| * | [PATCH] ppc32: add 440GX erratum 440_43 workaroundEugene Surovegin2006-04-28
| |/ | | | | | | | | | | | | | | | | | | This patch adds workaround for PPC 440GX erratum 440_43. According to this erratum spurious MachineChecks (caused by L1 cache parity) can happen during DataTLB miss processing. We disable L1 cache parity checking for 440GX rev.C and rev.F Signed-off-by: Eugene Surovegin <ebs@ebshome.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

* | [PATCH] powerpc: Kill _machine and hard-coded platform numbersBenjamin Herrenschmidt2006-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

* | ppc: Remove CHRP, POWER3 and POWER4 support from arch/ppcPaul Mackerras2006-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 32-bit CHRP machines are now supported only in arch/powerpc, as are all 64-bit PowerPC processors. This means that we don't use Open Firmware on any platform in arch/ppc any more. This makes PReP support a single-platform option like every other platform support option in arch/ppc now, thus CONFIG_PPC_MULTIPLATFORM is gone from arch/ppc. CONFIG_PPC_PREP is the option that selects PReP support and is generally what has replaced CONFIG_PPC_MULTIPLATFORM within arch/ppc. _machine is all but dead now, being #defined to 0. Updated Makefiles, comments and Kconfig options generally to reflect these changes. Signed-off-by: Paul Mackerras <paulus@samba.org>
* | powerpc: Unify the 32 and 64 bit idle loopsPaul Mackerras2006-03-26
| | | | | | | | | | | | | | | | | | | | This unifies the 32-bit (ARCH=ppc and ARCH=powerpc) and 64-bit idle loops. It brings over the concept of having a ppc_md.power_save function from 32-bit to ARCH=powerpc, which lets us get rid of native_idle(). With this we will also be able to simplify the idle handling for pSeries and cell. Signed-off-by: Paul Mackerras <paulus@samba.org>

* powerpc: Implement accurate task and CPU time accountingPaul Mackerras2006-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements accurate task and cpu time accounting for 64-bit powerpc kernels. Instead of accounting a whole jiffy of time to a task on a timer interrupt because that task happened to be running at the time, we now account time in units of timebase ticks according to the actual time spent by the task in user mode and kernel mode. We also count the time spent processing hardware and software interrupts accurately. This is conditional on CONFIG_VIRT_CPU_ACCOUNTING. If that is not set, we do tick-based approximate accounting as before. To get this accurate information, we read either the PURR (processor utilization of resources register) on POWER5 machines, or the timebase on other machines on * each entry to the kernel from usermode * each exit to usermode * transitions between process context, hard irq context and soft irq context in kernel mode * context switches. On POWER5 systems with shared-processor logical partitioning we also read both the PURR and the timebase at each timer interrupt and context switch in order to determine how much time has been taken by the hypervisor to run other partitions ("steal" time). Unfortunately, since we need values of the PURR on both threads at the same time to accurately calculate the steal time, and since we can only calculate steal time on a per-core basis, the apportioning of the steal time between idle time (time which we ceded to the hypervisor in the idle loop) and actual stolen time is somewhat approximate at the moment. This is all based quite heavily on what s390 does, and it uses the generic interfaces that were added by the s390 developers, i.e. account_system_time(), account_user_time(), etc. This patch doesn't add any new interfaces between the kernel and userspace, and doesn't change the units in which time is reported to userspace by things such as /proc/stat, /proc/<pid>/stat, getrusage(), times(), etc. Internally the various task and cpu times are stored in timebase units, but they are converted to USER_HZ units (1/100th of a second) when reported to userspace. Some precision is therefore lost but there should not be any accumulating error, since the internal accumulation is at full precision. Signed-off-by: Paul Mackerras <paulus@samba.org>

The default behaviour when nothing is disabled/enabled will be "all devices are enabled", which is the same as before. Also helper platform_notify_map function added, making assignment of board-specific platform_info more consistent and generic.

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: 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] powerpc: Merge cacheflush.h and cache.hDavid Gibson2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ppc32 and ppc64 versions of cacheflush.h were almost identical. The two versions of cache.h are fairly similar, except for a bunch of register definitions in the ppc32 version which probably belong better elsewhere. This patch, therefore, merges both headers. Notable points: - there are several functions in cacheflush.h which exist only on ppc32 or only on ppc64. These are handled by #ifdef for now, but these should probably be consolidated, along with the actual code behind them later. - Confusingly, both ppc32 and ppc64 have a flush_dcache_range(), but they're subtly different: it uses dcbf on ppc32 and dcbst on ppc64, ppc64 has a flush_inval_dcache_range() which uses dcbf. These too should be merged and consolidated later. - Also flush_dcache_range() was defined in cacheflush.h on ppc64, and in cache.h on ppc32. In the merged version it's in cacheflush.h - On ppc32 flush_icache_range() is a normal function from misc.S. On ppc64, it was wrapper, testing a feature bit before calling __flush_icache_range() which does the actual flush. This patch takes the ppc64 approach, which amounts to no change on ppc32, since CPU_FTR_COHERENT_ICACHE will never be set there, but does mean renaming flush_icache_range() to __flush_icache_range() in arch/ppc/kernel/misc.S and arch/powerpc/kernel/misc_32.S - The PReP register info from asm-ppc/cache.h has moved to arch/ppc/platforms/prep_setup.c - The 8xx register info from asm-ppc/cache.h has moved to a new asm-powerpc/reg_8xx.h, included from reg.h - flush_dcache_all() was defined on ppc32 (only), but was never called (although it was exported). Thus this patch removes it from cacheflush.h and from ARCH=powerpc (misc_32.S) entirely. It's left in ARCH=ppc for now, with the prototype moved to ppc_ksyms.c.

* [PATCH] powerpc: Merge signal.hDavid Gibson2005-11-09
| | | | | | | | | | | | | | | | | | | Having already merged the ppc and ppc64 versions of signal.c, this patch finishes the job by merging signal.h. The two versions were almost identical already. Notable changes: - We use BITS_PER_LONG to correctly size sigset_t - Remove some uneeded #includes and struct forward declarations. This does mean adding an include to signal_32.c which relied on the indirect inclusion of sigcontext.h - As the ppc64 version, the merged signal.h has prototypes for do_signal() and do_signal32(). Thus remove extra prototypes from ppc_ksyms.c which had them directly. Built and booted on POWER5 LPAR (ARCH=ppc64 and ARCH=powerpc). Built for 32-bit powermac (ARCH=ppc and ARCH=powerpc) and Walnut (ARCH=ppc). Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] ppc32: Update MPC834x platform to work with new phylibKumar Gala2005-11-09
| | | | | | | | | | | MPC834x uses the gianfar network driver which now uses the new phylib. We need to update the platform code to create a gianfar platform MDIO bus and pass the right intializations to the gianfar driver to make things work again.
