Author	SHA1	Message	Date
Yan	a4d4298ca1	Disable device tree filter when load a dts from file (#219) * add device tree in elf, using --with-dts to add the absolute path of device tree * Disable device tree filter * Remove *.dtb dependence, when the --with-dts option is not used	5 years ago
Andrew Waterman	def2f01eee	Revert "Disable device tree filter when load a dts from file (#217)" This reverts commit a161e6f3ef. Resolves #218	5 years ago

James Clarke	2c4e689bc1	Support manually zeroing out BSS when booting (#188) Some ELF loaders, in particular gdb's load command for dynamically loading files into memory, which is often used to load binaries onto FPGAs over JTAG, do not zero out BSS, leaving the memory in whatever state it was previously in. Thus, introduce a new --enable-zero-bss configure flag, which will include code to zero out BSS when booting.	6 years ago

Wesley W. Terpstra	2bbd8e1a1b	mtrap: add a halt IPI used for poweroff (#86) Otherwise, linux complains the moment an interrupt arrives and wakes up one of the not-looping cores.	8 years ago
Palmer Dabbelt	21dbf5f307	Boot on the first hart This code is broken, and it's left over from before we could read the DTB to find harts to boot on.	8 years ago
Palmer Dabbelt	9204785053	Detect harts that can't boot Linux instead of hard-coding them This checks to see if a hart can't boot Linux by looking for a compatible "mmu-type" field. If the hart can't boot Linux, then bbl masks it off.	9 years ago
Palmer Dabbelt	298984cbe6	Move DISABLED_HART_MASK to the platform Some platforms can't boot Linux on all the harts. This commit allows platforms to define the set of harts that should be prevented from booting past BBL. This is essentially just a new mechanism for defining the DISABLED_HART_MASK.	9 years ago

sashimi-yzh	f892b43a2b	machine, mentry.S: fix not receiving IPI for other harts (#38) * Before waiting for IPI by executing wfi instruction, MSIE bit should be set in mie CSR for other harts, else they will get stuck at the wfi instruction.	10 years ago
