recent yearsAMDIt's very active in open source, so this time it's also found in the graphics driver submitted by AMD for the Linux kernel. Although the "Navi 14" code has been found in the driver submitted by AMD for the Navi architecture before, in the latest code submission, AMD formally confirmed the existence of the Navi 14 graphics card and has enabled the driver. However, it is noteworthy that the code submitted by AMD is still for Navi 10 graphics cards, that is, the upcoming RX 5700 series.
In this submission code, there are only less than 1400 lines of code about Navi 14 graphics card, a total of 53 submissions, but some device information, including AISC type information, firmware information, etc., has been included, which shows that Navi 14 graphics card really exists. At the same time, as a relatively early code, Navi 14 already includes Golden Setting, for[计] serveThe partial source code of the functions such as the virtual display of the KMS (kernel mode setting). This also shows that the AMD Navi 14 graphics card is already in drive adaptation.

From the frequency of code submission, AMD accelerates the submission of Linux drivers for Navi Series graphics cards. According to Phoronix, AMD may compress the cycle of new graphics card drivers into the Linux 5.3 kernel cycle. Now AMD has started the driver development of Navi 14 graphics cards, which shows that we will see more new graphics cards in the near future.
