This patch adds the habanalabs skeleton driver. The driver does nothing at this stage except very basic operations. It contains the minimal code to insmod and rmmod the driver and to create a /dev/hlX file per PCI device.

When creating or tearing down a transaction, the binder driver examines objects in the buffer and takes appropriate action.

Avoid vm_area when copying to or from binder buffers. Instead, new copy functions are added that copy from kernel space to binder buffer space. These use kmap_atomic() and kunmap_atomic() to create temporary mappings and then memcpy() is used to copy within that page. Also, kmap_atomic() / kunmap_atomic() use the appropriate cache flushing to support VIVT cache architectures. Allow binder to build if CPU_CACHE_VIVT is defined. Several uses of the new functions are added here. More to follow in subsequent patches. Signed-off-by: NTodd Kjos <tkjos@google.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>

The binder driver uses a vm_area to map the per-process binder buffer space. For 32-bit android devices, this is now taking too much vmalloc space. This patch removes the use of vm_area when copying the transaction data from the sender to the buffer space. Instead of using copy_from_user() for multi-page copies, it now uses binder_alloc_copy_user_to_buffer() which uses kmap() and kunmap() to map each page, and uses copy_from_user() for copying to that page.

This patch adds support to compute context invoke method on the remote processor (DSP). This involves setting up the functions input and output arguments, input and output handles and mapping the dmabuf fd for the argument/handle buffers. The below diagram depicts invocation of a single method where the client and objects reside on different processors. An object could expose multiple methods which can be grouped together and referred to as an interface. ,--------, ,------, ,-----------, ,------, ,--------, | | method | | | | | | method | | | Client |------->| Stub |->| Transport |->| Skel |------->| Object | | | | | | | | | | | `--------` `------` `-----------` `------` `--------` Client: Linux user mode process that initiates the remote invocation Stub: Auto generated code linked in with the user mode process that takes care of marshaling parameters Transport: Involved in carrying an invocation from a client to an object. This involves two portions: 1) FastRPC Linux kernel driver that receives the remote invocation, queues them up and then waits for the response after signaling the remote side. 2) Service running on the remote side that dequeues the messages from the queue and dispatches them for processing. Skel: Auto generated code that takes care of un-marshaling parameters Object: Method implementation Most of the work is derived from various downstream Qualcomm kernels.

In the original code before 181bf1e8 the loop was continuing until it finds the first matching superios[i].io and p->base. But after 181bf1e8 the logic changed and the loop now returns the pointer to the first mismatched array element which is then used in get_superio_dma() and get_superio_irq() and thus returning the wrong value. Fix the condition so that it now returns the correct pointer.

Pull powerpc fixes from Michael Ellerman: "Just two fixes, both going to stable. - Our support for split pmd page table lock had a bug which could lead to a crash on mremap() when using the Radix MMU (Power9 only). - A fix for the PAPR SCM driver (nvdimm) we added last release, which had a bug where we might mis-handle a hypervisor response leading to us failing to attach the memory region. Thanks to: Aneesh Kumar K.V, Oliver O'Halloran" * tag 'powerpc-5.0-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/papr_scm: Use the correct bind address powerpc/radix: Fix kernel crash with mremap()
