|

22 | * The VMM component is two things at the moment, it's a component doing a few
|
---|
23 | * management and routing tasks, and it's the whole virtual machine monitor
|
---|
24 | * thing. For hysterical reasons, it is not doing all the management that one
|
---|
25 | * would expect, this is instead done by @ref pg_vm. We'll address this

26 | * misdesign eventually, maybe.

74 | *
|

75 | * There are various resource limits imposed by the VMM and it's
|
---|
76 | * sub-components. We'll list some of them here.
|
---|
77 | *
|
---|
78 | * On 64-bit hosts:
|
---|
79 | * - Max 8191 VMs. Imposed by GVMM's handle allocation (GVMM_MAX_HANDLES),
|
---|
80 | * can be increased up to 64K - 1.
|
---|
81 | * - Max 16TB - 64KB of the host memory can be used for backing VM RAM and
|
---|
82 | * ROM pages. The limit is imposed by the 32-bit page ID used by GMM.
|
---|
83 | * - A VM can be assigned all the memory we can use (16TB), however, the
|
---|
84 | * Main API will restrict this to 2TB (MM_RAM_MAX_IN_MB).
|
---|
85 | * - Max 32 virtual CPUs (VMM_MAX_CPU_COUNT).
|
---|
86 | *
|
---|
87 | * On 32-bit hosts:
|
---|
88 | * - Max 127 VMs. Imposed by GMM's per page structure.
|
---|
89 | * - Max 64GB - 64KB of the host memory can be used for backing VM RAM and
|
---|
90 | * ROM pages. The limit is imposed by the 28-bit page ID used
|
---|
91 | * internally in GMM. It is also limited by PAE.
|
---|
92 | * - A VM can be assigned all the memory GMM can allocate, however, the
|
---|
93 | * Main API will restrict this to 3584MB (MM_RAM_MAX_IN_MB).
|
---|
94 | * - Max 32 virtual CPUs (VMM_MAX_CPU_COUNT).
