Details
QSEE is the Qualcomm Secure Execution Environment partition. It contains the first instance of the TrustZone OS.
The label of this partition is originally named 0:QSEE, which is an invalid article name in Mediawiki.
QSEE is stored in 2 instances and is loaded by the SBL and executed in the TrustZone environment.
The size and location differ each platform, see below.
The QSEE partitions are updated at boot time by tz_update and at update time by tzupdate.

Hawkeye
On Hawkeye both 4 MB sized QSEE partitons are located on the eMMC, the second instance is named QSEE_1.
See the SBL article for the partition table.
Dakota
On Dakota both *hidden* 512 KB sized QSEE partitons are located in mtd2, the second instance is named QSEE_B.
See the SBL article for the partition table.

Dependencies
Daily updated index of all dependencies of this partition. Last update: GMT.
A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.

Model-Matrix
Daily updated index of the presence, path and size of this partition for each model. Last update: 2024-04-25 06:31 GMT.
Showing all models using this partition. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.
