for each arch implementing its own /DISCARD/ definition, which makes maintaining tedious and adding new entries error-prone. This patch makes all linker scripts to move discard definitions to the end of the linker script and use the common DISCARDS macro. As ld uses the first matching section definition, archs can include default discarded sections by including them earlier in the linker script. ia64 is notable because it first throws away some ia64 specific subsections and then include the rest of the sections into the final image, so those sections must be discarded before the inclusion. defconfig compile tested for x86, x86-64, powerpc, powerpc64, ia64, alpha, sparc, sparc64 and s390.

| | * | microblaze: Makefile cleanupSam Ravnborg2009-07-272-18/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reviewed the Makefile on request by Michal and this is the resulting changes. o Use ':=' for assignmnet so we do not re-evaluate for each use o Use $(shell echo xxx) to remove "" o Replaced CFLAGS_KERNEL with KBUILD_CFLAGS The settings are equally relevant for modules and the linked kernel o Dropped LDFLAGS_BLOB - it is no longer used o Refactored assignmnets to libs-y and core-y o Use MMU for the MMU specific extension. "MMUEXT" was hurting my eyes and I did not wanted it spread to m68k Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Michal Simek <monstr@monstr.eu>

| | | | | | | | | | | | | | | | | | | | | | | | For example reiserfs use this relocation type. Signed-off-by: Michal Simek <monstr@monstr.eu>
| | * | microblaze: Get module loading workingJohn Williams2009-07-271-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New reloc type R_MICROBLAZE_32_PCREL_LO requires a null handler (no work to do). Remove legacy hack for broken linker pre gcc-4.1.1, that required us to extract an offset from the code, add it to the addend, then rewrite the instruction. Fixup the invalid reloc type error output. Boot tested with the xilinx_emaclite ethernet driver. Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
| | * | microblaze: remove sys_ipcArnd Bergmann2009-07-272-100/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ipc system call is now unused in microblaze, as the system call table points directly to the indidual system calls for IPC. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
| | * | microblaze: Support unaligned address for put/get_user macrosMichal Simek2009-07-272-64/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add support for cases where load/store instruction in put/get_user macro gets unaligned pointer to data and this address is not valid. I prevent all cases which can failed. I had to disable first stage of unaligned handler which is used only for noMMU kernel and the whole work is done when interrupt is enabled. You have enable HW support for detect unaligned access in Microblaze. This patch fixed three LTP tests: getpeername01, getsockname01, socketpair01 Signed-off-by: Michal Simek <monstr@monstr.eu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling fixup when we are in kernel mode. This prevent fault for copy_to/from_user. This fault was find thanks to writev01/03/04 LTP tests. Signed-off-by: Michal Simek <monstr@monstr.eu>
