* powerpc/fsl-booke: Add e55xx (64-bit) smp defconfigKumar Gala2010-10-142-3/+85
| | | | | | | | | | The p5020 SoC from Freescale is the first 64-bit Book-E processor and utilizes the two e5500 cores. Adding a defconfig that enables basic kernel for e5500 based processors. Also added the p5020 / e5500 support to the ppc64e defconfig. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* powerpc/fsl-booke64: Use TLB CAMs to cover linear mapping on FSL 64-bit chipsKumar Gala2010-10-146-10/+29
| | | | | | | | | | | | | | On Freescale parts typically have TLB array for large mappings that we can bolt the linear mapping into. We utilize the code that already exists on PPC32 on the 64-bit side to setup the linear mapping to be cover by bolted TLB entries. We utilize a quarter of the variable size TLB array for this purpose. Additionally, we limit the amount of memory to what we can cover via bolted entries so we don't get secondary faults in the TLB miss handlers. We should fix this limitation in the future.

* powerpc/fsl-booke: Add support for FSL Arch v1.0 MMU in setup_page_sizesKumar Gala2010-10-142-3/+54
| | | | | | | | | | | Update setup_page_sizes() to support for a MMU v1.0 FSL style MMU implementation. In such a processor, we don't have TLB0PS or EPTCFG registers (and access to these registers may cause exceptions). We need to parse the older format of TLBnCFG for page size support. Additionaly, assume since we are an FSL implementation that we have 2 TLB arrays and the second array contains the variable size pages. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* oprofile/fsl emb: Don't set MSR[PMM] until after clearing the interrupt.Scott Wood2010-10-141-7/+8
| | | | | | | | | | | | | | | | | | On an arch 2.06 hypervisor, a pending perfmon interrupt will be delivered to the hypervisor at any point the guest is running, regardless of MSR[EE]. In order to reflect this interrupt, the hypervisor has to mask the interrupt in PMGC0 -- and set MSRP[PMMP] to intercept futher guest accesses to the PMRs to detect when to unmask (and prevent the guest from unmasking early, or seeing inconsistent state). This has the side effect of ignoring any changes the guest makes to MSR[PMM], so wait until after the interrupt is clear, and thus the hypervisor should have cleared MSRP[PMMP], before setting MSR[PMM]. The counters wil not actually run until PMGC0[FAC] is cleared in pmc_start_ctrs(), so this will not reduce the effectiveness of PMM.

* powerpc: Fix invalid page flags in create TLB CAM path for PTE_64BITPaul Gortmaker2010-10-142-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There exists a four line chunk of code, which when configured for 64 bit address space, can incorrectly set certain page flags during the TLB creation. It turns out that this is code which isn't used, but might still serve a purpose. Since it isn't obvious why it exists or why it causes problems, the below description covers both in detail. For powerpc bootstrap, the physical memory (at most 768M), is mapped into the kernel space via the following path: MMU_init() | + adjust_total_lowmem() | + map_mem_in_cams() | + settlbcam(i, virt, phys, cam_sz, PAGE_KERNEL_X, 0); On settlbcam(), the kernel will create TLB entries according to the flag, PAGE_KERNEL_X. settlbcam() { ... TLBCAM[index].MAS1 = MAS1_VALID | MAS1_IPROT | MAS1_TSIZE(tsize) | MAS1_TID(pid); ^ These entries cannot be invalidated by the kernel since MAS1_IPROT is set on TLB property. ... if (flags & _PAGE_USER) { TLBCAM[index].MAS3 |= MAS3_UX | MAS3_UR; TLBCAM[index].MAS3 |= ((flags & _PAGE_RW) ? MAS3_UW : 0); } For classic BookE (flags & _PAGE_USER) is 'zero' so it's fine. But on boards like the the Freescale P4080, we want to support 36-bit physical address on it. So the following options may be set: CONFIG_FSL_BOOKE=y CONFIG_PTE_64BIT=y CONFIG_PHYS_64BIT=y As a result, boards like the P4080 will introduce PTE format as Book3E. As per the file: arch/powerpc/include/asm/pgtable-ppc32.h * #elif defined(CONFIG_FSL_BOOKE) && defined(CONFIG_PTE_64BIT) * #include <asm/pte-book3e.h> So PAGE_KERNEL_X is __pgprot(_PAGE_BASE | _PAGE_KERNEL_RWX) and the book3E version of _PAGE_KERNEL_RWX is defined with: (_PAGE_BAP_SW | _PAGE_BAP_SR | _PAGE_DIRTY | _PAGE_BAP_SX) Note the _PAGE_BAP_SR, which is also defined in the book3E _PAGE_USER: #define _PAGE_USER (_PAGE_BAP_UR | _PAGE_BAP_SR) /* Can be read */ So the possibility exists to wrongly assign the user MAS3_U<RWX> bits to kernel (PAGE_KERNEL_X) address space via the following code fragment: if (flags & _PAGE_USER) { TLBCAM[index].MAS3 |= MAS3_UX | MAS3_UR; TLBCAM[index].MAS3 |= ((flags & _PAGE_RW) ? MAS3_UW : 0); } Here is a dump of the TLB info from Simics with the above code present: ------ L2 TLB1 GT SSS UUU V I Row Logical Physical SS TLPID TID WIMGE XWR XWR F P V ----- ----------------- ------------------- -- ----- ----- ----- --- --- - - - 0 c0000000-cfffffff 000000000-00fffffff 00 0 0 M XWR XWR 0 1 1 1 d0000000-dfffffff 010000000-01fffffff 00 0 0 M XWR XWR 0 1 1 2 e0000000-efffffff 020000000-02fffffff 00 0 0 M XWR XWR 0 1 1 Actually this conditional code was used for two legacy functions: 1: support KGDB to set break point. KGDB already dropped this; now uses its core write to set break point. 2: io_block_mapping() to create TLB in segmentation size (not PAGE_SIZE) for device IO space. This use case is also removed from the latest PowerPC kernel. However, there may still be a use case for it in the future, like large user pages, so we can't remove it entirely. As an alternative, we match on all bits of _PAGE_USER instead of just any bits, so the case where just _PAGE_BAP_SR is set can't sneak through. With this done, the TLB appears without U having XWR as below: ------- L2 TLB1 GT SSS UUU V I Row Logical Physical SS TLPID TID WIMGE XWR XWR F P V ----- ----------------- ------------------- -- ----- ----- ----- --- --- - - - 0 c0000000-cfffffff 000000000-00fffffff 00 0 0 M XWR 0 1 1 1 d0000000-dfffffff 010000000-01fffffff 00 0 0 M XWR 0 1 1 2 e0000000-efffffff 020000000-02fffffff 00 0 0 M XWR 0 1 1 Signed-off-by: Tiejun Chen <tiejun.chen@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* powerpc/pseries/xics: Use cpu_possible_mask rather than cpu_all_maskNishanth Aravamudan2010-10-131-1/+1
| | | | | | | | | | | | | | Current firmware only allows us to send IRQs to the first processor or all processors. We currently check to see if the passed in mask is equal to the all_mask, but the firmware is only considering whether the request is for the equivalent of the possible_mask. Thus, we think the request is for some subset of CPUs and only assign IRQs to the first CPU (on systems without irqbalance running) as evidenced by /proc/interrupts. By using possible_mask instead, we account for this and proper interleaving of interrupts occurs.

| | * MIPS: Calculate VMLINUZ_LOAD_ADDRESS based on the length of vmlinux.binShmulik Ladkani2010-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix VMLINUZ_LOAD_ADDRESS calculation to be based on the length of vmlinux.bin, the actual uncompressed kernel binary. Previously it was based on the length of KBUILD_IMAGE (the unstripped ELF vmlinux), which is bigger than vmlinux.bin. As a result, vmlinuz was loaded into a memory address higher then actually needed - a problem for small memory platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function prom_init_cmdline() references the variable __initdata arcs_cmdline. The function prom_get_ethernet_addr() references the variable __initdata arcs_cmdline. Annotate prom_init_cmdline() as __init, unexport and annotate prom_get_ethernet_addr() since it's no longer called from within driver code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Architectures need to set ARCH_DMA_MINALIGN to the minimum DMA alignment (commit a6eb9fe105d5de0053b261148cee56c94b4720ca). Defining ARCH_KMALLOC_MINALIGN doesn't work anymore.

| | * MIPS: N32: Fix getdents64 syscall for n32Bernhard Walle2010-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 31c984a5acabea5d8c7224dc226453022be46f33 introduced a new syscall getdents64. However, in the syscall table, the new syscall still refers to the old getdents which doesn't work. The problem appeared with a system that uses the eglibc 2.12-r11187 (that utilizes that new syscall) is very confused. The fix has been tested with that eglibc version.
