* [POWERPC] pasemi: Move pasemi_idle_init() to late_initcall()Olof Johansson2007-09-143-5/+7
| | | | | | | | | Move pasemi_idle_init() to be a late_initcall instead of being called from setup_arch(). This way the cpufreq driver has a chance to initialize and save away the boot time astate before we go to idle for the first time.

* [POWERPC] pasemi: Print more information at machine checkOlof Johansson2007-09-141-4/+106
| | | | | | | | | | | | | Add printout of some SoC error status registers, and dump the SLB contents for those machine check events where it makes sense. Since we can't go about and ioremap registers at machine check time, and we generally want to do as little as possible to print out the information, pre-build a table of the registers to dump and their address in the common PCI config space range.

* [POWERPC] pasemi: Add workaround for erratum 5945Olof Johansson2007-09-141-2/+60
| | | | | | | | | | Erratum 5945 causes some of the registers on the PCIe root ports to not read correctly. Do a small dance to avoid this: Write an unused register, read the value and write it back. Thankfully this is not in a hot code path. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Provide a default irq_host match, which matches on an exact of_nodeMichael Ellerman2007-09-144-25/+0
| | | | | | | | | The most common match semantic is an exact match based on the device node. So provide a default implementation that does this, and hook it up if no match routine is specified. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Invert null match behaviour for irq_hostsMichael Ellerman2007-09-143-0/+21
| | | | | | | | | | | | | Currently if you don't specify a match callback for your irq_host it's assumed you match everything. This is a kind of opt-out approach, and turns out to be the exception rather than the rule. So change the semantics to be opt-in, ie. you don't match anything unless you provide a match callback. This in itself isn't very useful, but will allow us to provide a default match implementation in a subsequent patch.

* [POWERPC] Add an optional device_node pointer to the irq_hostMichael Ellerman2007-09-1410-34/+23
| | | | | | | | | | The majority of irq_host implementations (3 out of 4) are associated with a device_node, and need to stash it somewhere. Rather than having it somewhere different for each host, add an optional device_node pointer to the irq_host structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, running any SPE program on the ps3 will trigger a BUG_ON when spufs_run_spu tries to clear the master run control bit, as lv1 does not make the master run control available to Linux. This change makes SPE apps work again by disabling changes to the master run control on PS3. Although we don't have the facility to disable a SPE with supervisor-level privileges, it's better than hitting the BUG_ON unconditionally.

The current spu interrupt handler assumes this behavior and does not clear the interrupt status. The PS3 hypervisor visualizes all SPU interrupts as level, and on return from the interrupt handler the hypervisor will deliver a new virtual interrupt for any unmasked interrupts which for which the status has not been cleared. This fix clears the interrupt status in the interrupt handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a major bug which was happening when a SPU thread advances its execution right after being restored to a SPU. A potentially outdated NPC value was being (re)written to the SPU. So, spu_run_init, in this case, was either not doing anything relevant, or breaking the execution of the SPU thread. This fixes a common problem of losing a mailbox write when it was done to a saved context.

| * [POWERPC] spu_manage: fix spu_unit_number for celleb device treeChristian Krafft2007-08-301-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression introduced with 2.6.23-rc4 after on some confusion about the device tree interfaces. IBM QS21 device trees provide "physical-id", so we changed the code to run on that and remain compatible with all IBM machines. However, the Toshiba Celleb device tree provides the "unit-id" property, which was in the Linux code, but never used in this way on IBM hardware. Legacy device tree used the reg property for the physical id of an spe. This patch fixes find_spu_unit_number to look for the spu id in that order. The length is checked to avoid misinterpretation in case the attributes unit-id or reg do not contain the id.

| * [POWERPC] cell: Support pinhole-reset on IBM cell bladesArnd Bergmann2007-08-252-2/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Cell Broadband Engine has a method of injecting a system-reset-exception from an external source into the operating system, which should trigger the regular behaviour of entering xmon or kdump. Unfortunately, the exception handler cannot distinguish it from other interrupt causes by the SRR1 register, which gets used for this on Power 6 and others. IBM Blade servers that want to support triggering the system reset exception using a pinhole button in the front panel therefore use an extra register to determine the reset cause.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Legacy device tree used the reg property for the physical id of an spe. On newer device tree layouts the reg property contains the "correct" value in the reg attribute. So there has been intoduced the "physical-id" on newer devicetree layouts. The id is stored by spu_manage into the spu struct as spe_id. cbe_thermal has been changed to use the spu->spe_id. There's no need for the thermal code to check devicetree attributes for itself.

Fixed up the device tree's to actual conform for to specification and changed the interrupt mapping code so it just uses a static mapping setup as follows: PIRQA - IRQ9 PIRQB - IRQ10 PIRQC - IRQ11 PIRQD - IRQ12 USB 1.1 OCHI (1c.0) - IRQ12 USB 1.1 OCHI (1c.1) - IRQ9 USB 1.1 OCHI (1c.2) - IRQ10 USB 1.1 ECHI (1c.3) - IRQ11 LAN (1b.0) - IRQ6 AC97 (1d.0) - IRQ6 Modem (1d.1) - IRQ6 HD Audio (1d.2) - IRQ6 SATA (1f.1) - IRQ5 SMB (1e.1) - IRQ7 PMU (1e.2) - IRQ7 PATA (1f.0) - IRQ14/15 Took the oppurtunity to refactor the code into a single file so we don't have to duplicate these fixes on the two current boards in the tree and several forth coming boards that will also need the code. Fixed RTC support that requires a dummy memory read on the P2P bridge to unlock the RTC and setup the default of the RTC alarm registers to match with a basic x86 style CMOS RTC. Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure the PCI IO space has been setup properly before we start poking ISA registers at random locations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove dead code, and a misleading comment about EEH checking for video devices. The removed code is a left-over from the olden days where there was concern over how video devices worked in Linux. We are never going to go that way again, so kill this.

* | | [POWERPC] Remove gratuitous reads from powermac pci config space methodsNathan Lynch2007-08-171-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The powermac pci configuration space write methods read the written location immediately after the write is performed, presumably in order to flush the write. However, configuration space writes are not allowed to be posted, making these reads gratuitous. Furthermore, this behavior potentially causes us to violate the PCI PM spec when changing between e.g. D0 and D3 states, because a delay of up to 10ms may be required before the OS accesses configuration space after the write which initiates the transition. Remove the unnecessary reads from macrisc_write_config, u3_ht_write_config, and u4_pcie_write_config. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
