* powerpc: Per process DSCR + some fixes (try#4)Alexey Kardashevskiy2011-04-27
| | | | | | | | | | | | | | | | | | The DSCR (aka Data Stream Control Register) is supported on some server PowerPC chips and allow some control over the prefetch of data streams. This patch allows the value to be specified per thread by emulating the corresponding mfspr and mtspr instructions. Children of such threads inherit the value. Other threads use a default value that can be specified in sysfs - /sys/devices/system/cpu/dscr_default. If a thread starts with non default value in the sysfs entry, all children threads inherit this non default value even if the sysfs value is changed later.

* powerpc/book3e: Flush IPROT protected TLB entries leftover by firmwareJack Miller2011-04-26
| | | | | | | | | | | | | | | | | | | When we set up the TLB for ourselves on Book3E, we need to flush out any old mappings established by the firmware or bootloader. At present we attempt this with a tlbilx to flush everything, but this will leave behind any entries with the IPROT bit set. There are several good reason firmware might establish mappings with IPROT, and in fact ePAPR compliant firmwares are required to establish their initial mapped area with IPROT. This patch, therefore adds more complex code to scan through the TLB upon entry and flush away any entries that are not our own.

* powerpc: Index crit/dbg/mcheck stacks using cpu number on 64bitMichael Ellerman2011-04-26
| | | | | | | | | | | | | | In exc_lvl_ctx_init() we index into the crit/dbg/mcheck stacks using the hard cpu id, but that assumes the hard cpu id is zero based and contiguous. That is not the case on A2. The root of the problem is that the 32bit code has no equivalent of the paca to allow it to do the hard->soft mapping in assembler. Until the 32bit code is updated to handle that, index the stacks using the soft cpu ids on 64bit and hard on 32 bit.

* powerpc/nohash: Allocate stale_map[cpu] on CPU_UP_PREPARE not CPU_ONLINEMichael Ellerman2011-04-20
| | | | | | | | | | | | | | Currently we allocate the stale_map for a cpu when it comes online, this leaves open a small window where a process can be scheduled on the cpu before the stale_map is allocated. Instead allocate the stale_map at CPU_UP_PREPARE time, that way it will be always available before tasks start running. It is possible the cpu fails to come up, in which case we should free the stale_map, so add a CPU_UP_CANCELED case to do that.

* powerpc/boot: Add an ePAPR compliant boot wrapperDavid Gibson2011-04-20
| | | | | | | | | | | | | | | | | | | | This is a first cut at making bootwrapper code which will produce a zImage compliant with the requirements set down by ePAPR. This is a very simple bootwrapper, taking the device tree blob supplied by the ePAPR boot program and passing it on to the kernel. It builds on the earlier patch to build a relocatable ET_DYN zImage to meet the other ePAPR image requirements. For good measure we have some paranoid checks which will generate warnings if some of the ePAPR entry condition guarantees are not met.

* powerpc/boot: Allow building the zImage wrapper as a relocatable ET_DYNMichael Ellerman2011-04-20
| | | | | | | | | | | | | | | | | | | This patch adds code, linker script and makefile support to allow building the zImage wrapper around the kernel as a position independent executable. This results in an ET_DYN instead of an ET_EXEC ELF output file, which can be loaded at any location by the firmware and will process its own relocations to work correctly at the loaded address. This is of interest particularly since the standard ePAPR image format must be an ET_DYN (although this patch alone is not sufficient to produce a fully ePAPR compliant boot image). Note for now we don't enable building with -pie for anything.

* powerpc/mm: Fix slice state initialization for Book3EMichael Ellerman2011-04-20
| | | | | | | | | | | | | | On Book3E, MMU_NO_CONTEXT != 0, but the slice_mm_new_context() macro assumes that it is. This means that the map of the page sizes for each slice is always initialized to zeroes (which happens to be 4k pages), rather than to the correct default base page size value - which might be 64k.

* powerpc: Call CPU ->restore callback earlier on secondary CPUsBenjamin Herrenschmidt2011-04-19
| | | | | | | | | | | | | We do it before we loop on the PACA start flag. This way, we get a chance to set critical SPRs on all CPUs before Linux tries to start them up, which avoids problems when changing some bits such as LPCR bits that need to be identical on all threads of a core or similar things like that. Ideally, some of that should also be done before the MMU is enabled, but that's a separate issue which would require moving some of the SMP startup code earlier, let's not get there for now, it works with that change alone.

| | | | | | | | | | | | This uses feature sections to arrange that we always use HSPRG1 as the scratch register in the interrupt entry code rather than SPRG2 when we're running in hypervisor mode on POWER7. This will ensure that we don't trash the guest's SPRG2 when we are running KVM guests. To simplify the code, we define GET_SCRATCH0() and SET_SCRATCH0() macros like the GET_PACA/SET_PACA macros.

| | | | | | | | | When running in Hypervisor mode (arch 2.06 or later), we store the PACA in HSPRG0 instead of SPRG1.

* powerpc/xics: Rewrite XICS driverBenjamin Herrenschmidt2011-04-19
| | | | | | | | | | | | | | | | This is a significant rework of the XICS driver, too significant to conveniently break it up into a series of smaller patches to be honest. The driver is moved to a more generic location to allow new platforms to use it, and is broken up into separate ICP and ICS "backends". For now we have the native and "hypervisor" ICP backends and one common RTAS ICS backend. The driver supports one ICP backend instanciation, and many ICS ones, in order to accomodate future platforms with multiple possibly different interrupt "sources" mechanisms.

At present, remotes with an images or photos or pictures button use any number of different keycodes which sort of maybe fit. I've seen at least KEY_MEDIA, KEY_CAMERA, KEY_GRAPHICSEDITOR and KEY_PRESENTATION. None of those seem quite right. In my mind, KEY_MEDIA should be something more like a media center application launcher (and I'd like to standardize on that for things like the windows media center button on the mce remotes). KEY_CAMERA is used in a lot of webcams, and typically means "take a picture now". KEY_GRAPHICSEDITOR implies an editor, not a browser. KEY_PRESENTATION might be the closest fit here, if you think "photo slide show", but it may well be more intended for "run application in full-screen presentation mode" or to launch something like magicpoint, I dunno. And thus, I'd like to have a KEY_IMAGES, which matches the HID Usage AL Image Browser, the meaning of which I think is crystal-clear. I believe AL Audio Browser is already covered by KEY_AUDIO, and AL Movie Browser by KEY_VIDEO, so I'm also adding appropriate comments next to those keys.
