| * powerpc: Use correct sequence for putting CPU into nap modePaul Mackerras2006-04-187-65/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We weren't using the recommended sequence for putting the CPU into nap mode. When I changed the idle loop, for some reason 7447A cpus started hanging when we put them into nap mode. Changing to the recommended sequence fixes that. The complexity here is that the recommended sequence is a loop that keeps putting the cpu back into nap mode. Clearly we need some way to break out of the loop when an interrupt (external interrupt, decrementer, performance monitor) occurs. Here we use a bit in the thread_info struct to indicate that we need this, and the exception entry code notices this and arranges for the exception to return to the value in the link register, thus breaking out of the loop. We use a new `local_flags' field in the thread_info which we can alter without needing to use an atomic update sequence. The PPC970 has the same recommended sequence, so we do the same thing there too. This also fixes a bug in the kernel stack overflow handling code on 32-bit, since it was causing a value that we needed in a register to get trashed. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We found that when the 'decrementer' is saved, the PPE saves the current time 'csa->suspend_time'. When restoring the 'decrementer', (Step 34) decrementer seems to be adjusted with the number of cycles th= at a spu thread has not been running. In that code it is missing a substract ('-') because 'delta_time' is assigned a not substracted(see bellow).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Compile the 32bit kernel with -mcpu=powerpc. This reduces the imagesize when a compiler is used that defaults to -mtune=power4. It inserts lots of nops to please the 64bit cpu instruction scheduling. But all these nops are not needed for 32bit kernels.

I have about 100 Linux boxes (all with the same (binary the same) kernel). Last time I have upgraded all those boxes from 2.4.32 to 2.6.15.6 (first 2.6.15.1, next .2, .4 and .6) and I have found some problems on VIA based PC's. Probably the reason of this is that some VIA chipsets are unrecognized by IRQ router. In line 586 there is: /* FIXME: add new ones for 8233/5 */ There were only a few of chipsets ID's there, some of my VIA chipsets were not present and kernel used default IRQ router. I have added three entries, so that the code looks like: case PCI_DEVICE_ID_VIA_82C596: case PCI_DEVICE_ID_VIA_82C686: case PCI_DEVICE_ID_VIA_8231: case PCI_DEVICE_ID_VIA_8233A: case PCI_DEVICE_ID_VIA_8235: case PCI_DEVICE_ID_VIA_8237: case PCI_DEVICE_ID_VIA_8237_SATA: /* FIXME: add new ones for 8233/5 */ r->name = "VIA"; r->get = pirq_via_get; r->set = pirq_via_set; return 1; } The kernel goes fine but I haven't testes it for weeks, I'm just a moment after reboot :) One thing is different (better?): Using previus kernel I had: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 0 now I have: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 11 Maybe it is good idea to add there some more VIA chipsets?

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64. Currently all three arches compile it from arch/i386, which means that ia64 and x86_64 depend on things in arch/i386 that they wouldn't otherwise care about. This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing trailing whitespace) and the associated Makefile changes. All three architectures already set CONFIG_DMI in their top-level Kconfig files.

| * | | [IA64] Failure to resume after INIT in user spaceKeith Owens2006-04-081-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OS INIT handler is loading incorrect values into cr.ifa on exit. This shows up as a hang when resuming after an INIT that is delivered while a cpu is in user space. Correct the value loaded into cr.ifa.

| * | | [IA64] Pass more data to the MCA/INIT notify_die hooksKeith Owens2006-04-081-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MCA/INIT handlers maintain important state in the SAL to OS (sos) area and in the monarch_cpu flag. Kernel debuggers (such as KDB) need this data, and may need to adjust the monarch_cpu field so make the data available to the notify_die hooks. Define two more events for calling the functions on the notify_die chain. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu under arch/ia64/kernel/.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of the manual search of _CRS, in favor of acpi_get_vendor_resource() which is now provided by the ACPI CA. And fall back to searching for a consumer-only address space descriptor if no vendor-defined resource is found.
