Subject: [PATCH v19 070/130] KVM: TDX: TDP MMU TDX support
Date: Mon, 26 Feb 2024 00:26:12 -0800 [thread overview]
Message-ID: <56cdb0da8bbf17dc293a2a6b4ff74f6e3e034bbd.1708933498.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1708933498.git.isaku.yamahata@intel.com>
From: Isaku Yamahata <isaku.yamahata@intel.com>
Implement hooks of TDP MMU for TDX backend. TLB flush, TLB shootdown,
propagating the change private EPT entry to Secure EPT and freeing Secure
EPT page. TLB flush handles both shared EPT and private EPT. It flushes
shared EPT same as VMX. It also waits for the TDX TLB shootdown. For the
hook to free Secure EPT page, unlinks the Secure EPT page from the Secure
EPT so that the page can be freed to OS.
Propagate the entry change to Secure EPT. The possible entry changes are
present -> non-present(zapping) and non-present -> present(population). On
population just link the Secure EPT page or the private guest page to the
Secure EPT by TDX SEAMCALL. Because TDP MMU allows concurrent
zapping/population, zapping requires synchronous TLB shoot down with the
frozen EPT entry. It zaps the secure entry, increments TLB counter, sends
IPI to remote vcpus to trigger TLB flush, and then unlinks the private
guest page from the Secure EPT. For simplicity, batched zapping with
exclude lock is handled as concurrent zapping. Although it's inefficient,
it can be optimized in the future.
For MMIO SPTE, the spte value changes as follows.
initial value (suppress VE bit is set)
-> Guest issues MMIO and triggers EPT violation
-> KVM updates SPTE value to MMIO value (suppress VE bit is cleared)
-> Guest MMIO resumes. It triggers VE exception in guest TD
-> Guest VE handler issues TDG.VP.VMCALL<MMIO>
-> KVM handles MMIO
-> Guest VE handler resumes its execution after MMIO instruction

v19:
- Compile fix when CONFIG_HYPERV != y.
It's due to the following patch. Catch it up.
https://lore.kernel.org/all/20231018192325.1893896-1-seanjc@google.com/
- Add comments on tlb shootdown to explan the sequence.
- Use gmem_max_level callback, delete tdp_max_page_level.
v18:
- rename tdx_sept_page_aug() -> tdx_mem_page_aug()
- checkpatch: space => tab
v15 -> v16:
- Add the handling of TD_ATTR_SEPT_VE_DISABLE case.
v14 -> v15:
- Implemented tdx_flush_tlb_current()
- Removed unnecessary invept in tdx_flush_tlb(). It was carry over
from the very old code base.
