Re: [PATCH] cxl: Add kernel API to allow a context to operate with relocate disabled

Sure thing, that actually simplifies things a great deal. Testing now and will resend shortly :) -Ian ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

Re: [PATCH] cxl: Add kernel API to allow a context to operate with relocate disabled

Hi Ian, The principle is fine, but the cxl_start_context2 API bothers me a bit. Would something similar to this make sense, I think it would keep the API cleaner: /* new kernel-only API */ void cxl_set_translation_mode(struct cxl_context *ctx, bool real_mode) For mlx5, the call sequence

[PATCH] cxl: Add kernel API to allow a context to operate with relocate disabled

From: Ian Munsie cxl devices typically access memory using an MMU in much the same way as the CPU, and each context includes a state register much like the MSR in the CPU. Like the CPU, the state register includes a bit to enable relocation, which we currently always enable.
