* [PATCH] PCI: Export pci_cfg_space_sizeBenjamin Herrenschmidt2006-01-091-0/+1
| | | | | | | | | | The powerpc PCI code sets up the PCI tree without doing config space accesses in most cases, from the firmware tree. However, it still wants to call pci_cfg_space_size() under some conditions, thus it needs to be made non-static (though I don't see a point to export it to modules).

| * [PATCH] 3/5 powerpc: Add platform functions interpreterBenjamin Herrenschmidt2006-01-093-0/+275
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the platform function interpreter itself along with the backends for UniN/U3/U4, mac-io, GPIOs and i2c. It adds the ability to execute those do-platform-* scripts in the device-tree (at least for most devices for which a backend is provided). This should replace the clock spreading hacks properly. It might also have an impact on all sort of machines since some of the scripts marked "at init" will now be executed on boot (or some other on sleep/wakeup), those will possibly do things that the kernel didn't do at all, like setting some values into some i2c devices (changing thermal sensor calibration or conversion rate) etc... Thus regression testing is MUCH welcome. Also loook for errors in dmesg. That's also why I've left rather verbose debugging enabled in this version of the patch. (I do expect some Windtunnel G4s to show some errors as they have an i2c clock chip on the PMU bus that uses some primitives that the i2c backend doesn't implement yet. I really need users that have one of those machine to come back to me so we can get that done right, though the errors themselves should be harmless, I suspect the machine might not run at full speed).

| * [PATCH] 2/5 powerpc: Rework PowerMac i2c part 2Benjamin Herrenschmidt2006-01-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the continuation of the previous patch. This one removes the old PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them both with a single stub driver that uses the new PowerMac low i2c layer. Now that i2c-keywest is gone, the low-i2c code is extended to support interrupt driver transfers. All i2c busses now appear as platform devices. Compatibility with existing drivers should be maintained as the i2c bus names have been kept identical, except for the SMU bus but in that later case, all users has been fixed. With that patch added, matching a device node to an i2c_adapter becomes trivial. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [PATCH] 1/5 powerpc: Rework PowerMac i2c part 1Benjamin Herrenschmidt2006-01-094-31/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first part of a rework of the PowerMac i2c code. It completely reworks the "low_i2c" layer. It is now more flexible, supports KeyWest, SMU and PMU i2c busses, and provides functions to match device nodes to i2c busses and adapters. This patch also extends & fix some bugs in the SMU driver related to i2c support and removes the clock spreading hacks from the pmac feature code rather than adapting them to the new API since they'll be replaced by the platform function code completely in patch 3/5 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | For far, all SPU triggered interrupts always end up on the first SMT thread, which is a bad solution. This patch implements setting the affinity to the CPU that was running last when entering execution on an SPU. This should result in a significant reduction in IPI calls and better cache locality for SPE thread specific data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a hypervisor based setup, direct access to the first priviledged register space can typically not be allowed to the kernel and has to be implemented through hypervisor calls. As suggested by Masato Noguchi, let's abstract the register access trough a number of function calls. Since there is currently no public specification of actual hypervisor calls to implement this, I only provide a place that makes it easier to hook into.

| * [PATCH] powerpc: Replace VMALLOCBASE with VMALLOC_STARTDavid Gibson2006-01-092-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ppc64, we independently define VMALLOCBASE and VMALLOC_START to be the same thing: the start of the vmalloc() area at 0xd000000000000000. VMALLOC_START is used much more widely, including in generic code, so this patch gets rid of the extraneous VMALLOCBASE. This does require moving the definitions of region IDs from page_64.h to pgtable.h, but they don't clearly belong in the former rather than the latter, anyway. While we're moving them, clean up the definitions of the REGION_IDs: - Abolish REGION_SIZE, it was only used once, to define REGION_MASK anyway - Define the specific region ids in terms of the REGION_ID() macro. - Define KERNEL_REGION_ID in terms of PAGE_OFFSET rather than KERNELBASE. It amounts to the same thing, but conceptually this is about the region of the linear mapping (which starts at PAGE_OFFSET) rather than of the kernel text itself (which is at KERNELBASE).

| * [PATCH] spufs: Improved SPU preemptability [part 2].Arnd Bergmann2006-01-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reduces lock complexity of SPU scheduler, particularly for involuntary preemptive switches. As a result the new code does a better job of mapping the highest priority tasks to SPUs. Lock complexity is reduced by using the system default workqueue to perform involuntary saves. In this way we avoid nasty lock ordering problems that the previous code had. A "minimum timeslice" for SPU contexts is also introduced. The intent here is to avoid thrashing. While the new scheduler does a better job at prioritization it still does nothing for fairness.

As part of this restructuring, the control logic for the "run" operation is moved from arch/ppc64/kernel/spu_base.c to fs/spufs/file.c. Of course the base retains "bottom half" handlers for class{0,1} irqs. The new run loop will re-acquire an SPU if preempted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a few places where we need to fix things up for the kernel to work if it's linked at 32MB: - platforms/powermac/smp.c To start secondary cpus on pmac we patch the reset vector, which is fine. Except if we're above 32MB we don't have enough bits for an absolute branch, it needs to relative. - kernel/head_64.s - A few branches in the cpu hold code need to load the full target address and do a bctr. - after_prom_start needs to load PHYSICAL_START as the dest address, not 0. - The exception prolog needs to load the low word of the target adddress, not just the low halfword. - Fixup handling of the initial stab address. - kernel/setup_64.c smp_release_cpus() needs to write 1 to the spinloop flag near 0, not 32 MB.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes several unnecessary fields from the paca: - next_jiffy_update_tb was simply unused. Remove trivially. - The exdsi exception save area was not used. There were plans to use it, but they never seem to have gone anywhere. If they ever do, we can put it back. Remove from the paca, and from asm-offsets.c - The default_decr field was used from asm, but was only ever assigned the value of tb_ticks_per_jiffy. Just access tb_ticks_per_jiffy from asm directly instead. Built and booted on POWER5 LPAR and iSeries RS64.

| * [PATCH] powerpc: Remove ItLpRegSave area from the pacaDavid Gibson2006-01-092-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On iSeries, the paca contains, amongst other things an ItLpRegSave structure used by the hypervisor to save registers. The hypervisor locates this area through a pointer at the beginning of the paca, so the structure itself can be located elsewhere. This patch moves the reg_save area out into its own array. This reduces the amount of iSeries specific gunk which is visible to general powerpc code via paca.h Built and booted on POWER5 LPAR and iSeries RS64.

| * [PATCH] powerpc: Add back support for booting from BootX (#2)Benjamin Herrenschmidt2006-01-091-0/+166
| | | | | | | | | | | | | | | | | | | | ARCH=powerpc couldn't boot from BootX as it uses a "different" way of getting in the kernel. This patch adds the necessary trampolines, creating a flattened device-tree from the tree passed from MacOS, and initializing the btext engine early for really-early debugging.

| * [PATCH] powerpc: Unify udbg (#2)Benjamin Herrenschmidt2006-01-094-14/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch unifies udbg for both ppc32 and ppc64 when building the merged achitecture. xmon now has a single "back end". The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.

| * [PATCH] powerpc: serial port discovery (#2)Benjamin Herrenschmidt2006-01-093-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the discovery of legacy serial ports to a separate file, makes it common to ppc32 and ppc64, and reworks it to use the new OF address translators to get to the ports early. This new version can also detect some PCI serial cards using legacy chips and will probably match those discovered port with the default console choice. Only ppc64 gets udbg still yet, unifying udbg isn't finished yet. It also adds some speed-probing code to udbg so that the default console can come up at the same speed it was set to by the firmware.

| * [PATCH] powerpc: Add OF address parsing code (#2)Benjamin Herrenschmidt2006-01-093-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parsing addresses extracted from Open Firmware isn't a simple matter. We have various bits of code that try to do it in various place, including some heuristics in prom.c that pre-parse addresses at boot and fill device-nodes "addrs", but those are dodgy at best and I want to deprecate them. So this patch introduces a new set of routines that should be capable of parsing most types of addresses and translating them into CPU physical addresses. It currently works for things on PCI busses and ISA busses and should work on "standard" busses like the root bus or the MacIO bus that don't put funky flags in addresses. If you have other bus types that do use funky flags, you'll have to add new bus type translators, which is fairly easy.
