Was hoping to get some updated instructions for this. Have access to a dedicated server. The info on the web seems to be outdated.....some of the links are DOA..... There was one simple install, but not sure if it would work: This tutorial explains how to install icecast kh10 server on centos 6 server # cd /usr/src # wget

Hi, This is a batch of patches touching drm for preparing for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add

Some graphics APIs differentiate between out-of-graphics-memory and out-of-host-memory (system memory). Add a device init flag to have -ENOSPC propagated from the resource managers instead of being converted to -ENOMEM, to aid driver stacks in determining what error code to return or whether corrective action can be taken at the driver level. The first patch deals with a ttm_device_init()
