The qe_brg structure manually defined each of the 16 BRG registers, which made any code that used them cumbersome. This patch replaces the fields with a single 16-element array. Signed-off-by:

bad_page_fault() prints a message telling the user what type of bad fault we took. The first line of this message is currently implemented as two separate printks. This has the unfortunate effect that if several cpus simultaneously take a bad fault, the first and second parts of the printk get jumbled up, which looks dodge and is hard to read. So do a single one-line printk for each fault type. Signed-off-by:

* Cleaned up interrupt mapping a little by adding a helper function which parses the irq out of the device-tree, and puts it into a resource. * Changed the arch/ppc platform files to specify PHY_POLL, instead of -1 * Changed the fixed phy to use PHY_IGNORE_INTERRUPT * Added ethtool.h and mii.h to phy.h includes Signed-off-by: -

This patch adds a command to xmon for dumping information about spu structs. The command is 'sf' for "spu fields" perhaps, and takes the spu number as an argument. This is the same value as the spu->number field, or the "phys-id" value of a context when it is bound to a physical spu. We try to catch memory errors as we dump each field, hopefully this will make the command reasonably robust, but YMMV. If people see a need we can easily add more fields to the dump in future. Output looks something like this: 0:mon> sf 0 Dumping spu fields at address c00000001ffd9e80: number = 0x0 name = spe devnode->full_name = /cpus/PowerPC,BE@0/spes/spe@0 nid = 0x0 local_store_phys = 0x20000000000 local_store = 0xd0000800801e0000 ls_size = 0x0 isrc = 0x4 node = 0x0 flags = 0x0 dar = 0x0 dsisr = 0x0 class_0_pending = 0 irqs[0] = 0x16 irqs[1] = 0x17 irqs[2] = 0x24 slb_replace = 0x0 pid = 0 prio = 0 mm = 0x0000000000000000 ctx = 0x0000000000000000 rq = 0x0000000000000000 timestamp = 0x0000000000000000 problem_phys = 0x20000040000 problem = 0xd000080080220000 problem->spu_runcntl_RW = 0x0 problem->spu_status_R = 0x0 problem->spu_npc_RW = 0x0 priv1 = 0xd000080080240000 priv1->mfc_sr1_RW = 0x33 priv2 = 0xd000080080250000 Signed-off-by:

This patch adds support for stopping, and restarting, spus from xmon. We use the spu master runcntl bit to stop execution, this is apparently the "right" way to control spu execution and spufs will be changed in the future to use this bit. Testing has shown that to restart execution we have to turn the master runcntl bit on and also rewrite the spu runcntl bit, even if it is already set to 1 (running). Stopping spus is triggered by the xmon command 'ss' - "spus stop" perhaps. Restarting them is triggered via 'sr'. Restart doesn't start execution on spus unless they were running prior to being stopped by xmon. Walking the spu->full_list in xmon after a panic, would mean corruption of any spu struct would make all the others inaccessible. To avoid this, and also to make the next patch easier, we cache pointers to all spus during boot. We attempt to catch and recover from errors while stopping and restarting the spus, but as with most xmon functionality there are no guarantees that performing these operations won't crash xmon itself.

This moves the cell idle function to use the default cpu_idle with a special power_save callback, like all other platforms except iSeries already do. It also makes it possible to disable this power_save function with a new powerpc-specific boot option "powersave=off". Signed-off-by:

This patch adds a module that registers sysfs attributes to CPU and SPU containing the temperature of the CBE. They can be found under /sys/devices/system/spu/cpuX/thermal/temperature[0|1] /sys/devices/system/spu/spuX/thermal/temperature The temperature is read from the on-chip temperature sensors.

This patch adds two functions to create and remove sysfs attributes and attribute_group to all cpus. That allows to register sysfs attributes in a subdirectory like: /sys/devices/system/cpu/cpuX/group_name/what_ever This will be used by cbe_thermal to group all attributes dealing with thermal support in one directory.

In order to add sysfs attributes to all spu's, there is a need for a list of all available spu's. Adding the device_node makes also sense, as it is needed for proper register access. This patch also adds two functions to create and remove sysfs attributes and attribute_groups to all spus. That allows to group spu attributes in a subdirectory like: /sys/devices/system/spu/spuX/group_name/what_ever This will be used by cbe_thermal to group all attributes dealing with thermal support in one directory.

Many of the registers in the performance monitoring unit are write-only. We need to save a "shadow" copy when we write to those registers so we can retrieve the values if we need them later. The new cbe_pmd_shadow_regs structure is added to the cbe_regs_map structure so we have the appropriate per-node copies of these shadow values. Signed-off-by:

When in isolated mode, SPEs have access to an area of persistent storage, which is per-SPE. In order for isolated-mode apps to communicate arbitrary data through this storage, we need to ensure that isolated physical SPEs can be reused for subsequent applications. Add a file ("recycle") in a spethread dir to enable isolated-mode recycling. By writing to this file, the kernel will reload the isolated-mode loader kernel, allowing a new app to be run on the same physical SPE. This requires the spu_acquire_exclusive function to enforce exclusive access to the SPE while the loader is initialised. Signed-off-by:Jeremy Kerr <jk@ozlabs.org> Signed-off-by:

This patch adds general support for isolated mode SPE apps. Isolated apps are started indirectly, by a dedicated loader "kernel". This patch starts the loader when spe_create is invoked with the ISOLATE flag. We do this at spe_create time to allow libspe to pass the isolated app in before calling spe_run. The loader is read from the device tree, at the location "/spu-isolation/loader". If the loader is not present, an attempt to start an isolated SPE binary will fail with -ENODEV. Update: loader needs to be correctly aligned - copy to a kmalloced buf. Update: remove workaround for systemsim/spurom 'L-bit' bug, which has been fixed. Update: don't write to runcntl on spu_run_init: SPU is already running. Update: do spu_setup_isolated earlier Tested on systemsim. Signed-off-by: -

This adds two new flags to spu_create: SPU_CREATE_NONSCHED: create a context that is never moved away from an SPE once it has started running. This flag can only be used by tasks with the CAP_SYS_NICE capability. SPU_CREATE_ISOLATED: create a nonschedulable context that enters isolation mode upon first run. This requires the SPU_CREATE_NONSCHED flag. Signed-off-by:

SPRN_SDR1 and the SPE's MFC SDR are hypervisor resources and are not accessible from a logical partition. This change adds an access wrapper. When running on bare H/W, the spufs needs to only set the SPE's MFC SDR to the value of the PPE's SPRN_SDR1 once at SPE initialization, so this change renames mfc_sdr_set() to mfc_sdr_setup() and moves the access of SPRN_SDR1 into the mmio wrapper. It also removes the now unneeded member mfc_sdr_RW from struct spu_priv1_collapsed. Signed-off-by:

Remove the iSeries initrd logic, instead just store the initrd location and size in the device tree so generic code can do the rest for us. The iSeries code had a "feature" which the generic code lacks, ie. if the compressed initrd is bigger than the configured ram disk size, we make the ram disk size bigger. That's bogus, as the compressed size of the initrd tells us nothing about how big the ram disk needs to be. If the ram disk isn't big enough you just need to make CONFIG_BLK_DEV_RAM_SIZE larger.

The original problem that inspired this patch was solved quite some time ago (Turning off PCI didn't work), but this patch neatens things up a little (I think), by putting all the PCI stuff inside a single CONFIG_PCI block. It also removes the OF PCI bus matching entries if CONFIG_PCI is off. Signed-off-by:
