| * [POWERPC] 4xx: Enable EMAC on Bamboo boardJosh Boyer2007-10-193-50/+76
| | | | | | | | | | | | | | | | Fix some device tree omissions that prevented the new EMAC driver from setting up ethernet on the Bamboo board correctly and update the Bamboo defconfig. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
| * [POWERPC] 4xx: Enable EMAC for PPC405 Walnut boardJosh Boyer2007-10-194-43/+66
| | | | | | | | | | | | | | | | | | This patch enables the ibm_newemac driver for the Walnut board. It fixes the device tree for the walnut board to order the MAL interrupts correctly and adds the local-mac-address property to the EMAC node. The bootwrapper is also updated to extract the MAC address from the OpenBIOS offset where it is stored. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
| * [POWERPC] 4xx: Fix timebase clock selection on WalnutJosh Boyer2007-10-191-2/+2
| | | | | | | | | | | | | | | | The current bootwrapper fails to set the timebase clock to the CPU clock which causes the time to increment incorrectly. This fixes it by using the correct #define for the CPC0_CR1 register. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

| * [POWERPC] 4xx: Split early debug output and early boot console for 44xValentine Barshak2007-10-192-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently there's no way to enable early boot console on PowerPC 44x not specifying uart's physical address in kernel config, which is used for very early debug messages. This patch splits very early debug output (which needs uart physical address in kernel config) and early boot console (which searches for uarts in the device tree using find_legacy_serial_ports). We enable early boot console for all 44x processors, while (dangerous) early debug is user-selectable.

* | pid namespaces: define is_global_init() and is_container_init()Serge E. Hallyn2007-10-193-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is_init() is an ambiguous name for the pid==1 check. Split it into is_global_init() and is_container_init(). A cgroup init has it's tsk->pid == 1. A global init also has it's tsk->pid == 1 and it's active pid namespace is the init_pid_ns. But rather than check the active pid namespace, compare the task structure with 'init_pid_ns.child_reaper', which is initialized during boot to the /sbin/init process and never changes. Changelog: 2.6.22-rc4-mm2-pidns1: - Use 'init_pid_ns.child_reaper' to determine if a given task is the global init (/sbin/init) process. This would improve performance and remove dependence on the task_pid(). 2.6.21-mm2-pidns2: - [Sukadev Bhattiprolu] Changed is_container_init() calls in {powerpc, ppc,avr32}/traps.c for the _exception() call to is_global_init(). This way, we kill only the cgroup if the cgroup's init has a bug rather than force a kernel panic.

* powerpc: add scaled time accountingMichael Neuling2007-10-182-2/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds POWERPC specific hooks for scaled time accounting. POWER6 includes a SPURR register. The SPURR is based off the PURR register but is scaled based on CPU frequency and issue rates. This gives a more accurate account of the instructions used per task. The PURR and timebase will be constant relative to the wall clock, irrespective of the CPU frequency. This implementation reads the SPURR register in account_system_vtime which is only call called on context witch and hard and soft irq entry and exit. The percentage of user and system time is then estimated using the ratio of these accounted by the PURR. If the SPURR is not present, the PURR read. An earlier implementation of this patch read the SPURR whenever the PURR was read, which included the system call entry and exit path. Unfortunately this showed a performance regression on lmbench runs, so was re-implemented. I've included the lmbench results here when run bare metal on POWER6. 1st column is the unpatch results. 2nd column is the results using the below patch and the 3rd is the % diff of these results from the base. 4th and 5th columns are the results and % differnce from the base using the older patch (SPURR read in syscall entry/exit path).

* serial: turn serial console suspend a boot rather than compile time optionAndres Salomon2007-10-181-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, there's a CONFIG_DISABLE_CONSOLE_SUSPEND that allows one to stop the serial console from being suspended when the rest of the machine goes to sleep. This is incredibly useful for debugging power management-related things; however, having it as a compile-time option has proved to be incredibly inconvenient for us (OLPC). There are plenty of times that we want serial console to not suspend, but for the most part we'd like serial console to be suspended. This drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel boot parameter (no_console_suspend). By default, the serial console will be suspended along with the rest of the system; by passing 'no_console_suspend' to the kernel during boot, serial console will remain alive during suspend. For now, this is pretty serial console specific; further fixes could be applied to make this work for things like netconsole. Signed-off-by: Andres Salomon <dilinger@debian.org> Acked-by: "Rafael J.

| | | | | | | | | | | | | | | | The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend.  Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'.  In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly.

| | | | | | | | | | | | | | | | | | | | | | Move the definition of 'struct pm_ops' and related functions from <linux/pm.h> to <linux/suspend.h> . There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

| | * [POWERPC] bestcomm: core bestcomm support for Freescale MPC5200Sylvain Munaut2007-10-169-0/+1312
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the core of the BestComm API for the Freescale MPC5200(b). The BestComm engine is a microcode-controlled / tasks-based DMA used by several of the onchip devices. Setting up the tasks / memory allocation and all common low level functions are handled by this patch. The specifics details of each tasks and their microcode are split-out in separate patches. This is not the official API, but a much cleaner one. (hopefully) Signed-off-by: Sylvain Munaut <tnt@246tNt.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

This fixes it. Problem identified by Andrew Haley, and fix provided by Jakub Jelinek (thanks !). Unfortunately, a bug in gcc cause it to not quite work either, but that is being fixed separately with something around the lines of: linux-unwind.h: fs->regs.reg[R_CR2].loc.offset = (long) &regs->ccr - new_cfa; + /* CR? regs are just 32-bit and PPC is big-endian. */ + fs->regs.reg[R_CR2].loc.offset += sizeof (long) - 4; (According to Jakub) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * | [POWERPC] Add 1TB workaround for PA6TOlof Johansson2007-10-173-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PA6T has a bug where the slbie instruction does not honor the large segment bit. As a result, we have to always use slbia when switching context. We don't have to worry about changing the slbie's during fault processing, since they should never be replacing one VSID with another using the same ESID. I.e. there's no risk for inserting duplicate entries due to a failed slbie of the old entry. So as long as we clear it out on context switch we should be fine.

I think most people who care know that by now. The rest probably cant even understand the hex output. Since we might have misconfigured firmware or cpus that have a linesize that isnt 128 bytes, I still print it out for those cases. If people would prefer to remove it completely, lets do it. Also for lpar remove the htab_address printout since its not used.

It turns out SLAB has a 2 second per cpu timer that causes this. After switching to SLUB I see some nice 4 second sleeps which is the limit on this POWER6 box (the decrementer ticks at 512MHz): slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 3.96 sec slept 3.80 sec slept 2.99 sec Since SLUB is now the default and some powerpc defconfigs already enable it, lets enable SLUB across the board for consistency. While doing this I also noticed that the maple defconfig has SLAB debugging enabled which is sure to make your box nice and slow. Fix that too.
