[Xen-devel] [PATCH v8 03/13] arm/lpae: Introduce lpae_is_page helper

This commit introduces a new helper that checks whether the target PTE holds a page mapping or not. This helper will be used as part of the following commits. Signed-off-by: Sergej Proskurin Reviewed-by: Julien Grall --- Cc: Stefano Stabellini

[Xen-devel] [PATCH v8 08/13] arm/guest_access: Move vgic_access_guest_memory to guest_access.h

This commit moves the function vgic_access_guest_memory to guestcopy.c and the header asm/guest_access.h. No functional changes are made. Please note that the function will be renamed in the following commit. Signed-off-by: Sergej Proskurin Acked-by: Julien Grall

[Xen-devel] [PATCH v8 01/13] arm/mem_access: Add and cleanup (TCR_|TTBCR_)* defines

This commit adds (TCR_|TTBCR_)* defines to simplify access to the respective register contents. At the same time, we adjust the macros TCR_T0SZ and TCR_TG0_* by using the newly introduced TCR_T0SZ_SHIFT and TCR_TG0_SHIFT instead of the hardcoded values. Signed-off-by: Sergej Proskurin

[Xen-devel] [PATCH v8 09/13] arm/guest_access: Rename vgic_access_guest_memory

This commit renames the function vgic_access_guest_memory to access_guest_memory_by_ipa. As the function name suggests, the functions expects an IPA as argument. All invocations of this function have been adapted accordingly. Apart from that, we have adjusted all printk messages for cleanup and to

[Xen-devel] [PATCH v8 02/13] arm/mem_access: Add defines supporting PTs with varying page sizes

AArch64 supports pages with different (4K, 16K, and 64K) sizes. To enable guest page table walks for various configurations, this commit extends the defines and helpers of the current implementation. Signed-off-by: Sergej Proskurin Reviewed-by: Julien Grall

[Xen-devel] [PATCH v8 04/13] arm/mem_access: Add short-descriptor pte typedefs and macros

The current implementation does not provide appropriate types for short-descriptor translation table entries. As such, this commit adds new types, which simplify managing the respective translation table entries. Signed-off-by: Sergej Proskurin Acked-by: Julien Grall

[Xen-devel] [PATCH v8 12/13] arm/mem_access: Add short-descriptor based gpt

This commit adds functionality to walk the guest's page tables using the short-descriptor translation table format for both ARMv7 and ARMv8. The implementation is based on ARM DDI 0487B-a J1-6002 and ARM DDI 0406C-b B3-1506. Signed-off-by: Sergej Proskurin Acked-by:

[Xen-devel] [PATCH v8 11/13] arm/mem_access: Add long-descriptor based gpt

This commit adds functionality to walk the guest's page tables using the long-descriptor translation table format for both ARMv7 and ARMv8. Similar to the hardware architecture, the implementation supports different page granularities (4K, 16K, and 64K). The implementation is based on ARM DDI

[Xen-devel] [PATCH v8 13/13] arm/mem_access: Walk the guest's pt in software

In this commit, we make use of the gpt walk functionality introduced in the previous commits. If mem_access is active, hardware-based gva to ipa translation might fail, as gva_to_ipa uses the guest's translation tables, access to which might be restricted by the active VTTBR. To side-step

[Xen-devel] [PATCH v8 05/13] arm/mem_access: Introduce GV2M_EXEC permission

We extend the current implementation by an additional permission, GV2M_EXEC, which will be used to describe execute permissions of PTE's as part of our guest translation table walk implementation. Signed-off-by: Sergej Proskurin Acked-by: Julien Grall

[Xen-devel] [PATCH v8 06/13] arm/mem_access: Introduce BIT_ULL bit operation

We introduce the BIT_ULL macro to using values of unsigned long long as to enable setting bits of 64-bit registers on AArch32. In addition, this commit adds a define holding the register width of 64 bit double-word registers. This define simplifies using the associated constants in the following

The current implementation of GENMASK is capable of creating bitmasks of 32-bit values on AArch32 and 64-bit values on AArch64. As we need to create masks for 64-bit values on AArch32 as well, in this commit we introduce the GENMASK_ULL bit operation. Please note that the GENMASK_ULL

The function p2m_mem_access_check_and_get_page in mem_access.c translates a gva to an ipa by means of the hardware functionality of the ARM architecture. This is implemented in the function gva_to_ipa. If mem_access is active, hardware-based gva to ipa translation might fail, as gva_to_ipa uses
