Re: 64-bit operating system

Just so you know. Thunking is the term for communicating between drivers in separate spaces.

None of this has to do with how much memory a system can address nor the amount of bits.

Re: 64-bit operating system

My point about the pinouts was not really about them. They are great. I was pointing out that different levels of compatibility exist and used them as an example. Regardless of any one piece of the pi's adoption, pieces evolve. At some point delineations happen in both software and hardware. If you ...

Re: 64-bit operating system

Is everything a cost/use analysis? Are you asking these questions to get answers or to quiet the rhetoric? Yes. Everything is subject to a cost/benefit analysis. Doing anything else is an invitation to bankruptcy. Need I remind you that Eben Upton has an MBA in addition to his Comp. Sci. PhD? I cam...

Re: 64-bit operating system

You are not answering the questions, just attempting to justify Debian ARM64 without a cost / use analysis, heck the RPF do not even offer a Debian x86-64 for PC/MAC ! This type of post has been around for nigh on 3 years so the RPF/RPT are well aware of the pros and cons...... How am I supposed to...

Re: 64-bit operating system

The RPF / RPT would have to support 2 Operating Systems, who pays the cost of the extra man hours required ??? How does a Charity justify this expenditure ??? How does this further the charitable aims ??? Utopian Dreams ??? How do they justify any piece of technology they put into it? I bet 90% of ...

Re: 64-bit operating system

You don't need anything. Logically you can build a system with 1 bit logic. An 8bit computer can page out memory and do anything albeit slowly. The BCM2837 is a great chip. It has 64 bit capabilities which expose more registers, sandboxes, addressing modes, etc. Maybe someone wants to see how the di...

Re: 64-bit operating system

Thank you sakaki the gentoo stuff has made a tool available for much of the work I plan to do. I fear when I release it raspbian will probably still not support it. It is sad to see the same old arguments the x86 community when through during the transition to 64. Most of them are basically wrong or...
