Hello everyone,
I hope you are having a wonderful weekend!!!
I'm porting AGL to bbai 32bits
I'm basing my porting in agl_bbe.inc, agl_beaglebone.inc and agl_j721e-evm.inc all of them are in meta-agl/meta-bsp/conf/include starting out previously from the templates at meta-agl/templates/machine/ for bbe and j721e-evm as suggested by Scott Murray in previous post I sent.
I have the following questions. If somebody can help, that would be much appreciated.
Ulises Vega
The following parameter appears in both agl_bbe.inc, and agl_beaglebone.inc
DISTRO_FEATURES:append = " agl-medium-arm-compiler"
Should I use it for my porting?
2.-
j721e-evm has a:
DEFAULTTUNE:k3r5 = "armv7athf"
1a) I want to find out the appropriate tuning for bbai32?
1b) should I use k3r5 or any other parameter? I know it has neon but I don't know which version?
I looked at this page https://en.wikipedia.org/wiki/Comparison_of_ARM_processors#ARMv7-A
and this one https://www.ti.com/lit/ds/symlink/am5729.pdf?ts=1682760256454
and https://git.yoctoproject.org/poky/plain/meta/conf/machine/include/arm/arch-armv7a.inc
but I don't know which tune to use.
3.-
In order to port AGL to bbai32 i want to know if the following layers are needed:
${METADIR}/bsp/meta-sancloud \
${METADIR}/bsp/meta-rtlwifi \
I got them from the template of meta-agl/templates/machine/bbe/50_bblayers.conf.inc
4.-
In order to port AGL to bbai32 I wan to enable graphics.
I saw two different configs for bbe PREFERRED_PROVIDER_virtual* are enabled but for bbe but not for beaglebone they are not .So what should I use for bbai32:
#-------------------------------------------------
## Graphics section ##
#-------------------------------------------------
PACKAGES_GFX = "ti-sgx-ddk-km"
IMAGE_INSTALL:append = " ${PACKAGES_GFX}"
# Enable Gfx Pkgs
MACHINE_FEATURES:append = " sgx"
MACHINE_FEATURES:append = " gpu"
BB_MULTI_PROVIDER_ALLOWED += "virtual/libgl virtual/egl virtual/libgles1 virtual/libgles2"
DEPENDS:remove = "virtual/libgl"
# Preferred providers
PREFERRED_PROVIDER_virtual/libgles1 = ""
PREFERRED_PROVIDER_virtual/libgles2 = "ti-sgx-ddk-um"
PREFERRED_PROVIDER_virtual/egl = "ti-sgx-ddk-um"
PREFERRED_PROVIDER_virtual/libgbm = "ti-sgx-ddk-um"
PREFERRED_PROVIDER_virtual/mesa = "mesa-gl"
