* staging: android: binder: fix binder interface for 64bit compat layerSerban Constantinescu2013-07-231-6/+6
| | | | | | | | | | | | | | | | | | | | | | The changes in this patch will fix the binder interface for use on 64bit machines and stand as the base of the 64bit compat support. The changes apply to the structures that are passed between the kernel and userspace. Most of the changes applied mirror the change to struct binder_version where there is no need for a 64bit wide protocol_version(on 64bit machines). The change inlines with the existing 32bit userspace(the structure has the same size) and simplifies the compat layer such that the same handler can service the BINDER_VERSION ioctl. Other changes make use of kernel types as well as user-exportable ones and fix format specifier issues. The changes do not affect existing 32bit ABI.

* staging: android: binder: replace types with portable onesSerban Constantinescu2013-07-231-13/+13
| | | | | | | | | | | | | | | Since this driver is meant to be used on different types of processors and a portable driver should specify the size a variable expects to be this patch changes the types used throughout the binder interface. We use "userspace" types since this header will be exported and used by the Android filesystem. The patch does not change in any way the functionality of the binder driver.

* staging: android: binder: fix BC_FREE_BUFFER ioctl declarationSerban Constantinescu2013-07-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | BinderDriverCommands mirror the ioctl usage. Thus the size of the structure passed through the interface should be used to generate the ioctl No. The change reflects the type being passed from the user space-a pointer to a binder_buffer. This change should not affect the existing 32bit user space since BC_FREE_BUFFER is computed as: #define _IOW(type,nr,size) \ ((type) << _IOC_TYPESHIFT) | \ ((nr) << _IOC_NRSHIFT) | \ ((size) << _IOC_SIZESHIFT)) and for a 32bit compiler BC_FREE_BUFFER will have the same computed value. This change will also ease our work in differentiating BC_FREE_BUFFER from COMPAT_BC_FREE_BUFFER. The change does not affect existing 32bit ABI.

* staging: android: binder: fix BINDER_SET_MAX_THREADS declarationSerban Constantinescu2013-07-231-1/+1
| | | | | | | | | | | | | | | | This change will fix the BINDER_SET_MAX_THREADS ioctl to use __u32 instead of size_t for setting the max threads. Thus using the same handler for 32 and 64bit kernels. This value is stored internally in struct binder_proc and set to 15 on open_binder() in the libbinder API(thus no need for a 64bit size_t on 64bit platforms). The change does not affect existing 32bit ABI.

* staging: android: binder: modify struct binder_write_read to use size_tSerban Constantinescu2013-07-231-4/+4
| | | | | | | | | | | | | | This change mirrors the userspace operation where struct binder_write_read members that specify the buffer size and consumed size are size_t elements. The patch also fixes the binder_thread_write() and binder_thread_read() functions prototypes to conform with the definition of binder_write_read. The changes do not affect existing 32bit ABI.

| | | | | | | | | | | | | | This reverts commit b0a0ccfad85b3657fe999805df65f5cfe634ab8a. Turns out I was wrong, we want these in the tree. Note, I've disabled the drivers from the build at the moment, so other patches can be applied to fix some build issues due to internal api changes since the code was removed from the tree.

It builds, but not as a module, and with lots of warnings.
