(remove change to another file that escaped into the patch set) From: Mike Lockwood <lockwood@google.com> Provide a simple audio channel between the kernel and the emulator that host sit. Queued for staging right now as this ought to be an ALSA driver not just a dumb device of its own making. Signed-off-by:

David 'Digit' Turner authored
A QEMU pipe is a very fast communication channel between the guest system and the emulator. Usage from the guest is simply something like; // connect to special device fd = open("/dev/qemu_pipe", O_RDWR); // tell which service we want to talk to (must be zero-terminated) write(fd, "pipeName", strlen("pipeName")+1); // do read()/write() through fd now ... // close channel close(fd); Signed-off-by:David 'Digit' Turner <digit@android.com> [Added support for parameter buffers for speed] igned-off-by:

Jun Nakajima authored
This imports the current Google code and cleans it up slightly to use pr_ and to properly request its resources. Goldfish is an emulator used for Android development. It has a virtual bus where the emulator passes platform device information to the guest which then creates the appropriate devices. This part of the emulation is not architecture specific so should not be hiding in architecture trees as it does in the Google Android tree. The constants it uses do depend on the platform and the platform creates the bus device which then talks to the emulator to ascertain the actual devices present. Signed-off-by:

On the client side, we have a virtual hcd driver, there actually no hardware interrupts, so we do not need worry about race conditions caused by irq with spinlock held. Turning off irq is not good for system performance after all. Just replace them with a non interrupt safe version. Signed-off-by:

The function 'usbip_event_add()' may be called in interrupt context on the stub side: 'stub_complete'->'stub_enqueue_ret_unlink'->'usbip_event_add'. In this function it tries to get the lock 'ud->lock', so we should disable irq when we get this lock in process context. Signed-off-by:

et131x_get_regs() calls et131x_mii_read(), passing the address of a u32 which is cast to a (u16 *). This works fine for little endian systems, but not for big endian. Change so that the types are cast, not pointers to the types. Reported-by:

The postconfig for drivers that support async commands currently can BUG_ON if the subdevice was improperly configured by the driver. Change the BUG_ON so that a dev_warn() is output and the postconfig returns -EINVAL. This will prevent the comedi core from attaching to the faulty driver but does not BUG the kernel. Signed-off-by:
