| * powerpc: unbreak iSeries compilation againPaul Mackerras2006-01-092-1/+5
| | | | | | | | | | | | | | We don't set CONFIG_PPC_MULTIPLATFORM on iSeries (yet). Avoid compiling in the prom_init stuff on iSeries. Signed-off-by: Paul Mackerras <paulus@samba.org>
| * powerpc: set CONFIG_PPC_OF=y always for ARCH=powerpcPaul Mackerras2006-01-092-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | The CONFIG_PPC_OF symbol is used to mean that the firmware device tree access functions are available. Since we always have a device tree with ARCH=powerpc, make CONFIG_PPC_OF always Y for ARCH=powerpc. This fixes some compile errors reported by Kumar Gala, but in a different way to his patch. This also makes prom_parse.o be compiled only if CONFIG_PPC_OF so that non-OF ARCH=ppc platforms will compile. Signed-off-by: Paul Mackerras <paulus@samba.org>

| * [PATCH] ppc64: fix time syscallAnton Blanchard2006-01-092-29/+1
| | | | | | | | | | | | | | | | | | | | | | | | ppc64 has its own version of sys_time. It looks pretty scary, touching a whole bunch of variables without any locking or memory ordering. In fact, a recent bugreport has shown it can actually go backwards. Time to remove it and just use the generic sys_time, which is implemented on top of do_gettimeofday.

| * [PATCH] powerpc: Replace VMALLOCBASE with VMALLOC_STARTDavid Gibson2006-01-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ppc64, we independently define VMALLOCBASE and VMALLOC_START to be the same thing: the start of the vmalloc() area at 0xd000000000000000. VMALLOC_START is used much more widely, including in generic code, so this patch gets rid of the extraneous VMALLOCBASE. This does require moving the definitions of region IDs from page_64.h to pgtable.h, but they don't clearly belong in the former rather than the latter, anyway. While we're moving them, clean up the definitions of the REGION_IDs: - Abolish REGION_SIZE, it was only used once, to define REGION_MASK anyway - Define the specific region ids in terms of the REGION_ID() macro. - Define KERNEL_REGION_ID in terms of PAGE_OFFSET rather than KERNELBASE. It amounts to the same thing, but conceptually this is about the region of the linear mapping (which starts at PAGE_OFFSET) rather than of the kernel text itself (which is at KERNELBASE).

| | | | | | | | | | | | | | | | | | | | | | | | | | This adds some very basic support for the new machines, including the Quad G5 (tested), and other new dual core based machines and iMac G5 iSight (untested). This is still experimental ! There is no thermal control yet, there is no proper handing of MSIs, etc.. but it boots, I have all 4 cores up on my machine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a few places where we need to fix things up for the kernel to work if it's linked at 32MB: - platforms/powermac/smp.c To start secondary cpus on pmac we patch the reset vector, which is fine. Except if we're above 32MB we don't have enough bits for an absolute branch, it needs to relative. - kernel/head_64.s - A few branches in the cpu hold code need to load the full target address and do a bctr. - after_prom_start needs to load PHYSICAL_START as the dest address, not 0. - The exception prolog needs to load the low word of the target adddress, not just the low halfword. - Fixup handling of the initial stab address. - kernel/setup_64.c smp_release_cpus() needs to write 1 to the spinloop flag near 0, not 32 MB.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch separates usage of KERNELBASE and PAGE_OFFSET. I haven't looked at any of the PPC32 code, if we ever want to support Kdump on PPC we'll have to do another audit, ditto for iSeries. This patch makes PAGE_OFFSET the constant, it'll always be 0xC * 1 gazillion for 64-bit. To get a physical address from a virtual one you subtract PAGE_OFFSET, _not_ KERNELBASE. KERNELBASE is the virtual address of the start of the kernel, it's often the same as PAGE_OFFSET, but _might not be_.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch unifies udbg for both ppc32 and ppc64 when building the merged achitecture. xmon now has a single "back end". The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.

| * [PATCH] powerpc: serial port discovery (#2)Benjamin Herrenschmidt2006-01-098-321/+567
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the discovery of legacy serial ports to a separate file, makes it common to ppc32 and ppc64, and reworks it to use the new OF address translators to get to the ports early. This new version can also detect some PCI serial cards using legacy chips and will probably match those discovered port with the default console choice. Only ppc64 gets udbg still yet, unifying udbg isn't finished yet. It also adds some speed-probing code to udbg so that the default console can come up at the same speed it was set to by the firmware.
