* [POWERPC] PS3: Use the HVs storage device notification mechanism properlyGeert Uytterhoeven2008-01-253-234/+223
| | | | | | | | | | | | | | | | | | | The PS3 hypervisor has a storage device notification mechanism to wait until a storage device is ready. Unfortunately the storage device probing code used this mechanism in an incorrect way, needing a polling loop and handling of devices that are not yet ready. This change corrects this by: - First waiting for the reception of an asynchronous notification that a new storage device became ready, - Then looking up the storage device in the device repository. On shutdown, the storage probe thread is stopped and the storage notification device is closed using a reboot notifier.

| * [POWERPC] Make PS3_SYS_MANAGER default y, not mMichael Ellerman2007-12-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it's impossible to build a ps3_defconfig which will reboot without modules installed. This makes it all too easy to find yourself with a PS3 that won't reboot. This is because the system manager driver, which provides the reboot mechanism, is only selectable if PS3_ADVANCED is set, else it defaults to m. In ps3_defconfig PS3_ADVANCED is not set, therefore the system manager is built as a module. It would be desirable IMHO for the defconfig to produce a kernel that boots and reboots, without needing modules to be installed.

* | [POWERPC] cell: wrap master run control bitMasato Noguchi2007-12-211-2/+25
|/ | | | | | | | | | | | | | | | | | | | | | | | | Add platform specific SPU run control routines to the spufs. The current spufs implementation uses the SPU master run control bit (MFC_SR1[S]) to control SPE execution, but the PS3 hypervisor does not support the use of this feature. This change adds the run control wrapper routies spu_enable_spu() and spu_disable_spu(). The bare metal routines use the master run control bit, and the PS3 specific routines use the priv2 run control register. An outstanding enhancement for the PS3 would be to add a guard to check for incorrect access to the spu problem state when the spu context is disabled. This check could be implemented with a flag added to the spu context that would inhibit mapping problem state pages, and a routine to unmap spu problem state pages. When the spu is enabled with ps3_enable_spu() the flag would be set allowing pages to be mapped, and when the spu is disabled with ps3_disable_spu() the flag would be cleared and mapped problem state pages would be unmapped.

It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places.

* [POWERPC] Use 1TB segmentsPaul Mackerras2007-10-121-6/+8
| | | | | | | | | | | | | | | | | | | | This makes the kernel use 1TB segments for all kernel mappings and for user addresses of 1TB and above, on machines which support them (currently POWER5+, POWER6 and PA6T). We detect that the machine supports 1TB segments by looking at the ibm,processor-segment-sizes property in the device tree. We don't currently use 1TB segments for user addresses < 1T, since that would effectively prevent 32-bit processes from using huge pages unless we also had a way to revert to using 256MB segments. That would be possible but would involve extra complications (such as keeping track of which segment size was used when HPTEs were inserted) and is not addressed here. Parts of this patch were originally written by Ben Herrenschmidt. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | Currently if you don't specify a match callback for your irq_host it's assumed you match everything. This is a kind of opt-out approach, and turns out to be the exception rather than the rule. So change the semantics to be opt-in, ie. you don't match anything unless you provide a match callback. This in itself isn't very useful, but will allow us to provide a default match implementation in a subsequent patch.

| | | | | | | | | | | | | | | | On PS3, A storage device may show up in the repository before the hypervisor has finished probing: - If its type is not yet known, it shows up as PS3_DEV_TYPE_STOR_DUMMY, - If its regions are being probed, it shows up as having zero regions. If any of these happen, consider the device not yet present. The storage probe thread will retry later.

Although we don't have the facility to disable a SPE with supervisor-level privileges, it's better than hitting the BUG_ON unconditionally.

* [POWERPC] PS3: Bootwrapper support.Geoff Levand2007-07-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Add support to build the PS3 flash rom image and remove some unneeded lmb calls. The PS3's lv1 loader supports loading gzipped binary images from flash rom to addr zero. The loader enters the image at addr 0x100. In this implementation a bootwrapper overlay is use to arrange for the kernel to be loaded to addr zero and to have a suitable bootwrapper entry at 0x100. To construct the rom image, 0x100 bytes from offset 0x100 in the kernel is copied to the bootwrapper symbol __system_reset_kernel. The 0x100 bytes at the bootwrapper symbol __system_reset_overlay is then copied to offset 0x100. At runtime the bootwrapper program copies the 0x100 bytes at __system_reset_kernel to addr 0x100. zImage.ps3 is a wrapped image that contains a flat device tree, an lv1 compatible entry point, and an optional initrd. otheros.bld is the gzip compresed rom image built from zImage.ps3. otheros.bld is suitable for programming into the PS3 boot flash memory.
