4 Intel and AMD 32-bit x86 Intel and AMD 64-bit x86-64 distributions for kernel versions ranging from version up to version 3.8. Power saving modes of the operating systems (StandBy, Sleep, Suspend...) are not supported. Support of Linux Kernel 3.8 Since version , the Virtual File System Drivers support the Linux Kernel 3.8.

5 Intel and AMD 32-bit x86 Intel and AMD 64-bit x86-64 distributions for kernel versions ranging from version up to version Power saving modes of the operating systems (StandBy, Sleep, Suspend...) are not supported. Support of Linux Kernel Since version , the Virtual File System Drivers support the Linux Kernel EURESYS s.a /12

6 Intel and AMD 32-bit x86 Intel and AMD 64-bit x86-64 distributions for kernel versions ranging from version up to version Power saving modes of the operating systems (StandBy, Sleep, Suspend...) are not supported. Multiple access of the same file Kernel error when accessing the same file with several applications. This has been solved in version Note: several applications can access the same file simultaneously. When doing so, it is the application's responsibility to synchronize the file accesses. Audio break down Audio break down on new processors Intel Core i3, i5 and i7. This has been solved in version Configuration of Deinterlacing Filter The Visual Source Deinterlacing Filter is now configurable. Element: DeinterlacingFilter_FIXED, DeinterlacingFilter_ADAPTIVE. Meaning: ADAPTIVE: the deinterlacing filter is enabled when there is movement detected in the image. FIXED: the deinterlacing filter is permanently enabled. See the Visual Source DTD file for more details. EURESYS s.a /12

Simultaneous access to a file from several processes File access may hang the system when performed simultaneously from several processes. This has been solved. EURESYS s.a /12

9 Intel and AMD 32-bit x86 Intel and AMD 64-bit x86-64 distributions for kernel versions ranging from version up to version Power saving modes of the operating systems (StandBy, Sleep, Suspend...) are not supported. Linux kernel support On Linux kernel version (or above), installing the Virtual File System driver does not work. This has been solved. EURESYS s.a /12

10 Intel and AMD 32-bit x86 Intel and AMD 64-bit x86-64 distributions for kernel versions ranging from version up to version New file in /proc A new file has been added in /proc, it lists the installed boards. See documentation for more details. Mounting a non existing board Mounting a non existing board crashes the system. This has been solved. EURESYS s.a /12
