* [CELL] spufs: add spu stats in sysfs and ctx stat file in spufsAndre Detsch2007-07-207-73/+89
| | | | | | | | | | | | | | | | | | | | This patch exports per-context statistics in spufs as long as spu statistics in sysfs. It was formed by merging: "spufs: add spu stats in sysfs" From: Christoph Hellwig "spufs: add stat file to spufs" From: Christoph Hellwig "spufs: fix libassist accounting" From: Jeremy Kerr "spusched: fix spu utilization statistics" From: Luke Browning And some adjustments by myself, after suggestions on cbe-oss-dev. Having separate patches was making the review process harder than it should, as we end up integrating spus and ctx statistics accounting much more than it was on the first implementation.

* [CELL] spufs: Remove spurious WARN_ON for spu_deactivate for NOSCHED contextsJeremy Kerr2007-07-201-9/+0
| | | | | | | | | | | | | In 6cbf93960e64f313f6e247cbca7afaa50e3ee2c we added a WARN_ON for calling spu_deactivate on contexts created with the SPU_CREATE_NOSCHED flag. However, all NOSCHED contexts will need to be deactivated when the context is destroyed, so this gives a spurious warning when any NOSCHED context is closed. This change removes the WARN_ON.

* [CELL] spufs: Avoid unexpectedly restaring MFC during context saveKazunori Asayama2007-07-201-1/+2
| | | | | | | | | | | The current SPU context saving procedure in SPUFS unexpectedly restarts MFC when halting decrementer, because MFC_CNTL[Dh] is set without MFC_CNTL[Sm]. This bug causes, for example, saving broken DMA queues. Here is a patch to fix the problem.

* [CELL] add support for MSI on Axon-based Cell systemsMichael Ellerman2007-07-202-0/+447
| | | | | | | | | | | | | | This patch adds support for the setup and decoding of MSIs on Axon-based Cell systems, using the MSIC mechanism. This involves setting up an area of BE memory which the Axon then uses as a FIFO for MSI messages. When one or more MSIs are decoded by the MSIC we receive an interrupt on the MPIC, and the MSI messages are written into the FIFO. At the moment we use a 64KB FIFO, one per MSIC/BE.

* [CELL] driver for DDR2 memory on AXONMaxim Shchetynin2007-07-203-0/+392
| | | | | | | | | | | | | | | | | | The Axon bridge chip used on new Cell/B.E. based blade servers comes with a DDR2 memory controller that can be used to attach cheap memory modules, as opposed to the high-speed XDR memory that is used by the CPU itself. Since the memory controller does not participate in the cache coherency protocol, we can not use the memory direcly for Linux applications, but by providing a block device it can be used for swap space, temporary file storage and through the use of the direct_access block device operation for mapping into user addresses, when it is mounted with an appropriate file system.

* [CELL] allow linux to map Cell regs on legacy SLOF tree.Jean-Christophe DUBOIS2007-07-201-0/+7
| | | | | | | | | | | | | | The platforms missing the "cpus" property in the "be" node are mono-Cell platforms such as CAB or Getaway. Therefore it is possible to assume that if there is no "cpus" properties under the "be" node then we can safely return the "device node" without more checking. This is a bit hacky but ... it allows it to work on these platforms.

* [CELL] cbe_cpufreq: reorganize codeChristian Krafft2007-07-206-188/+309
| | | | | | | | | | | | This patch reorganizes the code of the driver into three files. Two cbe_cpufreq_pmi.c and cbe_cpufreq_pervasive.c care about hardware. cbe_cpufreq.c contains the logic. There is no changed behaviour, except that the PMI related function is now located in a seperate module cbe_cpufreq_pmi.

| | | | | | | | | | | | | | This patch fixes the initialization of the cbe_cpufreq driver. The code that initializes the PMI related functions was called per cpu: * registering cpufreq notifier block * registering a pmi handler This ends in a bug that the notifier block gets called in an endless loop. The initialization code is being put to the module init code path by this patch. This way it only gets called once.

* [CELL] pmi: remove support for mutiple devices.Christian Krafft2007-07-202-51/+36
| | | | | | | | | | | | | | | | | The pmi driver got simplified by removing support for multiple devices. As there is no more than one pmi device per maschine, there is no need to specify the device for listening and sending messages. This way the caller (cbe_cpufreq) doesn't need to scan the device tree. When registering the handler on a board without a pmi interface, pmi.c will just return -ENODEV. The patch that fixed the breakage of cell_defconfig has been broken out of the earlier version of this patch. So this is the version that applies cleanly on top of it.

The three main advantages with this controller over the existing ones are: - Both priority (ipr) and bitmap (intc2) registers are supported - External pin sense configuration is supported, ie edge vs level triggered - CPU/Board specific code maps 1:1 with datasheet for easy verification This controller can easily coexist with the current IPR and INTC2 controllers, but the idea is that CPUs/Boards should be moved over to this controller over time so we have a single code base to maintain.
