| * | ppc64 iSeries: Update create_pte_mapping to replace iSeries_bolt_kernel()Michael Ellerman2005-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | early_setup() calls htab_initialize() which is similar, but not identical to iSeries_bolt_kernel(). On iSeries the Hypervisor has already inserted some ptes for us, and we simply have to detect that and bolt them. iSeries_hpte_bolt_or_insert() implements that logic. For the case of a non-existing pte we just call iSeries_hpte_insert(). This appears to work, although it's not entirely equivalent to the old code in iSeries_make_pte() which panicked if we got a secondary slot. Not sure if that's important. Finally we call iSeries_hpte_bolt_or_insert() from create_pte_mapping(), which is called from htab_initialize() for each lmb region.

| * | ppc46 iSeries: Make some generic irq code compile for iSeriesMichael Ellerman2005-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to call finish_device_tree() on iSeries we need to define virt_irq_create_mapping(). We also need to set ppc64_interrupt_controller to something other than zero. If we want to do interrupt setup via the device tree on iSeries this code will need some serious work, but it's harmless to have it there as long as the nodes in the iSeries device tree don't cause it to be invoked.

| * [PATCH] ppc64: SMU driver update & i2c supportBenjamin Herrenschmidt2005-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SMU is the "system controller" chip used by Apple recent G5 machines including the iMac G5. It drives things like fans, i2c busses, real time clock, etc... The current kernel contains a very crude driver that doesn't do much more than reading the real time clock synchronously. This is a completely rewritten driver that provides interrupt based command queuing, a userland interface, and an i2c/smbus driver for accessing the devices hanging off the SMU i2c busses like temperature sensors. This driver is a basic block for upcoming work on thermal control for those machines, among others.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent iommu fix broke booting on some POWER4 and POWER5 LPAR boxes. It looks like we have been calling the non LPAR iommu_dev_setup on LPAR machines for a while. The recent iommu fix caused that code path to fail. It looks like we just need to hook up the devices iommu_table to the parents one, so do that instead of calling iommu_dev_setup_pSeries and crossing the streams.

| * [PATCH] PPC64: Fix boot for some pre-POWER4 systemsOlof Johansson2005-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some RS64 systems (such as F80) have non-python host bridges with EADS. However, they have two EADS with 4 buses each under them, so the old logic that assumed no more than 7 busses per PHB failed miserably. Big thanks to Olaf Hering for helping me test this, he's got one of the few machines that broke from the previous logic. Also, to be a bit smarter at detecting the need for a PHB-level IOMMU table by checking for the presence of an ISA bus. Only PHBs with ISA bridges should need the PHB-level table.

* [PATCH] error path in setup_arg_pages() misses vm_unacct_memory()Hugh Dickins2005-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Pavel Emelianov and Kirill Korotaev observe that fs and arch users of security_vm_enough_memory tend to forget to vm_unacct_memory when a failure occurs further down (typically in setup_arg_pages variants). These are all users of insert_vm_struct, and that reservation will only be unaccounted on exit if the vma is marked VM_ACCOUNT: which in some cases it is (hidden inside VM_STACK_FLAGS) and in some cases it isn't. So x86_64 32-bit and ppc64 vDSO ELFs have been leaking memory into Committed_AS each time they're run. But don't add VM_ACCOUNT to them, it's inappropriate to reserve against the very unlikely case that gdb be used to COW a vDSO page - we ought to do something about that in do_wp_page, but there are yet other inconsistencies to be resolved. The safe and economical way to fix this is to let insert_vm_struct do the security_vm_enough_memory check when it finds VM_ACCOUNT is set. And the MIPS irix_brk has been calling security_vm_enough_memory before calling do_brk which repeats it, doubly accounting and so also leaking. Remove that, and all the fs and arch calls to security_vm_enough_memory: give it a less misleading name later on.
