* [POWERPC] Fix xics set_affinity codeAnton Blanchard2007-10-01
| | | | | | | | | | | | | | | | | | | On a POWER6 machine running 2.6.23-rc8 I sometimes see the following error: xics_set_affinity: No online cpus in the mask 00000000,00000000,00000000,00000001 for irq 20 In a desperate attempt to get a changelog entry in 2.6.23, I took a look into it. It turns out we are passing a real and not a virtual irq into get_irq_server. This works for the case where hwirq < NR_IRQS and we set virq = hwirq. In my case however hwirq = 590082 and we try and access irq_desc[590082], slightly past the end at 512 entries. Lucky we ship lots of memory with our machines.

| | | | | | | | | | | Setup dr_mode for USB-DR to peripheral as the default (host mode) doesn't make much sense for the mini-AB connector on the ITX board. Peripheral mode is preferable to OTG as the fsl_usb2_udc.c driver doesn't yet properly support it.

* [POWERPC] Ensure FULL_REGS on execRoland McGrath2007-09-25
| | | | | | | | | | | | | | | When PTRACE_O_TRACEEXEC is used, a ptrace call to fetch the registers at the PTRACE_EVENT_EXEC stop (PTRACE_PEEKUSR) will oops in CHECK_FULL_REGS. With recent versions, "gdb --args /bin/sh -c 'exec /bin/true'" and "run" at the (gdb) prompt is sufficient to produce this. I also have written an isolated test case, see https://bugzilla.redhat.com/show_bug.cgi?id=301791#c15. This change fixes the problem by clearing the low bit of pt_regs.trap in start_thread so that FULL_REGS is true again. This is correct since all of the GPRs that "full" refers to are cleared in start_thread. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | With the I/O space rewrite by BenH, the legacy_serial serial_dev_init() initcall is now called before I/O space is setup, but it's dependent on it being available. Since there's no way to make dependencies between initcalls, we'll just have to move it to device_initcall().

* [POWERPC] spu_manage: fix spu_unit_number for celleb device treeChristian Krafft2007-08-29
| | | | | | | | | | | | | | | | | | | | This fixes a regression introduced with 2.6.23-rc4 after on some confusion about the device tree interfaces. IBM QS21 device trees provide "physical-id", so we changed the code to run on that and remain compatible with all IBM machines. However, the Toshiba Celleb device tree provides the "unit-id" property, which was in the Linux code, but never used in this way on IBM hardware. Legacy device tree used the reg property for the physical id of an spe. This patch fixes find_spu_unit_number to look for the spu id in that order. The length is checked to avoid misinterpretation in case the attributes unit-id or reg do not contain the id.

| | | | | | | | | | | | | | When we flush register state for FP, Altivec, or SPE in flush_*_to_thread we need to respect the task_struct that the caller has passed to us. Most cases we are called with current, however sometimes (ptrace) we may be passed a different task_struct. This showed up when using gdbserver debugging a simple program that used floating point.

It turns out that the part of that commit that aimed to ensure that we created an SLB entry for the kernel stack on secondary CPUs when starting the CPU didn't achieve its aim, and in fact caused a regression, because get_paca()->kstack is not initialized at the point where slb_initialize is called.

So, we implement TLB invalidates by explicitly searching the TLB with tlbsx., then clobbering the relevant entry, if any. Unfortunately the PID for the search needs to be stored in the MMUCR register, which is also used by the TLB miss handler. Interrupts were enabled in _tlbie(), so an interrupt between loading the MMUCR and the tlbsx could cause incorrect search results, and thus a failure to invalide TLB entries which needed to be invalidated. This fixes the problem in both arch/ppc and arch/powerpc by inhibiting interrupts (even critical and debug interrupts) across the relevant instructions.

* | [POWERPC] Remove unused code causing a compile warningBecky Bruce2007-08-15
| | | | | | | | | | | | | | | | | | | | AFAICT, nobody is using ft_ordered(), and it causes a build warning to be generated. This patch cleans that up by removing the function and the commented-out code that calls it.

* | [POWERPC] cell: Fix errno for modular spufs_create with invalid neighbourJeremy Kerr2007-08-15
|/ | | | | | | | | | | | At present, spu_create with an invalid neighbo(u)r will return -ENOSYS, not -EBADF, but only when spufs.o is built as a module. This change adds the appropriate errno, making the behaviour the same as the built-in case.

* [POWERPC] Fix size check for hugetlbfsBenjamin Herrenschmidt2007-08-10
| | | | | | | | | | | | My "slices" address space management code that was added in the 2.6.22 implementation of get_unmapped_area() doesn't properly check that the size is a multiple of the requested page size. This allows userland to create VMAs that aren't a multiple of the huge page size with hugetlbfs (since hugetlbfs entirely relies on get_unmapped_area() to do that checking) which leads to a kernel BUG() when such areas are torn down.

* [POWERPC] Fix initialization and usage of dma_maskBenjamin Herrenschmidt2007-08-10
| | | | | | | | | | | | | | | powerpc has a couple of bugs in the usage of dma_masks that tend to break when drivers explicitly try to set a 32-bit mask for example. First, the code that generates the pci devices from the OF device-tree doesn't initialize the mask properly, then our implementation of set_dma_mask() was trying to validate the -previous- mask value, not the one passed in as an argument. This fixes these problems. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Revert "[POWERPC] Add 'mdio' to bus scan id list for platforms ↵Kim Phillips2007-08-10
| | | | | | | | | | | | | | | | | | | | | with QE UEC" This reverts commit 3baee955953957be5496cd28e9c544d9db214262. That commit was a mistake from the start; I added mdio type to the bus scan list early on in my ucc_geth migrate to phylib development, which is just pure wrong (the ucc_geth_mii driver creates the mii bus and the PHY layer handles PHY enumeration without translation). This follows on from commit 77926826f301fbd8ed96d3cd9ff17a5b59560dfb: Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()" which was basically trying to hide a symptom of the original mistake this revert fixes.
