2014-05-15goldfish: clean up the pipe driver 64bit ifdefsAlan
Use the 64bit helper method to scrub most of the ifdefs from the driver. The pipe reading has a funny case we can't scrub completely. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-01-24goldfish: add QEMU pipe driverDavid 'Digit' Turner
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: Xin, Xiaohui <xiaohui.xin@intel.com> Signed-off-by: Jiang, Yunhong <yunhong.jiang@intel.com> Signed-off-by: Nakajima, Jun <jun.nakajima@intel.com> [Ported to 3.6] Signed-off-by: Tom Keel <thomas.keel@intel.com> [Ported to 3.7, moved to platform/goldfish] Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
