7 menu "Qualcomm firmware drivers"
12 config QCOM_SCM_DOWNLOAD_MODE_DEFAULT
13 bool "Qualcomm download mode enabled by default"
16 A device with "download mode" enabled will upon an unexpected
17 warm-restart enter a special debug mode that allows the user to
18 "download" memory content over USB for offline postmortem analysis.
19 The feature can be enabled/disabled on the kernel command line.
21 Say Y here to enable "download mode" by default.
24 bool "Qualcomm QSEECOM interface driver"
28 Various Qualcomm SoCs have a Secure Execution Environment (SEE) running
29 in the Trust Zone. This module provides an interface to that via the
30 QSEECOM mechanism, using SCM calls.
32 The QSEECOM interface allows, among other things, access to applications
33 running in the SEE. An example of such an application is 'uefisecapp',
34 which is required to access UEFI variables on certain systems. If
35 selected, the interface will also attempt to detect and register client
36 devices for supported applications.
38 Select Y here to enable the QSEECOM interface driver.
40 config QCOM_QSEECOM_UEFISECAPP
41 bool "Qualcomm SEE UEFI Secure App client driver"
42 depends on QCOM_QSEECOM
45 Various Qualcomm SoCs do not allow direct access to EFI variables.
46 Instead, these need to be accessed via the UEFI Secure Application
47 (uefisecapp), residing in the Secure Execution Environment (SEE).
49 This module provides a client driver for uefisecapp, installing efivar
50 operations to allow the kernel accessing EFI variables, and via that also
51 provide user-space with access to EFI variables via efivarfs.
53 Select Y here to provide access to EFI variables on the aforementioned
