Subject: [PATCHv2 0/7] Add Intel Stratix10 FPGA manager and service layer
Date: Thu, 1 Mar 2018 18:19:28 -0600 [thread overview]
Message-ID: <1519949975-13548-1-git-send-email-richard.gong@linux.intel.com> (raw)
From: Richard Gong <richard.gong@intel.com>
This is the 2nd submission of Intel service layer patches. Intel Stratix10
FPGA manager, which is 1st service layer client, is included in this submission.
Service layer patches have been reviewed internally by Alan Tull and other
colleagues at Intel.
Intel Stratix10 SoC is composed of a 64 bit quad-core ARM Cortex A53 hard
processor system (HPS) and Secure Device Manager (SDM). SDM is the hardware
which does the FPGA configuration, QSPI, Crypto and warm reset.
When the FPGA is configured from HPS, there needs to be a way for HPS to
notify SDM the location and size of the configuration data. Then SDM will
get the configuration data from that location and perform the FPGA configuration.
To meet the whole system security needs and support virtual machine
requesting communication with SDM, only the secure world of software (EL3,
Exception Level 3) can interface with SDM. All software entities running
on other exception levels must channel through the EL3 software whenever it
needs service from SDM.
Intel Stratix10 service layer driver is added to provide the service for
FPGA configuration. Running at privileged exception level (EL1, Exception
Level 1), Intel Stratix10 service layer driver interfaces with the service
provider at EL1 (Intel Stratix10 FPGA Manager) and manages secure monitor
call (SMC) to communicate with secure monitor software at secure monitor
exception level (EL3).
Later the Intel Stratix10 service layer driver will be extended to provide
services for QSPI, Crypto and warm reset.
v2: add patches for FPGA manager, FPGA manager binding, dts and defconfig
remove intel-service subdirectory and intel-service.h, move intel-smc.h
and intel-service.c to driver/misc subdirectory
remove global variables
change service layer driver be 'default n'
correct SPDX markers
add timeout for do..while() loop
add kernel-doc for the functions and structs, correct multiline comments
replace kfifo_in/kfifo_out with kfifo_in_spinlocked/kfifo_out_spinlocked
rename struct intel_svc_data (at client header) to intel_svc_client_msg
rename struct intel_svc_private_mem to intel_svc_data
other corrections/changes from Intel internal code reviews
