- Assume that CPU manufacturer (e.g., Intel or AMD for RDSEED or
- RDRAND, IBM for the S390 and Power PC architectures) is trustworthy
- for the purposes of initializing Linux's CRNG. Since this is not
- something that can be independently audited, this amounts to trusting
- that CPU manufacturer (perhaps with the insistence or mandate
- of a Nation State's intelligence or law enforcement agencies)
- has not installed a hidden back door to compromise the CPU's
- random number generation facilities. This can also be configured
- at boot with "random.trust_cpu=on/off".
+ Initialize the RNG using random numbers supplied by the CPU's
+ RNG instructions (e.g. RDRAND), if supported and available. These
+ random numbers are never used directly, but are rather hashed into
+ the main input pool, and this happens regardless of whether or not
+ this option is enabled. Instead, this option controls whether the
+ they are credited and hence can initialize the RNG. Additionally,
+ other sources of randomness are always used, regardless of this
+ setting. Enabling this implies trusting that the CPU can supply high
+ quality and non-backdoored random numbers.
+

- Some bootloaders can provide entropy to increase the kernel's initial

- only mixes the entropy pool. This can also be configured at boot with

+ * Handling of free grants:
+ *
+ * Free grants are in a simple list anchored in gnttab_free_head. They are
+ * linked by grant ref, the last element contains GNTTAB_LIST_END. The number
+ * of free entries is stored in gnttab_free_count.
+ * Additionally there is a bitmap of free entries anchored in
+ * gnttab_free_bitmap. This is being used for simplifying allocation of
+ * multiple consecutive grants, which is needed e.g. for support of virtio.
+ * gnttab_last_free is used to add free entries of new frames at the end of
+ * the free list.
+ * gnttab_free_tail_ptr specifies the variable which references the start
+ * of consecutive free grants ending with gnttab_last_free. This pointer is
+ * updated in a rather defensive way, in order to avoid performance hits in
+ * hot paths.
+ * All those variables are protected by gnttab_list_lock.
