* [PATCH] ppc64: support 64k pagesBenjamin Herrenschmidt2005-11-067-156/+170
| | | | | | | | | | | | | | | Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel base page size to 64K. The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently. Note that while real 64K capable HW has been tested, the current patch will not enable it yet as such hardware is not released yet, and I'm still verifying with the firmware architects the proper to get the information from the newer hypervisors.

* powerpc: Merge smp.c and smp.hPaul Mackerras2005-11-051-38/+1
| | | | | | | 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>

| * [PATCH] powerpc: always init nvram on 64-bit powermacDavid Woodhouse2005-11-031-1/+1
| | | | | | | | | | | | | | | | | | Currently there is no Kconfig symbol to indicate that we want nvram support on 64-bit kernels; it's assumed we always want it, so make the powermac setup code always initialize the pmac nvram code if 64-bit. Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [PATCH] ppc64: Fix add notifier crashesJohn Rose2005-11-031-1/+1
| | | | | | | | | | | | | | | | | | The extraction of PCI stuff from struct device_node left some false assumptions in notifier code. As a result, dynamic add crashes when non-PCI nodes are added. This patch fixes these assumptions. Signed-off-by: John Rose <johnrose@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * powerpc: Merge remaining RTAS codePaul Mackerras2005-11-034-13/+531
| | | | | | | | | | | | | | | | | | 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.

* | powerpc: Cleanup vpa codeMichael Ellerman2005-11-032-10/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | register_vpa() doesn't actually do a VPA register call it just uses the flags you pass it, so rename it to vpa_call() to be clearer. We can then define register_vpa() and unregister_vpa() which are both simple wrappers around vpa_call(). (we'll need unregister_vpa() for kexec soon) We can then cleanup vpa_init(), and because vpa_init() is only called from platforms/pseries we remove the definition in asm-ppc64/smp.h.

| * [PATCH] powerpc: Move naca.h to platforms/iseriesDavid Gibson2005-11-024-3/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | These days, the NACA only exists on iSeries. Therefore, this patch moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries. There was one file including naca.h outside of platforms/iseries - arch/ppc64/kernel/udbg_scc.c. However, that's obviously a hangover from older days. The include is not necessary, so this patch simply removes it. Built and booted on iSeries, built for G5 (which uses udbg_scc.o).

* | powerpc: exclude powerbook sleep code with CONFIG_PPC64 and CONFIG_PMPaul Mackerras2005-11-021-4/+4
| | | | | | | | | | | | | | | | | | We were getting powerbook sleep code included, and giving compile errors, with CONFIG_PM=y on a 64-bit build. This excludes that code so the kernel will compile. One day BenH will implement on sleep on the G5... Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | The nvram driver imported from the ppc code uses call_rtas, but rtas_call is the name we are using in merged code (since ppc64 used that name, and it uses far more RTAS calls than ppc32). Signed-off-by: Paul Mackerras <paulus@samba.org>

* powerpc: Fix bug arising from having multiple memory_limit variablesPaul Mackerras2005-10-311-2/+0
| | | | | | | | | | We had a static memory_limit in prom.c, and then another one defined in setup_64.c and used in numa.c, which resulted in the kernel crashing when mem=xxx was given on the command line. This puts the declaration in system.h and the definition in mem.c. This also moves the definition of tce_alloc_start/end out of setup_64.c. Signed-off-by: Paul Mackerras <paulus@samba.org>

* [PATCH] powerpc: Move xics.[ch] into platforms/pseriesDavid Gibson2005-10-285-2/+784
| | | | | | | | | | | 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.

* powerpc: Merge rtas.c into arch/powerpc/kernelPaul Mackerras2005-10-265-10/+148
| | | | | | | | | | | | | 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>
* powerpc: Merge i8259.c into arch/powerpc/sysdevPaul Mackerras2005-10-262-15/+9
| | | | | | | | | | | | 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>
* ppc: Use the indirect_pci.c from arch/powerpc/sysdevPaul Mackerras2005-10-261-0/+8
