This requires an explanation: what does the number of CPU cores have to do with the memory attributes used for the framebuffer? > Signed-off-by: Marcin Juszkiewicz <marcin.juszkiew...@linaro.org> > --- > tests/avocado/machine_aarch64_sbsaref.py | 14 +++++++------- > 1 file changed, 7 insertions(+), 7 deletions(-) > > diff --git a/tests/avocado/machine_aarch64_sbsaref.py > b/tests/avocado/machine_aarch64_sbsaref.py > index 6bb82f2a03..e854ec6a1a 100644 > --- a/tests/avocado/machine_aarch64_sbsaref.py > +++ b/tests/avocado/machine_aarch64_sbsaref.py > @@ -37,18 +37,18 @@ def fetch_firmware(self): > > Used components: > > - - Trusted Firmware 2.11.0 > - - Tianocore EDK2 stable202405 > - - Tianocore EDK2-platforms commit 4bbd0ed > + - Trusted Firmware v2.11.0 > + - Tianocore EDK2 4d4f569924 > + - Tianocore EDK2-platforms 3f08401 > > """ > > # Secure BootRom (TF-A code) > fs0_xz_url = ( > > "https://artifacts.codelinaro.org/artifactory/linaro-419-sbsa-ref/"; > - "20240528-140808/edk2/SBSA_FLASH0.fd.xz" > + "20240619-148232/edk2/SBSA_FLASH0.fd.xz" > ) > - fs0_xz_hash = > "fa6004900b67172914c908b78557fec4d36a5f784f4c3dd08f49adb75e1892a9" > + fs0_xz_hash = > "0c954842a590988f526984de22e21ae0ab9cb351a0c99a8a58e928f0c7359cf7" > tar_xz_path = self.fetch_asset(fs0_xz_url, asset_hash=fs0_xz_hash, > algorithm='sha256') > archive.extract(tar_xz_path, self.workdir) > @@ -57,9 +57,9 @@ def fetch_firmware(self): > # Non-secure rom (UEFI and EFI variables) > fs1_xz_url = ( > > "https://artifacts.codelinaro.org/artifactory/linaro-419-sbsa-ref/"; > - "20240528-140808/edk2/SBSA_FLASH1.fd.xz" > + "20240619-148232/edk2/SBSA_FLASH1.fd.xz" > ) > - fs1_xz_hash = > "5f3747d4000bc416d9641e33ff4ac60c3cc8cb74ca51b6e932e58531c62eb6f7" > + fs1_xz_hash = > "c6ec39374c4d79bb9e9cdeeb6db44732d90bb4a334cec92002b3f4b9cac4b5ee" > tar_xz_path = self.fetch_asset(fs1_xz_url, asset_hash=fs1_xz_hash, > algorithm='sha256') > archive.extract(tar_xz_path, self.workdir) > > -- > 2.45.1 >
