Likely" Date: Thu, 19 Jan 2006 01:12:48 -0700 Subject: [PATCH] powerpc: Migrate Xilinx Vertex support from the OCP bus to the platfom bus. This patch only deals with the serial port definitions as there is no support for any other xilinx IP cores in the kernel tree at the moment. Board specific configuration moved out of virtex.[ch] and into the xparameters.h wrapper. This also prepares for the transition to the flattened device tree model. When the bootloader provides a device tree generated from an xparameters.h files, the kernel will no longer need xparameters/*. The platform bus will get populated with data from the device tree, and the device drivers will be automatically connected to the devices. Only the bootloader (or ppcboot) will need xparameters directly. Signed-off-by: Grant C.

Sep 17 00:00:00 2001 From: Vitaly Bordug Date: Fri, 20 Jan 2006 22:22:36 +0300 Subject: [PATCH] ppc32: MPC885ADS, MPC866ADS and MPC8272ADS-specific platform stuff for fs_enet Added proper ppc_sys identification and fs_platform_info's for MPC 885ADS, 866ADS and 8272ADS, utilizing function assignment to remove/do not use platform devices which conflict with PD-incompatible drivers.

The few callers who do check just panic or BUG_ON. So make lmb_alloc() panic internally, to catch bugs at the source. The few callers who did check the result no longer need to. The only caller that did anything interesting with the return result was careful_allocation(). For it we create __lmb_alloc_base() which _doesn't_ panic automatically, a little messy, but passable.

Added ppc_sys_device_disable/enable function set, making it easier to disable all the inexistent/not utilized platform device way pdevs. By the check of the "disabled" bit in the config field of ppc_sys_specs, disabled platform devices will be either added/removed from the bus, or simply not registered on it, depending on the time when disable/enable call asserted. 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.

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//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.

This wastes 8K per node and complicates some cpu and memory hotplug situations, such as adding a resource that doesn't map to one of the nodes discovered at boot. Set nodes online as resources are scanned. Fall back to node 0 only when we're sure this isn't a NUMA machine. Instead of defaulting to node 0 for cases of hot-adding a resource which doesn't belong to any initialized node, assign it to the first online node.

Luckily before it passes paddr (calculated from paddr) to the hpte_insert routines it calls virt_to_abs() (aka. __pa()) on the address, so there isn't actually a bug. map_io_page() however does pass pstart properly, so currently it's broken AFAICT because we're calling __pa(paddr) which will get us something very large. Presumably no one's calling map_io_page() in the right context. Anyway, change htab_bolt_mapping() callers to properly pass pstart, and then use it properly in htab_bolt_mapping(), ie. don't call __pa() on it again. Booted on p5 LPAR, iSeries and Power3.
