Subject: 16KB PAGE_SIZE not work on DB410C
Date: Mon, 21 Dec 2015 12:00:28 +0800 [thread overview]
Message-ID: <5677795C.2060409@linaro.org> (raw)
Hello,
I want to do some tests over 16KB page size on dragonboard 410c. And I merged
arm64-upstream branch over
https://git.linaro.org/landing-teams/working/qualcomm/kernel.git integration-linux-qcomlt
which is based on Linux Kernel 4.3.
The db410c can boot into ubuntu in 4KB / 64KB page size, but when I set 16K page size, with
47bit VA, the kernel hang before kernel_start(), no log output.
Does db410c support 16K page size? What can I do to boot it up?
Below is what I got through serial port:
B - 437888 - QSEE Execution, Start
D - 61 - QSEE Execution, Delta
B - 443561 - SBL1, End
D - 245982 - SBL1, Delta
S - Flash Throughput, 111000 KB/s (1151760 Bytes, 10309 us)
S - DDR Frequency, 400 MHz
Android Bootloader - UART_DM Initialized!!!
