[edk2] [PATCH 0/1] OvmfPkg/QemuFwCfgDxeLib: SEV: zero FW_CFG_DMA_ACCESS before decrypting it

Posted by Laszlo Ersek 6 years, 7 months ago

This crossed my mind previously in
<http://mid.mail-archive.com/1d6bade7-578e-c0e7-5aa6-2ca6af1185e6@redhat.com>,
point (4), and now I thought I should search for
EdkiiIoMmuOperationBusMasterCommonBuffer too, not just
VirtioOperationBusMasterCommonBuffer.

Repo:   https://github.com/lersek/edk2.git
Branch: fwcfg_sev_commonbuffer
