Use of the RISC-V instruction set only in a Open-source FPGA design (license question)
I have started to create a VHDL design for new architecture. Now I'm thinking about the used instruction set. Could create an own encoding of the used machine code, but must create a C compiler for it or port the architecture to an existing compiler like GCC. Also must write an assembler, if I use an own instruction set.
What are the license requirements for me as developer, when I want use any specific parts of the RISC-V instruction set only? Would also to add some specific processor control registers and a modified base architecture. Might be security by obscurity, but control registers where I can setup the end of the stack and the size in privileged mode. Also two types of the stack. Return address and data, both separately as example.
BTW: The project is currently for the purpose of education only. Without interest from me to sell this maybe exotic (not RISC-V itself, but my modifications) architecture.

Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ₹43,559 crore at the end of March 2021 compared to the company’s market capitalisation of ₹44,447 crore.
Telegram Auto-Delete Messages in Any Chat
Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
