2005-09-21[PATCH] ppc64: Build zImage.vmode for G5Benjamin Herrenschmidt
zImage.vmode was recently added. It's a version of zImage in which the ELF note section used by open firmware indicates that it requires a virtual mode instance of OF instead of real mode. This allows it to work with Apple OF, and thus is directly bootable (or netbootable) from OF command line. (Unfortunately, pSeries OF sort-of requires real mode and Apple OF sort-of requires virtual mode, and both tend to be unhappy if no notes section specifies the mode at all). However, we forgot to add zImage.vmode to the default G5 build. This fixes it.

2005-09-21[PATCH] PPC64: Fix boot for some pre-POWER4 systemsOlof Johansson
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.

2005-09-21[PATCH] ppc64: Fix PCI flags when using OF device treePaul Mackerras
My code to set up the PCI tree from the Open Firmware device tree was setting IORESOURCE_* flags on the resources for the devices, but not the PCI_BASE_ADDRESS_* flags. This meant that some drivers misbehaved, and /proc/pci showed the wrong types for the resources. This fixes it.

2005-09-14[PATCH] error path in setup_arg_pages() misses vm_unacct_memory()Hugh Dickins
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.

2005-09-13[PATCH] ppc64: Make eeh_init function againPaul Mackerras
My patch "Separate pci bits out of struct device_node" (commit 1635317facea3094ddf34082cd86797efb1d9f7e) had the unfortunate side-effect that it stopped eeh_init() from working correctly. It needs the pointers set up by find_and_init_phbs(), but it was being called just before find_and_init_phbs(). That meant that we didn't enable EEH (pSeries PCI error recovery) on any devices, and that meant that on POWER5 systems, the hypervisor wouldn't let us enable memory or I/O space access to any devices, and their drivers got somewhat confused. This fixes it by moving the eeh_init call after find_and_init_phbs. Tested on a POWER5 partition. Signed-of-by: Paul Mackerras <paulus@samba.org> Signed-of-by: Linus Torvalds <torvalds@osdl.org>

2005-09-12ppc64: Set up PCI tree from Open Firmware device treePaul Mackerras
This adds code which gives us the option on ppc64 of instantiating the PCI tree (the tree of pci_bus and pci_dev structs) from the Open Firmware device tree rather than by probing PCI configuration space. The OF device tree has a node for each PCI device and bridge in the system, with properties that tell us what addresses the firmware has configured for them and other details. There are a couple of reasons why this is needed. First, on systems with a hypervisor, there is a PCI-PCI bridge per slot under the PCI host bridges. These PCI-PCI bridges have special isolation features for virtualization. We can't write to their config space, and we are not supposed to be reading their config space either. The firmware tells us about the address ranges that they pass in the OF device tree. Secondly, on powermacs, the interrupt controller is in a PCI device that may be behind a PCI-PCI bridge. If we happened to take an interrupt just at the point when the device or a bridge on the path to it was disabled for probing, we would crash when we try to access the interrupt controller. I have implemented a platform-specific function which is called for each PCI bridge (host or PCI-PCI) to say whether the code should look in the device tree or use normal PCI probing for the devices under that bridge. On pSeries machines we use the device tree if we're running under a hypervisor, otherwise we use normal probing. On powermacs we use normal probing for the AGP bridge, since the device for the AGP bridge itself isn't shown in the device tree (at least on my G5), and the device tree for everything else. This has been tested on a dual G5 powermac, a partition on a POWER5 machine (running under the hypervisor), and a legacy iSeries partition. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-09-10[PATCH] spinlock consolidationIngo Molnar
This patch (written by me and also containing many suggestions of Arjan van de Ven) does a major cleanup of the spinlock code. It does the following things: - consolidates and enhances the spinlock/rwlock debugging code - simplifies the asm/spinlock.h files - encapsulates the raw spinlock type and moves generic spinlock features (such as ->break_lock) into the generic code. - cleans up the spinlock code hierarchy to get rid of the spaghetti. Most notably there's now only a single variant of the debugging code, located in lib/spinlock_debug.c. (previously we had one SMP debugging variant per architecture, plus a separate generic one for UP builds) Also, i've enhanced the rwlock debugging facility, it will now track write-owners. There is new spinlock-owner/CPU-tracking on SMP builds too. All locks have lockup detection now, which will work for both soft and hard spin/rwlock lockups. The arch-level include files now only contain the minimally necessary subset of the spinlock code - all the rest that can be generalized now lives in the generic headers: include/asm-i386/spinlock_types.h | 16 include/asm-x86_64/spinlock_types.h | 16 I have also split up the various spinlock variants into separate files, making it easier to see which does what. The new layout is: SMP | UP ----------------------------|----------------------------------- asm/spinlock_types_smp.h | linux/spinlock_types_up.h linux/spinlock_types.h | linux/spinlock_types.h asm/spinlock_smp.h | linux/spinlock_up.h linux/spinlock_api_smp.h | linux/spinlock_api_up.h linux/spinlock.h | linux/spinlock.h /* * here's the role of the various spinlock/rwlock related include files: * * on SMP builds: * * asm/spinlock_types.h: contains the raw_spinlock_t/raw_rwlock_t and the * initializers * * linux/spinlock_types.h: * defines the generic type and initializers * * asm/spinlock.h: contains the __raw_spin_*()/etc. lowlevel * implementations, mostly inline assembly code * * (also included on UP-debug builds:) * * linux/spinlock_api_smp.h: * contains the prototypes for the _spin_*() APIs. * * linux/spinlock.h: builds the final spin_*() APIs. * * on UP builds: * * linux/spinlock_type_up.h: * contains the generic, simplified UP spinlock type. * (which is an empty structure on non-debug builds) * * linux/spinlock_types.h: * defines the generic type and initializers * * linux/spinlock_up.h: * contains the __raw_spin_*()/etc. version of UP * builds.

I did not try to build non-SMP kernels. That should be trivial to fix up later if necessary. I converted bit ops atomic_hash lock to raw_spinlock_t. Doing so avoids some ugly nesting of linux/*.h and asm/*.h files. Those particular locks are well tested and contained entirely inside arch specific code. I do NOT expect any new issues to arise with them. If someone does ever need to use debug/metrics with them, then they will need to unravel this hairball between spinlocks, atomic ops, and bit ops that exist only because parisc has exactly one atomic instruction: LDCW (load and clear word).

2005-09-09[PATCH] PPC64: large INITRD causes kernel not to bootMark Bellon
In PPC64 there are number of problems in arch/ppc64/boot/main.c that prevent a kernel from making use of a large (greater than ~16MB) INITRD. This is 64 bit architecture and really large INITRD images should be possible. Simply put the existing code has a fixed reservation (claim) address and once the kernel plus initrd image are large enough to pass this address all sorts of bad things occur. The fix is the dynamically establish the first claim address above the loaded kernel plus initrd (plus some "padding" and rounding). If PROG_START is defined this will be used as the minimum safe address - currently known to be 0x01400000 for the firmwares tested so far.
