| | | | | | | | | | | | | | | | | | | | | | | | HVM_PARAM_CONSOLE_PFN is used to retrieved the console PFN for HVM guest. It returns a PFN (aka GFN) and not a MFN. Furthermore, use directly virt_to_gfn for both PV and HVM domain rather than doing a special case for each of the them.

| * xen: Use correctly the Xen memory terminologiesJulien Grall2015-09-081-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on include/xen/mm.h [1], Linux is mistakenly using MFN when GFN is meant, I suspect this is because the first support for Xen was for PV. This resulted in some misimplementation of helpers on ARM and confused developers about the expected behavior. For instance, with pfn_to_mfn, we expect to get an MFN based on the name. Although, if we look at the implementation on x86, it's returning a GFN. For clarity and avoid new confusion, replace any reference to mfn with gfn in any helpers used by PV drivers. The x86 code will still keep some reference of pfn_to_mfn which may be used by all kind of guests No changes as been made in the hypercall field, even though they may be invalid, in order to keep the same as the defintion in xen repo. Note that page_to_mfn has been renamed to xen_page_to_gfn to avoid a name to close to the KVM function gfn_to_page. Take also the opportunity to simplify simple construction such as pfn_to_mfn(page_to_pfn(page)) into xen_page_to_gfn. More complex clean up will come in follow-up patches.

* | powerpc/hvsi: Fix endianness issues in the HVSI driverLaurent Dufour2015-08-201-22/+24
|/ | | | | | | | | | | | | | | | | | | | | | | | This patch fixes several endianness issues detected when running the HVSI driver in little endian mode. These issues are raised in little endian mode because the data exchanged in memory between the kernel and the hypervisor has to be in big endian format. This exhibits as errors such as: irq: (null) didn't like hwirq-0x1000a00 to VIRQ16 mapping (rc=-22) hvsi_console_init: couldn't create irq mapping for 0x1000a00 The data structures already have endian annotations, and sparse is generating numerous warnings based on those. This commit fixes all of them.

It will basically go back to sleep until the timeout is expired (only signals can really wake it).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3e6c6f630a5282df8f3393a59f10eb9c56536d23 ("Delay creation of khcvd thread") moved the call of hvc_init from being a device_initcall into hvc_alloc, and used a non-null hvc_driver as indication of whether hvc_init had already been called. The problem with this is that hvc_driver is only assigned a value at the bottom of hvc_init, and so there is a window where multiple hvc_alloc calls can be in progress at the same time and hence try and call hvc_init multiple times. Previously the use of device_init guaranteed that hvc_init was only called once. This manifests itself as sporadic instances of two hvc_init calls racing each other, and with the loser of the race getting -EBUSY from tty_register_driver() and hence that virtual console fails: Couldn't register hvc console driver virtio-ports vport0p1: error -16 allocating hvc for port Here we add an atomic_t to guarantee we'll never run hvc_init twice.

* drivers/tty/hvc: don't use module_init in non-modular hyp. console codePaul Gortmaker2014-02-074-42/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The HVC_OPAL/RTAS/UDBG/XEN options are all bool, and hence their support is either present or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering. Also the __exitcall functions have been outright deleted since they are only ever of interest to UML, and UML will never be using any of this code.

| | | | | | | | | | | | | | Add the generic "lnxhvc" terminal ID to automatically assign a HVC terminal when connecting to the HVC IUCV terminal device driver. The terminal device driver tries to find a free (not connected) HVC terminal to satisfy the incoming connection request.

The short <blurb> is that the tracing facility (just one function) has been added to SWIOTLB to make it easier to track I/O progress. Additionally under Xen and ARM (32 & 64) the Xen-SWIOTLB driver "is used to translate physical to machine and machine to physical addresses of foreign[guest] pages for DMA operations" (Stefano) when booting under hardware without proper IOMMU. There are also bug-fixes, cleanups, compile warning fixes, etc. The commit times for some of the commits is a bit fresh - that is b/c we wanted to make sure we have the Ack's from the ARM folks - which with the string of back-to-back conferences took a bit of time. Rest assured - the code has been stewing in #linux-next for some time. Features: - SWIOTLB has tracing added when doing bounce buffer. - Xen ARM/ARM64 can use Xen-SWIOTLB. This work allows Linux to safely program real devices for DMA operations when running as a guest on Xen on ARM, without IOMMU support. [*1] - xen_raw_printk works with PVHVM guests if needed. Bug-fixes: - Make memory ballooning work under HVM with large MMIO region. - Inform hypervisor of MCFG regions found in ACPI DSDT. - Remove deprecated IRQF_DISABLED. - Remove deprecated __cpuinit. [*1]: "On arm and arm64 all Xen guests, including dom0, run with second stage translation enabled. As a consequence when dom0 programs a device for a DMA operation is going to use (pseudo) physical addresses instead machine addresses. This work introduces two trees to track physical to machine and machine to physical mappings of foreign pages. Local pages are assumed mapped 1:1 (physical address == machine address). It enables the SWIOTLB-Xen driver on ARM and ARM64, so that Linux can translate physical addresses to machine addresses for dma operations when necessary.
