2005-11-05powerpc: Merge smp.c and smp.hPaul Mackerras1-1/+0
This also moves setup_cpu_maps to setup-common.c (calling it smp_setup_cpu_maps) and uses it on both 32-bit and 64-bit. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-04powerpc: Merge smp-tbsync.c (the generic timebase sync routine)Paul Mackerras1-5/+0

Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-11-03powerpc: Merge remaining RTAS codePaul Mackerras1-3/+1
This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since cell wants them as well as pseries (and chrp can use rtas-proc.c too, at least in principle). rtas_fw.c is gone, with its bits moved into rtas_flash.c and rtas.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-01[PATCH] powerpc: Merge bitops.hDavid Gibson1-1/+1
Here's a revised version. This re-introduces the set_bits() function from ppc64, which I removed because I thought it was unused (it exists on no other arch). In fact it is used in the powermac interrupt code (but not on pSeries). - We use LARXL/STCXL macros to generate the right (32 or 64 bit) instructions, similar to LDL/STL from ppc_asm.h, used in fpu.S - ppc32 previously used a full "sync" barrier at the end of test_and_*_bit(), whereas ppc64 used an "isync". The merged version uses "isync", since I believe that's sufficient. - The ppc64 versions of then minix_*() bitmap functions have changed semantics. Previously on ppc64, these functions were big-endian (that is bit 0 was the LSB in the first 64-bit, big-endian word). On ppc32 (and x86, for that matter, they were little-endian. As far as I can tell, the big-endian usage was simply wrong - I guess no-one ever tried to use minixfs on ppc64. - On ppc32 find_next_bit() and find_next_zero_bit() are no longer inline (they were already out-of-line on ppc64). - For ppc64, sched_find_first_bit() has moved from mmu_context.h to the merged bitops. What it was doing in mmu_context.h in the first place, I have no idea. - The fls() function is now implemented using the cntlzw instruction on ppc64, instead of generic_fls(), as it already was on ppc32. - For ARCH=ppc, this patch requires adding arch/powerpc/lib to the arch/ppc/Makefile. This in turn requires some changes to arch/powerpc/lib/Makefile which didn't correctly handle ARCH=ppc. Built and running on G5.

2005-11-01[PATCH] powerpc: move arch/ppc64/kernel/bpa* to arch/powerpc/platforms/cellArnd Bergmann1-3/+0
This patch simply moves files over to arch/powerpc without making any changes to them. Signed-off-by: Arnd Bergmann <arndb@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-01[PATCH] powerpc: move mmio_nvram.c over to arch/powerpcArnd Bergmann1-1/+1
The nvram code formally known as bpa_nvram.c is rather generic really, so it is quite likely to be useful to future boards not based on cell. This patch puts it into arch/powerpc/sysdev. Signed-off-by: Arnd Bergmann <arndb@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-01[PATCH] powerpc: Rename BPA to CellArnd Bergmann1-1/+1
The official name for BPA is now CBEA (Cell Broadband Engine Architecture). This patch renames all occurences of the term BPA to 'Cell' for easier recognition. Signed-off-by: Arnd Bergmann <arndb@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-28[PATCH] powerpc: Move xics.[ch] into platforms/pseriesDavid Gibson1-2/+0
This patch moves the XICS interrupt controller code into the platforms/pseries directory, since it only appears on pSeries machines. If it ever appears on some other machine we can move it to sysdev, although xics.c itself will need a bunch of changes in that case to remove pSeries specific assumptions.

2005-10-28ppc64: use the merged syscall tableStephen Rothwell1-1/+1
This allows us to also use entry_64.S from the merged tree and reverts the setup_64.c part of fda262b8978d0089758ef9444508434c74113a61. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2005-10-27[PATCH] ppc64: remove arch/ppc64/kernel/setup.cPaul Mackerras1-1/+1
and use setup_64.c from the merged tree instead. The only difference between them was the code to set up the syscall maps. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-26powerpc: Merge rtas.c into arch/powerpc/kernelPaul Mackerras1-1/+1
This splits arch/ppc64/kernel/rtas.c into arch/powerpc/kernel/rtas.c, which contains generic RTAS functions useful on any CHRP platform, and arch/powerpc/platforms/pseries/rtas-fw.[ch], which contain some pSeries-specific firmware flashing bits. The parts of rtas.c that are to do with pSeries-specific error logging are protected by a new CONFIG_RTAS_ERROR_LOGGING symbol. The inclusion of rtas.o is controlled by the CONFIG_PPC_RTAS symbol, and the relevant platforms select that. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-26powerpc: Merge i8259.c into arch/powerpc/sysdevPaul Mackerras1-1/+1
This changes the parameters for i8259_init so that it takes two parameters: a physical address for generating an interrupt acknowledge cycle, and an interrupt number offset. i8259_init now sets the irq_desc[] for its interrupts; all the callers were doing this, and that code is gone now. This also defines a CONFIG_PPC_I8259 symbol to select i8259.o for inclusion, and makes the platforms that need it select that symbol. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-26[PATCH] powerpc: Move ras.c into arch/powerpc/platforms/pseriesMichael Ellerman1-1/+1
ras.o is only built for CONFIG_PPC_PSERIES, so move it into arch/powerpc/platforms/pseries. Update Makefiles to suit. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-24powerpc: Merge arch/ppc64/kernel/vio.c into arch/powerpc/kernel/vio.cStephen Rothwell1-1/+0
Merge arch/ppc64/kernel/vio.c into arch/powerpc/kernel/vio.c, update the Makefiles to make it work, and make ARCH=ppc64 still work. Michael's version put vio.c in arch/powerpc/sysedv but after consolting Paulus, this one puts it in arch/powerpc/kernel.

2005-10-22ppc64: Use arch/powerpc/platforms/powermac for powermac build.Paul Mackerras1-8/+2
This switches the ARCH=ppc64 build to use arch/powerpc/platforms/powermac instead of arch/ppc64/kernel/pmac*, and deletes the latter set of files. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20ppc64: Use the merged mpic.cPaul Mackerras1-2/+1
This means we now compile in arch/powerpc/sysdev for ARCH=ppc64. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20[PATCH] powerpc: Merge ppc64 pmc.[ch] with ppc32 perfmon.[ch]David Gibson1-1/+1
This patches the ppc32 and ppc64 versions of the headers and .c files with helper functions for manipulating the performance counting hardware. As a side effect, it removes use of the term "perfmon" from ppc32, thus avoiding confusion with the unrelated performance counter interface from HP Labs also called "perfmon". Built, but not booted, for g5, pSeries, iSeries, and 32-bit Powermac with both ARCH=powerpc and ARCH=ppc{,64} as appropriate.

2005-10-20powerpc: Merge time.c and asm/time.h.Paul Mackerras1-1/+1
We now use the merged time.c for both 32-bit and 64-bit compilation with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32. This removes setup_default_decr (folds its function into time_init) and moves wakeup_decrementer into time.c. This also makes an asm-powerpc/rtc.h. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20powerpc: Move ptrace32.c from arch/ppc64 to arch/powerpcPaul Mackerras1-1/+1

2005-10-10powerpc: Get 64-bit configs to compile with ARCH=powerpcPaul Mackerras1-7/+57
This is a bunch of mostly small fixes that are needed to get ARCH=powerpc to compile for 64-bit. This adds setup_64.c from arch/ppc64/kernel/setup.c and locks.c from arch/ppc64/lib/locks.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: move lparmap.c to arch/powerpc/kernelPaul Mackerras1-2/+2

Use idle_power4.S from ppc64 as we are not going to support 32 bit power4 in the merged tree. Merge ppc64 traps.c into powerpc traps.c: use ppc64 versions of exception routine names (as they don't have StudlyCaps) make all the versions if die() have the same prototype Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
