* [PATCH] powerpc: convert macio_asic to use prom_parseBenjamin Herrenschmidt2006-01-08

* [PATCH] powerpc: Add back support for booting from BootX (#2)Benjamin Herrenschmidt2006-01-08
| | | | | | | | | | 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 Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | | | 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 Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | 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 Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | | 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.

* [PATCH] spufs: cooperative scheduler supportArnd Bergmann2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | This adds a scheduler for SPUs to make it possible to use more logical SPUs than physical ones are present in the system. Currently, there is no support for preempting a running SPU thread, they have to leave the SPU by either triggering an event on the SPU that causes it to return to the owning thread or by sending a signal to it. This patch also adds operations that enable accessing an SPU in either runnable or saved state. We use an RW semaphore to protect the state of the SPU from changing underneath us, while we are holding it readable. In order to change the state, it is acquired writeable and a context save or restore is executed before downgrading the semaphore to read-only.

* [PATCH] spufs: switchable spu contextsMark Nutter2006-01-08
| | | | | | | | | | | | | | Add some infrastructure for saving and restoring the context of an SPE. This patch creates a new structure that can hold the whole state of a physical SPE in memory. It also contains code that avoids races during the context switch and the binary code that is loaded to the SPU in order to access its registers.

* [PATCH] spufs: The SPU file system, baseArnd Bergmann2006-01-08
| | | | | | | | | | | | | | | | | | | | | This is the current version of the spu file system, used for driving SPEs on the Cell Broadband Engine. This release is almost identical to the version for the 2.6.14 kernel posted earlier, which is available as part of the Cell BE Linux distribution from http://www.bsc.es/projects/deepcomputing/linuxoncell/. The first patch provides all the interfaces for running spu application, but does not have any support for debugging SPU tasks or for scheduling. Both these functionalities are added in the subsequent patches. See Documentation/filesystems/spufs.txt on how to use spufs.

* [PATCH] syscall entry/exit revampDavid Woodhouse2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cleanup patch speeds up the null syscall path on ppc64 by about 3%, and brings the ppc32 and ppc64 code slightly closer together. The ppc64 code was checking current_thread_info()->flags twice in the syscall exit path; once for TIF_SYSCALL_T_OR_A before disabling interrupts, and then again for TIF_SIGPENDING|TIF_NEED_RESCHED etc after disabling interrupts. Now we do the same as ppc32 -- check the flags only once in the fast path, and re-enable interrupts if necessary in the ptrace case. The patch abolishes the 'syscall_noerror' member of struct thread_info and replaces it with a TIF_NOERROR bit in the flags, which is handled in the slow path. This shortens the syscall entry code, which no longer needs to clear syscall_noerror. The patch adds a TIF_SAVE_NVGPRS flag which causes the syscall exit slow path to save the non-volatile GPRs into a signal frame. This removes the need for the assembly wrappers around sys_sigsuspend(), sys_rt_sigsuspend(), et al which existed solely to save those registers in advance. It also means I don't have to add new wrappers for ppoll() and pselect(), which is what I was supposed to be doing when I got distracted into this... Finally, it unifies the ppc64 and ppc32 methods of handling syscall exit directly into a signal handler (as required by sigsuspend et al) by introducing a TIF_RESTOREALL flag which causes _all_ the registers to be reloaded from the pt_regs by taking the ret_from_exception path, instead of the normal syscall exit path which stomps on the callee-saved GPRs. It appears to pass an LTP test run on ppc64, and passes basic testing on ppc32 too. Brief tests of ptrace functionality with strace and gdb also appear OK. I wouldn't send it to Linus for 2.6.15 just yet though :) Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [PATCH] powerpc: Merge kexecMichael Ellerman2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch merges, to some extent, the PPC32 and PPC64 kexec implementations. We adopt the PPC32 approach of having ppc_md callbacks for the kexec functions. The current PPC64 implementation becomes the "default" implementation for PPC64 which platforms can select if they need no special treatment. I've added these default callbacks to pseries/maple/cell/powermac, this means iSeries no longer supports kexec - but it never worked anyway. I've renamed PPC32's machine_kexec_simple to default_machine_kexec, inline with PPC64. Judging by the comments it might be better named machine_kexec_non_of, or something, but at the moment it's the only implementation for PPC32 so it's the "default". Kexec requires machine_shutdown(), which is in machine_kexec.c on PPC32, but we already have in setup-common.c on powerpc. All this does is call ppc_md.nvram_sync, which only powermac implements, so instead make machine_shutdown a ppc_md member and have it call core99_nvram_sync directly on powermac. I've also stuck relocate_kernel.S into misc_32.S for powerpc. Built for ARCH=ppc, and 32 & 64 bit ARCH=powerpc, with KEXEC=y/n. Booted on P5 LPAR and successfully kexec'ed.
