Hi,
I spent some time with the fTPM module and TA on a Nitrogen6X with the
latest OP-TEE master. After stumbling through the "tee_supplicant no
persistent storage" problem, my module now issues the following error
message on module load:
[ 34.633252] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMA
Hi,
Thanks for the feedback so far. This is an updated series documenting
the AArch64 Tagged Address ABI as implemented by these patches:

Idle page tracking currently does not work well in the following
scenario:
1. mark page-A idle which was present at that time.
2. run workload
3. page-A is not touched by workload
4. *sudden* memory pressure happen so finally page A is finally swapped out
5. now see the page A - it appears as
During idle page tracking, we see that sometimes faulted anon pages are in
pagevec but are not drained to LRU. Idle page tracking only considers pages
on LRU.
I am able to find multiple issues involving this. One issue looks like
idle tracking is completely broken. It shows up in my testing as if
The page_idle tracking feature currently requires looking up the pagemap
for a process followed by interacting with /sys/kernel/mm/page_idle.
Looking up PFN from pagemap in Android devices is not supported by
unprivileged process and requires SYS_ADMIN and gives 0 for the PFN.
This patch adds supp

This patch updates the documentation with the new page_idle tracking
feature which uses virtual address indexing.
