| | | | | | | | | | | | | | While doing the C99 conversion I notices that the top level sh64 directory was using the binary number for CTL_KERN. That is a no-no so I removed the support for the sysctl binary interface only leaving sysctl /proc support.

| | | | | | | | | | | | | | | While C99 converting the ctl_table initializers I realized that the binary sysctl numbers were in conflict with the binary values under CTL_KERN. Including CTL_KERN KERN_VERSION as used by glibc. So I just removed the sysctl binary interface for these values, as it was unsupportable. Luckily these sysctl were inserted at the end of the sysctl list so this bug was not visible to userspace. Signed-off-by: Eric W.

| | | | | | | | | | | | | | This convters the sysctl ctl_tables to use C99 initializers. While I was looking at it I discovered it was using a portion of the sysctl binary addresses space under CTL_KERN KERN_OSTYPE which was completely inappropriate.

* [PATCH] sysctl: sn: remove sysctl ABI BREAKAGEEric W. Biederman2007-02-14
| | | | | | | | | | | | | | | | | | | By not using the enumeration in sysctl.h (or even understanding it) the SN platform placed their arch specific xpc directory on top of CTL_KERN and only because they didn't have 4 entries in their xpc directory got lucky and didn't break glibc. This is totally irresponsible. So this patch entirely removes sys_sysctl support from their sysctl code. Hopefully they don't have ascii name conflicts as well. And now that they have no ABI numbers add them to the end instead of the sysctl list instead of the head so nothing else will be overridden. Cc: Tony Luck <tony.luck@intel.com> Signed-off-by: Eric W.

| * [POWERPC] Use udbg_early_init() on ppc32David Gibson2007-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | udbg_early_init() is a function used on 64 bit systems, which initializes whichever early udbg backend is configured. This function is not called on 32-bit, however if btext early debug is enabled it does have an explicit, inline, #ifdef-ed assignment performing analagous initialization. This patch makes things more uniform by folding the btext initialization as an option into udbg_early_init() and calling that from the 32-bit setup path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This can be used for serial ports that are connected to an OF platform bus but are not autodetected by the lecacy serial support. It will automatically take over devices that come from the legacy serial detection, which usually is only one device. In some cases, rtas may be set up to use the serial port in the firmware, which allows easier debugging before probing the serial ports. In this case, the "used-by-rtas" property must be set by the firmware. This patch also adds code to the legacy serial driver to check for this.

Basically we fire up a time for every scheduler tick that searches for a higher or same priority thread that is on the runqueue and if there is one context switches to it. Because we can't lock spus from timer context we actually run this from a delayed runqueue instead of a timer. A nice optimization would be to skip the actual priority bitmap search when there are less contexts than physical spus available. To implement this I need a so far unpublished patch from Andre, and it will be added after we have that patch in. Note that right now we only do the time slicing for SCHED_RR tasks. The code would work for SCHED_OTHER tasks aswell, but their prio value is defered from the one the PPU thread has at time of spu_run, and using this for spu scheduling decisions would make the code very unfair. SCHED_OTHER support will be enabled once we the spu scheduler knows how to calculcate cpu_context.prio (very soon) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | unbind_context already sets the context state to SPU_STATE_SAVED, thus the spu_deactivate callers don't need to do it again. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
