* [POWERPC] Do not write virq back to PCI config spaceMichal Ostrowski2007-01-242-2/+0
| | | | | | | | | | | | | | | | - Drivers will not rely on the PCI config space value, as they've already been conditioned to rely on the irq field in "struct pci_dev". - The virq value may not be < 256 as it has been remapped. - The PCI config space should reflect the hardware configuration, which is not being changed. We are only creating a virtual irq mapping that exists in the kernel only. One would never expect the PCI hardware to generate the "virq" interrupt.

* [POWERPC] Fix broken DMA on non-LPAR pSeriesLinas Vepstas2007-01-221-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It appears that the iommu table address is never stored, and thus never found, on non-lpar systems. Thus, for example, during boot: <7>[ 93.067916] PCI: Scanning bus 0001:41 <7>[ 93.068542] PCI: Found 0001:41:01.0 [8086/100f] 000200 00 <7>[ 93.068550] PCI: Calling quirk c0000000007822e0 for 0001:41:01.0 <7>[ 93.069815] PCI: Fixups for bus 0001:41 <4>[ 93.070167] iommu: Device 0001:41:01.0 has no iommu table <7>[ 93.070251] PCI: Bus scan for 0001:41 returning with max=41 No iommu table? How can that be? Well, circa line 471 of arch/powerpc/platforms/pseries/iommu.c we see the code: while (dn && PCI_DN(dn) && PCI_DN(dn)->iommu_table == NULL) dn = dn->parent; and a few lines later is the surprising print statement about the missing table. Seems that this loop ran unto the end, never once finding a non-null PCI_DN(dn)->iommu_table. The problem can be found a few lines earlier: it sems that the value of PCI_DN(dn)->iommu_table is never ever set. Thus, the patch sets it. The patch was tested on a Power4 system running in full system partition mode, which is where I saw the problem. It works; I've not done any wider testing. Had a brief discussion on this on irc.

| | | | | | | | | | | The mmio nvram driver (used by cell only atm) isn't properly parsing the device-tree, meaning that nvram isn't found correctly on the new Cell blades.

* [PATCH] Change cpu_up and co from __devinit to __cpuinitGautham R Shenoy2007-01-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Compiling the kernel with CONFIG_HOTPLUG = y and CONFIG_HOTPLUG_CPU = n with CONFIG_RELOCATABLE = y generates the following modpost warnings WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between '_cpu_up' (at offset 0xc0141b7d) and 'cpu_up' WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between '_cpu_up' (at offset 0xc0141b9c) and 'cpu_up' WARNING: vmlinux - Section mismatch: reference to .init.text:__cpu_up from .text between '_cpu_up' (at offset 0xc0141bd8) and 'cpu_up' WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between '_cpu_up' (at offset 0xc0141c05) and 'cpu_up' WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between '_cpu_up' (at offset 0xc0141c26) and 'cpu_up' WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between '_cpu_up' (at offset 0xc0141c37) and 'cpu_up' This is because cpu_up, _cpu_up and __cpu_up (in some architectures) are defined as __devinit AND __cpu_up calls some __cpuinit functions. Since __cpuinit would map to __init with this kind of a configuration, we get a .text refering .init.data warning. This patch solves the problem by converting all of __cpu_up, _cpu_up and cpu_up from __devinit to __cpuinit. The approach is justified since the callers of cpu_up are either dependent on CONFIG_HOTPLUG_CPU or are of __init type. Thus when CONFIG_HOTPLUG_CPU=y, all these cpu up functions would land up in .text section, and when CONFIG_HOTPLUG_CPU=n, all these functions would land up in .init section.

* [POWERPC] Fix bugs in the hypervisor call stats codeAnton Blanchard2007-01-092-5/+5
| | | | | | | | | | | | | | | | There were a few issues with the HCALL_STATS code: - PURR cpu feature checks were backwards - We iterated one entry off the end of the hcall_stats array - Remove dead update_hcall_stats() function prototype I noticed one thing while debugging, and that is we call H_ENTER (to set up the MMU hashtable in early init) before we have done the cpu fixups. This means we will execute the PURR SPR reads even on a CPU that isnt capable of it. I wonder if we can move the CPU feature fixups earlier.

This patch provides an EMIT_BUG_ENTRY macro for use in assembly code, and uses it in entry_64.S. Tested with CONFIG_DEBUG_BUGVERBOSE on ppc64 but not without -- I tried to turn it off but it wouldn't go away; I suspect Aunt Tillie probably needed it.

I'm not sure if these assumptions came about because they were valid with earlier versions of the get_unmapped_area() path, or if it was always broken.

* | [POWERPC] Fix register save area alignment for swapcontext syscallPaul Mackerras2006-12-201-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 32-bit processes, the getcontext side of the swapcontext system call (i.e. the saving of the context when the first argument is non-NULL) has to set the ctx->uc_mcontext.uc_regs pointer to the place where it saves the registers. Which it does, but it doesn't ensure that the pointer is 16-byte aligned. 16-byte alignment is needed because the Altivec/VMX registers are saved in there, and they need to be on a 16-byte boundary. This fixes it by ensuring the appropriate alignment of the pointer. This issue was pointed out by Jakub Jelinek. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | The Efika matches chrp_probe() too, so put its own probe first to make sure we get it right in a multiplatform build. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* | [POWERPC] Fix build of cell zImage.initrdBenjamin Herrenschmidt2006-12-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | The patch adding support for zImage.ps3 didn't add a zImage.initrd.ps3 target causing builds of zImage.initrd to fail when ps3 is included in the .config. The current method of generating ps3 images doesn't support initrd's yet, so we create a dummy target that only displays a warning message instead.
