Date: Sun, 12 Sep 2021 22:13:10 -0400 From: Mukul Joshi <mukul.joshi@....com> To: <linux-edac@...r.kernel.org>, <x86@...nel.org> CC: <linux-kernel@...r.kernel.org>, <bp@...en8.de>, <mingo@...hat.com>, <mchehab@...nel.org>, <yazen.ghannam@....com>, <amd-gfx@...ts.freedesktop.org>, Mukul Joshi <mukul.joshi@....com> Subject: [PATCHv2 1/2] x86/MCE/AMD: Export smca_get_bank_type symbol Export smca_get_bank_type for use in the AMD GPU driver to determine MCA bank while handling correctable and uncorrectable errors in GPU UMC. v1->v2: - Drop the function is_smca_umc_v2(). - Drop the patch to introduce a new MCE priority (MCE_PRIO_ACEL) for GPU/accelarator cards.
