Some 3rd party Linux distributions, set the kernel configuration option "CONFIG_FRAME_WARN=1024" which will causes the compiler to generate compilation errors when a functions stack frame size exceeds 1024 bytes. When compiling the DLA driver on Fedora the compilation fails with the following errors. drivers/video/tegra/host/nvdla/nvdla.o] Error 1 drivers/video/tegra/host/nvdla/nvdla_ioctl.c: In function ‘nvdla_emu_task_submit’: build/drivers/video/tegra/host/nvdla/nvdla_ioctl.c:918:1: error: the frame size of 1456 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] drivers/video/tegra/host/nvdla/nvdla_ioctl.c: In function ‘nvdla_submit’: drivers/video/tegra/host/nvdla/nvdla_ioctl.c:1118:1: error: the frame size of 1440 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Fix this by copying the user tasks from userspace one at a time and allocating the structure nvdla_emu_task dynamically so that is it not allocated on the stack.
