If CONFIG_NUMA isn't set, we use the define in <linux/mmzone.h> for early_pfn_to_nid (which defines it to 0). Because of this, the prototype needs to move inside the CONFIG_NUMA too, or anal gcc's get really confused. Signed-off-by:

The recent cleanups to asm-i386/mmzone.h were suboptimal nesting an ifdef of the same symbol. This patch removes some of the ifdef'ery to make things more readable again. Signed-off-by:

There has been some discuss about solving the SMP MTRR suspend/resume breakage, but I didn't find a patch for it. This is an intent for it. The basic idea is moving mtrr initializing into cpu_identify for all APs (so it works for cpu hotplug). For BP, restore_processor_state is responsible for restoring MTRR. Signed-off-by:

We dont need to use the PERFMON exception on POWER5, in fact the firmware returns an error. Due to this just remove the warning. Also now that we have proper runlatch support we can remove the bootup hack. Signed-off-by:

Not sure if we really need this, but it was handy to know which iSeries loop I was testing. Be consistent about printing which idle loop we're using, with this patch we cover all cases. Signed-off-by:

Fix a compile warning introduced by the previous patches. Signed-off-by:

Anton Blanchard authored
- remove some unnecessary includes - add runlatch support - no need to use raw_smp_processor_id any more, current preempt debug logic checks for processes that are bound to one cpu. Signed-off-by:

- separate out sleep logic in dedicated_idle, it was so far indented that it got squashed against the right side of the screen. - add runlatch support, looping on runlatch disable. Signed-off-by:
-
Anton Blanchard authored
- remove min/max yield time, we dont use the values anywhere - separate shared and dedicated idle loops - check need_resched again with irqs off to avoid sleeping with pending work - continually set runlatch off in idle loop, this means we dont need to turn the runlatch off on exception exit and suffer that associated cost for all exceptions. (A future patch will turn the runlatch on at exception entry) Signed-off-by:

Now that the idle loop is configured by each platform we don't need idle_setup() anymore. Signed-off-by:

Michael Ellerman authored
This patch fixes up iSeries, pSeries, pmac and maple to set the correct idle function for each platform. Signed-off-by:

dedicated_idle() and shared_idle() are only used by pSeries, so move them into pSeries_setup.c Signed-off-by:

Move iSeries_idle() into iSeries_setup.c, no one else needs to know about it. Signed-off-by:

This patch adds an idle member to the ppc_md structure and calls it from cpu_idle(). If a platform leaves ppc_md.idle as null it will get the default idle loop default_idle(). Signed-off-by:

When registering the hvc console port, register a list of ops (read and write) to go with it, instead of calling fixed function names. This allows different ports to encode the data differently. Signed-off-by:

Milton Miller authored
Remove all the vio device driver code from hvc_console.c This will allow us to separate hvsi, hvc, and allow hvc_console to be used without the ppc64 vio layer. Signed-off-by:
-
Milton Miller authored
Separate the console setup routines of the hvc_console and the vio layer. Remove the call to find_init_vty from hvc_console.c. Fail the setup routine if the console doesn't exist, but register the console again when the specified channel is instantiated. This scheme maintains the print buffer semantics while eliminating callout and call back for the console code. Signed-off-by:

Check if a vterm was registered before accepting it as a console. Check that a slot hasn't been probed with a tty in hvc_instantiate(). Check that a slot hasn't been free'ed when handing out console device. Signed-off-by:

hvc_console checks MAGIC_SYSRQ and XMON config vars. Signed-off-by:

Milton Miller authored
Be thorough in our exit routine, since it says it is there to be so. Unregistering without registering is safe (checked in 2.6.10). Signed-off-by:

Guard the MAGIC_SYSRQ ^O to be just on the console channel. Make the other channels more transparent. Signed-off-by:

Have the hvc console code try to pull characters immediately when receiving an interrupt, and kick the poll thread only if the immediate poll indicates it needed a call back to do more work. Signed-off-by:
-
Milton Miller authored
Use the vterm numbers to match the vio devices being probed with the indices already allocated via the console initcall function hvc_find_vtys. The old code required hvc_find_vtys to "guess" the matching devices the vio subsystem would find and its probe order. Signed-off-by:

Milton Miller has done a lot of work to clean up our hvc_console code. One of the important things the following patch series does is separate the VIO layer from the hvc_console code. With the VIO specific code removed any ppc64 platform, or even any architecture, can use hvc_console as a generic polling console. You simply have to supply a get_chars and put_chars method and hvc_console does the rest of the work. You can even use it for an interrupt driven console. This patch: Rearrange the code in drivers/char/hvc_console.c to make future patches smaller. No actual code changes, just ordering of the functions in the file. Signed-off-by:

Enable the runlatch at the start of each exception. Unfortunately we are out of space in the 0x300 handler, so I added it a bit later. The SPR write is fairly expensive, perhaps we should cache the runlatch state in the paca and avoid the write when possible. We don't need to turn the runlatch off, we do that in the idle loop. Better to take the hit in the idle loop than for each exception exit. Signed-off-by:
