And according to the change list of the Linux kernel, Ironically, Intel is removing support Cannon Lake graphics driver for the upcoming Linux kernel version 5.15.These chips are famously shipped no The integrated graphics engine is active, which means that a graphics driver is not even required.Interestingly, the chip Have done It has an integrated 10th-generation graphics engine, but Intel has disabled graphics, which indicates that there is a yield problem with its 10-nanometer process, but it is not fully disclosed. In fact, Intel also restricts these chips to the Chinese region to keep it away from Western audiences. What followed was a long list of further 10nm delays, which gave its competitor AMD a huge advantage, while Intel has not fully recovered from the impact.
In addition to the DG2 activation code, the biggest news may be the cancellation of support for Intel Cannon Lake graphics. In the upcoming Linux kernel version 5.15, the i915 GFX driver will no longer support Cannon Lake graphics. This means that Intel considers Cannon Lake’s graphics driver as a bloated complement to the i915 GFX driver, and therefore deleted it. The driver is not important anyway-the graphics engine has never worked.
exist Latest PR For the Linux kernel version 5.15 submitted by the Intel development team, we also saw a fairly comprehensive list of changes being submitted by the company. With a lot of work going on, it seems that most of the work is happening on the graphical front end of the driver stack.
In the list, we can see that there are also fixes DG1 GPU For example, refactoring DG1 interrupt handler, repairing DG1 memory bandwidth calculation, etc. In addition to the DG1 code, we are also seeing more and more enabling codes for the upcoming DG2 graphics card series. This is usually a good indicator of an upcoming release, because Linux is one of the first packages to receive support for the new architecture.
