Subject: [PATCH v4 0/8] Implement generic cc_platform_has() helper function
Date: Tue, 28 Sep 2021 21:10:01 +0200 [thread overview]
Message-ID: <20210928191009.32551-1-bp@alien8.de> (raw)
From: Borislav Petkov <bp@suse.de>
Hi all,
here's v4 of the cc_platform_has() patchset with feedback incorporated.
I'm going to route this through tip if there are no objections.
Thx.
Tom Lendacky (8):
x86/ioremap: Selectively build arch override encryption functions
arch/cc: Introduce a function to check for confidential computing
features
x86/sev: Add an x86 version of cc_platform_has()
powerpc/pseries/svm: Add a powerpc version of cc_platform_has()
x86/sme: Replace occurrences of sme_active() with cc_platform_has()
x86/sev: Replace occurrences of sev_active() with cc_platform_has()
x86/sev: Replace occurrences of sev_es_active() with cc_platform_has()
treewide: Replace the use of mem_encrypt_active() with
cc_platform_has()
