* [POWERPC] cell: abstract spu management routinesGeoff Levand2006-12-042-9/+36
| | | | | | | | | | | | | | | | | This adds a platform specific spu management abstraction and the coresponding routines to support the IBM Cell Blade. It also removes the hypervisor only resources that were included in struct spu. Three new platform specific routines are introduced, spu_enumerate_spus(), spu_create_spu() and spu_destroy_spu(). The underlying design uses a new type, struct spu_management_ops, to hold function pointers that the platform setup code is expected to initialize to instances appropriate to that platform. For the IBM Cell Blade support, I put the hypervisor only resources that were in struct spu into a platform specific data structure struct spu_pdata.

* [POWERPC] coredump: Add SPU elf notes to coredump.Dwayne Grant McConnell2006-12-043-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds SPU elf notes to the coredump. It creates a separate note for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1, /signal1_type, /signal2, /signal2_type, /event_mask, /event_status, /mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id. A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to specify they have extra elf core notes. A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the additional notes could be calculated and added to the notes phdr entry. A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes would be written after the existing notes. The SPU coredump code resides in spufs. Stub functions are provided in the kernel which are hooked into the spufs code which does the actual work via register_arch_coredump_calls(). A new set of __spufs_<file>_read/get() functions was provided to allow the coredump code to read from the spufs files without having to lock the SPU context for each file read from.

* [POWERPC] Distinguish POWER6 partition modes and tell userspacePaul Mackerras2006-12-041-2/+11
| | | | | | | | | | | | | | | | | This adds code to look at the properties firmware puts in the device tree to determine what compatibility mode the partition is in on POWER6 machines, and set the ELF aux vector AT_HWCAP and AT_PLATFORM entries appropriately. Specifically, we look at the cpu-version property in the cpu node(s). If that contains a "logical" PVR value (of the form 0x0f00000x), we call identify_cpu again with this PVR value. A value of 0x0f000001 indicates the partition is in POWER5+ compatibility mode, and a value of 0x0f000002 indicates "POWER6 architected" mode, with various extensions disabled. We also look for various other properties: ibm,dfp, ibm,purr and ibm,spurr. Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] cell: Add oprofile supportMaynard Johnson2006-12-043-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add PPU event-based and cycle-based profiling support to Oprofile for Cell. Oprofile is expected to collect data on all CPUs simultaneously. However, there is one set of performance counters per node. There are two hardware threads or virtual CPUs on each node. Hence, OProfile must multiplex in time the performance counter collection on the two virtual CPUs. The multiplexing of the performance counters is done by a virtual counter routine. Initially, the counters are configured to collect data on the even CPUs in the system, one CPU per node. In order to capture the PC for the virtual CPU when the performance counter interrupt occurs (the specified number of events between samples has occurred), the even processors are configured to handle the performance counter interrupts for their node. The virtual counter routine is called via a kernel timer after the virtual sample time. The routine stops the counters, saves the current counts, loads the last counts for the other virtual CPU on the node, sets interrupts to be handled by the other virtual CPU and restarts the counters, the virtual timer routine is scheduled to run again. The virtual sample time is kept relatively small to make sure sampling occurs on both CPUs on the node with a relatively small granularity. Whenever the counters overflow, the performance counter interrupt is called to collect the PC for the CPU where data is being collected. The oprofile driver relies on a firmware RTAS call to setup the debug bus to route the desired signals to the performance counter hardware to be counted. The RTAS call must set the routing registers appropriately in each of the islands to pass the signals down the debug bus as well as routing the signals from a particular island onto the bus. There is a second firmware RTAS call to reset the debug bus to the non pass thru state when the counters are not in use.

* [POWERPC] Allow hooking of PCI MMIO & PIO accessors on 64 bitsBenjamin Herrenschmidt2006-12-046-361/+477
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the way iSeries hooks on PCI IO operations (both MMIO and PIO) and provides a generic way for other platforms to do so (we have need to do that for various other platforms). While reworking the IO ops, I ended up doing some spring cleaning in io.h and eeh.h which I might want to split into 2 or 3 patches (among others, eeh.h had a lot of useless stuff in it). A side effect is that EEH for PIO should work now (it used to pass IO ports down to the eeh address check functions which is bogus). Also, new are MMIO "repeat" ops, which other archs like ARM already had, and that we have too now: readsb, readsw, readsl, writesb, writesw, writesl. In the long run, I might also make EEH use the hooks instead of wrapping at the toplevel, which would make things even cleaner and relegate EEH completely in platforms/iseries, but we have to measure the performance impact there (though it's really only on MMIO reads) Since I also need to hook on ioremap, I shuffled the functions a bit there. I introduced ioremap_flags() to use by drivers who want to pass explicit flags to ioremap (and it can be hooked). The old __ioremap() is still there as a low level and cannot be hooked, thus drivers who use it should migrate unless they know they want the low level version. The patch "arch provides generic iomap missing accessors" (should be number 4 in this series) is a pre-requisite to provide full iomap API support with this patch.

We use the new dev_archdata structure to add the dma operations pointer and associated data to struct device. While at it, we also add the OF node pointer and numa node. In the future, we might want to look into merging that with pci_dn as well. The old vio, pci-iommu and pci-direct DMA ops are gone. They are now replaced by a set of generic iommu and direct DMA ops (non PCI specific) that can be used by bus types. The toplevel implementation is now inline.

* [POWERPC] Souped-up of_platform_device supportBenjamin Herrenschmidt2006-12-042-32/+62
| | | | | | | | | | | | | | | | | | | | | | | | This patch first splits of_device.c and of_platform.c, the later containing the bits relative to of_platform_device's. On the "breaks" side of things, drivers uisng of_platform_device(s) need to include asm/of_platform.h now and of_(un)register_driver is now of_(un)register_platform_driver. In addition to a few utility functions to locate of_platform_device(s), the main new addition is of_platform_bus_probe() which allows the platform code to trigger an automatic creation of of_platform_devices for a whole tree of devices. The function acts based on the type of the various "parent" devices encountered from a provided root, using either a default known list of bus types that can be "probed" or a passed-in list. It will only register devices on busses matching that list, which mean that typically, it will not register PCI devices, as expected (since they will be picked up by the PCI layer). This will be used by Cell platforms using 4xx-type IOs in the Axon bridge and can be used by any embedded-type device as well.

* [POWERPC] Improve MPIC driver auto-configuration from DTBenjamin Herrenschmidt2006-12-041-2/+2
| | | | | | | | | | | | This patch applies on top of the MPIC DCR support. It makes the MPIC driver capable of a lot more auto-configuration based on the device-tree, for example, it can retreive it's own physical address if not passed as an argument, find out if it's DCR or MMIO mapped, and set the BIG_ENDIAN flag automatically in the presence of a "big-endian" property in the device-tree node.

Such implementations have the MPIC_USES_DCR flag set and don't use the phys_addr argument of mpic_alloc (they require a valid dcr mapping in the device node) This version of the patch can use a little bif of cleanup still (I can probably consolidate rb->dbase/doff, at least once I'm sure on how the hardware is actually supposed to work vs. possible simulator issues) and it should be possible to build a DCR-only version of the driver. I need to cleanup a bit the CONFIG_* handling for that and probably introduce CONFIG_MPIC_MMIO and CONFIG_MPIC_DCR.

It makes pci_read_irq_line() called by default in the PCI code for devices that are probed, and add an optional per-device fixup in ppc_md for platforms that really need to correct what they obtain from pci_read_irq_line(). It also removes ppc_md.irq_bus_setup which was only used by pSeries and should not be needed anymore. I've also removed the pSeries s7a workaround as it can't work with the current interrupt code anyway. I'm trying to get one of these machines working so I can test a proper fix for that problem. I also haven't updated the old-style fixup code from 85xx_cds.c because it's actually buggy :) It assigns pci_dev->irq hard coded numbers which is no good with the new IRQ mapping code. It should at least use irq_create_mapping(NULL, hard_coded_number); and possibly also set_irq_type() to set them as level low.

| | | | | | | | | | | | | | | | | | | | Adding the alignment to the size doesn't make any sense, what it should do is align the size of the conntrack structure to the alignment requirements of the helper structure and return an aligned pointer in nfct_help().

| | | | | | | | | | | | | | | | | | Accept -1 as delimiter to abort parsing without an error at the first unknown character. This is needed by the upcoming nf_conntrack SIP helper, where addresses are delimited by either '\r' or '\n' characters. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| * [NET_SCHED]: Fix endless loops caused by inaccurate qlen counters (part 1)Patrick McHardy2006-12-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are multiple problems related to qlen adjustment that can lead to an upper qdisc getting out of sync with the real number of packets queued, leading to endless dequeueing attempts by the upper layer code. All qdiscs must maintain an accurate q.qlen counter. There are basically two groups of operations affecting the qlen: operations that propagate down the tree (enqueue, dequeue, requeue, drop, reset) beginning at the root qdisc and operations only affecting a subtree or single qdisc (change, graft, delete class). Since qlen changes during operations from the second group don't propagate to ancestor qdiscs, their qlen values become desynchronized. This patch adds a function to propagate qlen changes up the qdisc tree, optionally calling a callback function to perform qdisc-internal maintenance when the child qdisc becomes empty. The follow-up patches will convert all qdiscs to use this function where necessary. Noticed by Timo Steinbach <tsteinbach@astaro.com>.

| * NetLabel: convert to an extensibile/sparse category bitmapPaul Moore2006-12-031-3/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original NetLabel category bitmap was a straight char bitmap which worked fine for the initial release as it only supported 240 bits due to limitations in the CIPSO restricted bitmap tag (tag type 0x01). This patch converts that straight char bitmap into an extensibile/sparse bitmap in order to lay the foundation for other CIPSO tag types and protocols. This patch also has a nice side effect in that all of the security attributes passed by NetLabel into the LSM are now in a format which is in the host's native byte/bit ordering which makes the LSM specific code much simpler; look at the changes in security/selinux/ss/ebitmap.c as an example.
