Linux 5.14 To Begin Enabling The Intel Graphics TTM Memory Management Bits for dGPUs

Sun, 06/13/2021 - 19:07
While a decade ago Intel's open-source Linux graphics driver engineers resisted TTM at the time and instead devised the Graphics Execution Manager (GEM) for kernel graphics memory management needs in its place, now with discrete graphics cards and dedicated video memory, Intel has been working on making use of TTM memory management for those purposes. With Linux 5.14 the initial bits are going to be there for using TTM by the Intel driver when running with discrete graphics having local memory...

Profile Guided Optimizations (PGO) Likely Coming To Linux 5.14 For Clang

Sat, 06/12/2021 - 21:00
Recently the mainline Linux kernel has seen a lot of improvements to its feature set when compiling it under LLVM's Clang rather than GCC as traditionally the only supported compiler. The most recent feature being brought to the Linux kernel when using Clang is finally allowing the use of compiler profile guided optimizations (PGO) for squeezing even greater performance out of the system by letting the compiler leverage the real-world profiles/metrics collected to make more informed code generation / optimization decisions...

Real-Time Support "PREEMPT_RT" For Linux Held Up Due To Lack Of Funding

Fri, 06/11/2021 - 19:00
