samples/vfio-mdev/mtty: expand minor range when registering chrdev region

Actually, total amount of available minor number for a single major is MINORMARK + 1. So expand minor range when registering chrdev region. Signed-off-by: Chengguang Xu Signed-off-by: Alex Williamson

There are new types and helpers that are supposed to be used in new code. As a preparation to get rid of legacy types and API functions do the conversion here. Cc: Kirti Wankhede Cc: Alex Williamson Signed-off-by: Andy Shevchenko Reviewed-by: Christoph Hellwig Signed-off-by: Alex Williamson

vfio-mdev/samples: Use u8 instead of char for handle functions

2018-12-17T18:07:13Z

Clang warns: samples/vfio-mdev/mtty.c:592:39: warning: implicit conversion from 'int' to 'char' changes value from 162 to -94 [-Wconstant-conversion] *buf = UART_MSR_DSR | UART_MSR_DDSR | UART_MSR_DCD; ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~ 1 warning generated. Turns out that all uses of buf in this function ultimately end up stored or cast to an unsigned type. Just use u8, which has the same number of bits but can store this larger number so Clang no longer warns. Signed-off-by: Nathan Chancellor Signed-off-by: Alex Williamson

sample: vfio-mdev: avoid deadlock in mdev_access()

2018-07-11T19:22:41Z

mdev_access() calls mbochs_get_page() with mdev_state->ops_lock held, while mbochs_get_page() locks the mutex by itself. It leads to unavoidable deadlock. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov Signed-off-by: Alex Williamson
