2007-10-12Driver core: change add_uevent_var to use a structKay Sievers1-7/+2
This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

2007-10-12[POWERPC] Use 1TB segmentsPaul Mackerras1-6/+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>
2007-10-09[POWERPC] PS3: Add os-area database routinesGeoff Levand1-14/+431
Add support for a simple tagged database in the PS3 flash rom os-area. The database allows the flash rom os-area to be shared between a bootloader and installed operating systems. The application ps3-flash-util or the library libps3-utils from the ps3-utils package can be used for userspace database operations.

2007-09-14[POWERPC] Invert null match behaviour for irq_hostsMichael Ellerman1-0/+7
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.

2007-09-11[POWERPC] cell/PS3: Ignore storage devices that are still being probedGeert Uytterhoeven2-0/+30
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. This fixes the timing-dependent problem where a kernel booted from FLASH ROM sometimes cannot find the hard disk.

At present, running any SPE program on the ps3 will trigger a BUG_ON when spufs_run_spu tries to clear the master run control bit, as lv1 does not make the master run control available to Linux. This change makes SPE apps work again by disabling changes to the master run control on PS3. Although we don't have the facility to disable a SPE with supervisor-level privileges, it's better than hitting the BUG_ON unconditionally.

2007-07-10[POWERPC] PS3: Bootwrapper support.Geoff Levand1-2/+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.
