| * [PATCH] powerpc: properly configure DDR/P5IOC children devsJohn Rose2006-03-161-0/+28
| | | | | | | | | | | | | | | | | | | | | | The dynamic add path for PCI Host Bridges can fail to configure children adapters under P5IOC controllers. It fails to properly fixup bus/device resources, and it fails to properly enable EEH. Both of these steps need to occur before any children devices are enabled in pci_bus_add_devices().

| * [PATCH] powerpc: enable NAP only on cpus who support it to avoid memory ↵Benjamin Herrenschmidt2006-03-162-9/+4
| | | | | | | | | | | | | | | | | | | | | | corruption This patch fixes incorrect setting of powersave_nap to 1 on all PowerMacs, potentially causing memory corruption on some models.

| * powerpc: Disallow lparcfg being a modulePaul Mackerras2006-03-141-1/+1
| | | | | | | | | | | | | | | | | | | | The lparcfg code needs several things which are pretty arcane internal details and which we don't want to export, which means that lparcfg doesn't work when built as a module. This makes it a bool instead of a tristate in the Kconfig so that users can't try to build it as a module. Signed-off-by: Paul Mackerras <paulus@samba.org>

| * powerpc32: Fix timebase synchronization on 32-bit powermacsPaul Mackerras2006-03-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | The variable `timebase' used to transfer the current timebase value from one cpu to the other in smp_core99_give/take_timebase was only an unsigned long, i.e. 32 bits on 32-bit machines. It needs to be 64 bits. This makes it a u64, and fixes the issue reported by Kyle Moffett, that the two cpus see wildly different values for the time of day.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some hotplug driver functions were migrated to the kernel for use by EEH in commit 2bf6a8fa21570f37fd1789610da30f70a05ac5e3. Previously, the PCI Hotplug module had been changed to use the new OFDT-based PCI probe when appropriate: 5fa80fcdca9d20d30c9ecec30d4dbff4ed93a5c6 When rpaphp_pci_config_slot() was moved from the rpaphp driver to the new kernel function pcibios_add_pci_devices(), the OFDT-based probe stuff was dropped.

My original runlatch code would set it on every exception entry even though most of the time this was not required. It would also continually set it in the idle loop, which is an issue on an SMT capable processor. Now we cache the runlatch value in a threadinfo bit, and only check for it in decrementer and hardware interrupt exceptions as well as the idle loop.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | Some recent PowerBook models tend to lose the ethernet PHY on suspend/resume. It -seems- that they use a combo ethernet-firewire PHY chip and the firewire PHY seems to die the same way when that happens. Not trying to toggle the firewire cable power appears to fix it. So this patch disables changes to the firewire cable power control GPIO on those models.

| | | | | | | | | | | | | | | | | | | | Revert: 40727198bfb2ce5842a6e8c7f89cf8a40ff7bf14 These PHY changes hang the sungem driver on startup with Sun chips on sparc64.

| * [SUNGEM]: Make PM of PHYs more reliable (#2)Benjamin Herrenschmidt2006-01-241-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On my latest laptop, I've had occasional PHY dead on wakeup from sleep... the PHY would be totally unresponsive even to toggling the hard reset line until the machine is powered down... Looking closely at the code, I found some possible issues in the way we setup the MDIO lines during suspend along with slight divergences from what Darwin does when resetting it that may explain the problem. That patch change these and the problem appear to be gone for me at least... I also fixed an mdelay -> msleep while I was at it to the pmac feature code that is called when toggling the PHY reset line since sungem doesn't call it in an atomic context anymore.

* [PATCH] powerpc: Remove lppaca structure from the PACADavid Gibson2006-01-136-23/+20
| | | | | | | | | | | | | | | | | | At present the lppaca - the structure shared with the iSeries hypervisor and phyp - is contained within the PACA, our own low-level per-cpu structure. This doesn't have to be so, the patch below removes it, making a separate array of lppaca structures. This saves approximately 500*NR_CPUS bytes of image size and kernel memory, because we don't need aligning gap between the Linux and hypervisor portions of every PACA. On the other hand it means an extra level of dereference in many accesses to the lppaca. The patch also gets rid of several places where we assign the paca address to a local variable for no particular reason.
