* powerpc/40x: Convert AMCC Makalu board to ppc40x_simpleJosh Boyer2009-06-045-83/+61
| | | | | | | | This cleans up the makalu board port to use the ppc40x_simple platform support. Tested-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
* powerpc/4xx: Sequoia: Enable NAND supportStefan Roese2009-06-042-37/+94
| | | | | | | | | Now that the 4xx NAND driver is available again in arch/powerpc, let's enable it on Sequoia. This patch also disables the early debug messages (CONFIG_PPC_EARLY_DEBUG) in the Sequoia defconfig. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

| | | | | | | | | | | | | | | | | | The i2c-ibm_iic driver printed messages in an odd order that seemed to list devices before the driver was probed. Here is an example: at24 0-0052: 512 byte 24c04 EEPROM (writable) ibm-iic ef600700.i2c: using standard (100 kHz) mode ad7414 0-004a: chip found This changes the order to print the i2c driver message before scanning for devices so that the logs show the driver, then the devices.

| | | | | | | | | | The single board defconfig files were missed during the cleanup of CONFIG_PCI_LEGACY in the multi-board config files. This disables the option for the single board configs, as it isn't used by anything for these boards.

* powerpc/pci: Fix annotation of pcibios_claim_one_busStephen Rothwell2009-06-021-2/+1
| | | | | | | | | | | | | | | | | It was __devinit, but it is also within a CONFIG_HOTPLUG guarded section of code, so the __devinit does nothing but cause the following warning: WARNING: vmlinux.o(.text+0x107a8): Section mismatch in reference from the function pcibios_finish_adding_to_bus() to the function .devinit.text:pcibios_claim_one_bus() The function pcibios_finish_adding_to_bus() references the function __devinit pcibios_claim_one_bus(). This is often because pcibios_finish_adding_to_bus lacks a __devinit annotation or the annotation of pcibios_claim_one_bus is wrong.

* powerpc: Convert RTAS event scan from kernel thread to workqueueAnton Blanchard2009-06-021-38/+38
| | | | | | | | | | | | | | | | | | | | | | RTAS event scan has to run across all cpus. Right now we use a kernel thread and set_cpus_allowed but in doing so we wake up the previous cpu unnecessarily. Some ftrace output shows this: previous cpu (2): [002] 7.022331: sched_switch: task swapper:0 [140] ==> rtasd:194 [120] [002] 7.022338: sched_switch: task rtasd:194 [120] ==> migration/2:9 [0] [002] 7.022344: sched_switch: task migration/2:9 [0] ==> swapper:0 [140] next cpu (3): [003] 7.022345: sched_switch: task swapper:0 [140] ==> rtasd:194 [120] [003] 7.022371: sched_switch: task rtasd:194 [120] ==> swapper:0 [140] We can use schedule_delayed_work_on and avoid the unnecessary wakeup.

This fixes it by using more classic PTE accessors and automatically locating the area for consistent memory, carving an appropriate hole in the kernel virtual address space, leaving only the size of that area as a Kconfig option. It also brings some dma-mask related fixes from the ARM implementation which was almost identical initially but grew its own fixes. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

While it was a good idea to try to use the mm/vmalloc.c allocator instead of our own (in fact, ours is itself a dup on an old variant of the vmalloc one), unfortunately, the approach is terminally busted since dma_alloc_coherent() can be called at interrupt time or in atomic contexts and there's little chances we'll make the code in mm/vmalloc.c cope with\ that :-( Until we can get the generic code to forbid that idiocy and fix all drivers abusing it, we pretty much have no choice but revert to our custom virtual space allocator. There's also a problem with SMP safety since freeing such mapping would require an IPI which cannot be done at interrupt time. However, right now, I don't think we support any platform that is both SMP and has non-coherent DMA (don't laugh, I know such things do exist !) so we can sort that out later.

The kernel image is one statically linked object and only uses two relocation types - R_386_PC32 and R_386_32, of the two only the latter needs massaging during kernel relocation and thus handled by relocs. R_386_PC32 is ignored and all other relocation types are considered error. When the target of a relocation resides in a discarded section, binutils doesn't throw away the relocation record but nullifies it by changing it to R_386_NONE, which unfortunately makes relocs fail. The problem was triggered by yet out-of-tree x86 stack unwind patches but given the binutils behavior, ignoring R_386_NONE is the right thing to do. The problem has been tracked down to binutils behavior by Jan Beulich.

This fixes a bug whereby the name card0-VGA-1 would be allocted to both a CRT and an SDVO connector since the SDVO connector would be initialised with type 'unknown' and hence have its type_id assigned from the wrong pool.

This is nice and fast, but won't work well if memory is fragmented, since the slab allocator works with physically contiguous memory (i.e. order > 2 allocations are likely to fail fairly early after booting and doing some work). This patch works around the issue by falling back to vmalloc for >PAGE_SIZE allocations. This is ugly, but much less work than chaining a bunch of pages together by hand (suprisingly there's not a bunch of generic kernel helpers for this yet afaik). vmalloc space is somewhat precious on 32 bit kernels, but our allocations shouldn't be big enough to cause problems, though they're routinely more than a page. Note that this patch doesn't address the unchecked alloc-based-on-ioctl-args in GEM; that needs to be fixed in a separate patch. Also, I've deliberately ignored the DRM's "area" junk. I don't think anyone actually uses it anymore and I'm hoping it gets ripped out soon. [Updated: removed size arg to new free function. We could unify the free functions as well once the DRM mem tracking is ripped out.] fd.o bug #20152 (part 1/3) Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>

This led to the allocation of too small cpu buffers. This patch recalculates the buffer size in bytes taking also the ring_buffer_event header size into account.
