Additionally I don’t know how many of you can get or read the PC Pro publication. However in one of their issues last year they were providing options for what people can do when Windows 10 comes to the end of its support lifecycle.
One of the options was to switch to Linux they only mentioned Ubuntu Linux and Linux Mint. Though that doesn’t preclude people switching to RHEL on their ex-Windows 10 computers when that point is reached. Though there’s the options of RHEL 8 and RHEL 9 it would be advantageous in several respects including environmental ones, to take it into account for RHEL 10. It may even be a basis for a conversion campaign involving compatible systems that were once Windows 10, to promote conversion from Windows 10 to RHEL 10.
Just think of the irony of going from Windows 10 to RHEL 10 as your new operating system on the computer!

Hi,
I would also like to voice my concerns about requiring x86_64-v3 for RHEL 10.
In the blog post https://developers.redhat.com/articles/2024/01/02/exploring-x86-64-v3-red-ha... Florian writes:
"... and adopting x86-64-v3 will exclude some systems from being able to run RHEL 10, just as the choice of x86-64-v2 for RHEL 9 excluded some systems."
I would like to point out a major difference between what was done on RHEL 9 and what is now planned for 10: the last CPU core designs that did not include support for x86_64-v2 were Intel Cedar Trail and AMD Bobcat. While it is hard to find reliable discontinuation dates, it looks to me like they were both discontinued in 2014. So when RHEL 9 was released in 2022, the affected systems were already 8 years or older. So they were already aging systems.
With the plans for RHEL 10 this is a completely different matter: as Florian writes in the blogpost, Intel still released new CPU variants without support for x86-64-v3 in 2023 so it is very likely that new CPUs without x86-64-v3 will be still sold by the time RHEL 10 will be released. This is of course in addition to the systems sold in the last years without x86-64-v3 and that won't be able to upgrade.
I don't think it is a good idea to raise the minimum requirements so much that even systems sold as new don't meet them.
Also the impacts of such a decision on the environment should be considered. When you believe for example the figures in https://www.tomshardware.com/software/windows/microsofts-draconian-windows-1... then the hardware requirements decided on by Microsoft for Windows 11 alone will lead to hundred thousands of tons of additional electronic waste. I think Linux vendors should set a better example in this regard.
It is these two points that lead me to believe that the raising the baseline to x86-64-v3 should not be implemented in RHEL 10. Instead further research&development should go into hwcaps and should then be reviewed by the time RHEL 11 will be branched.
Kind regards,
Gerd
