This changes arch/powerpc/kernel/smp.c so that if smp_ops->message_pass is NULL, it calls smp_muxed_ipi_message_pass directly. This means that a platform doesn't need to set both .message_pass and .cause_ipi, only one of them. It is a slight performance improvement in that it gets rid of an indirect function call at the expense of a predictable conditional branch.

We expect this is actually faster, and we end up needing more space than we can get from the SPRGs in some instances. This is also useful when running as a guest OS - SPRGs4-7 do not have guest versions. 8 slots are allocated in thread_info for this even though we only actually use 4 of them - this allows space for future code to have more scratch space (and we know we'll need it for things like hugetlb).

The following steps need to be performed to make an hcall: 1. Load r11 with the hcall number 2. Load specific other registers with parameters 3. Issue instrucion "sc 1" 4. The return code is in r3 5. Other returned parameters are in other registers. To provide this service to the kernel, these steps are wrapped in inline assembly functions.

This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls.

If on top of that we do a full table walk, we get rid of all recursive TLB faults, and can dispense with some state saving. This gains a few percent on TLB-miss-heavy workloads, and around 50% on a benchmark that had a high rate of virtual page table faults under the normal handler. While touching the EX_TLB layout, remove EX_TLB_MMUCR0, EX_TLB_SRR0, and EX_TLB_SRR1 as they're not used.

However, this is really just a transport to the service processor which implements them either as "raw" console (networked consoles, HMC, ...) or as "hvsi" serial ports. The later is a simple packet protocol on top of the raw character interface that is supposed to convey additional "serial port" style semantics. In practice however, all it does is provide a way to read the CD line and set/clear our DTR line, that's it. We currently implement the "raw" protocol as an hvc console backend (/dev/hvcN) and the "hvsi" protocol using a separate tty driver (/dev/hvsi0). However this is quite impractical. The arbitrary difference between the two type of devices has been a major source of user (and distro) confusion. Additionally, there's an additional mini -hvsi implementation in the pseries platform code for our low level debug console and early boot kernel messages, which means code duplication, though that low level variant is impractical as it's incapable of doing the initial protocol negociation to establish the link to the FSP. This essentially replaces the dedicated hvsi driver and the platform udbg code completely by extending the existing hvc_vio backend used in "raw" mode so that: - It now supports HVSI as well - We add support for hvc backend providing tiocm{get,set} - It also provides a udbg interface for early debug and boot console This is overall less code, though this will only be obvious once we remove the old "hvsi" driver, which is still available for now. When the old driver is enabled, the new code still kicks in for the low level udbg console, replacing the old mini implementation in the platform code, it just doesn't provide the higher level "hvc" interface. In addition to producing generally simler code, this has several benefits over our current situation: - The user/distro only has to deal with /dev/hvcN for the hypervisor console, avoiding all sort of confusion that has plagued us in the past - The tty, kernel and low level debug console all use the same code base which supports the full protocol establishment process, thus the console is now available much earlier than it used to be with the old HVSI driver. The kernel console works much earlier and udbg is available much earlier too. Hackers can enable a hard coded very-early debug console as well that works with HVSI (previously that was only supported for the "raw" mode). I've tried to keep the same semantics as hvsi relative to how I react to things like CD changes, with some subtle differences though: - I clear DTR on close if HUPCL is set - Current hvsi triggers a hangup if it detects a up->down transition on CD (you can still open a console with CD down). My new implementation triggers a hangup if the link to the FSP is severed, and severs it upon detecting a up->down transition on CD.

All other sections except init were removed in v2.6.15 by 6c45ab992e4299c869fb26427944a8f8ea177024 (powerpc: Remove section free() and linker script bits), and therefore the bulk of the executed code is identical. This patch also removes updating ppc_md.progress to NULL in the powermac late_initcall.

If not we can fall back to setting the mask directly. This resolves an issue with how to sequence the setting of a DMA mask for platform devices. Before we had an issue in that we have no way of setting the DMA mask before the various low level bus notifiers get called that might check it (swiotlb). So now we can do: pdev = platform_device_alloc("foobar", 0); dma_set_mask(&pdev->dev, DMA_BIT_MASK(37)); platform_device_add(pdev); And expect the right thing to happen with the bus notifiers get called via platform_device_add.
