Author	SHA1	Message	Date
Palmer Dabbelt	21209988c7	Initialize the UART first Without this I can't get printf to show me debug info during early boot.	9 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
Andrew Waterman	220b1bee10	Fix(?) fcvt.s.w emulation for rs1 = -2^31 (#66)	9 years ago
Andrew Waterman	18087efa98	Make 4-byte aligned instruction-emulation loads atomic Per the Unix-class platform spec	9 years ago
Andrew Waterman	4c64de3213	Order __page_alloc before writing vmrs	9 years ago
Andrew Waterman	fb4e31229f	Stub out sys_prlimit64	9 years ago
Wesley W. Terpstra	3f20915eff	finisher: support terminating sifive devices simulation (#61)	9 years ago
Palmer Dabbelt	2dcae927fd	Merge pull request #60 from riscv/hart1 The DTB argument to boot_other_hart shouldn't be used in BBL	9 years ago
Palmer Dabbelt	147cfa612b	The DTB argument to boot_other_hart shouldn't be used in BBL I screwed up refactoring bbl.	9 years ago
Palmer Dabbelt	6b501de8e8	Merge pull request #59 from riscv/print-device-tree Add the '--enable-print-device-tree' argument	9 years ago
Palmer Dabbelt	ca24f3c904	Add the '--enable-print-device-tree' argument I'm trying to debug some device tree problems while booting Linux and figured it would be really nice to have access to the device tree while trying to debug these problems. I think this might be useful for lots of people, so I went ahead and cleaned up the code enough that it should actaully work in most cases.	9 years ago
Palmer Dabbelt	2187c4512d	Merge pull request #58 from riscv/platform Add a platform interface	9 years ago
Palmer Dabbelt	f0f85949a0	Allow platform__get_logo to return NULL	9 years ago
Palmer Dabbelt	0d202e9dd4	Add the '--with-platform' argument and the sifive-vc707-devkit platform Since we don't have a coherent platform specification right now, we've ended up with slightly different platforms between spike and our FPGA dev kit. For now I've added an autoconf option that allows users to select the relevant platform.	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
Palmer Dabbelt	62effc6bfe	Allow the platform to disable HTIF	9 years ago
Palmer Dabbelt	bb19fef663	Move the logo behind the platform interface SiFive has a different logo, so let platforms override said logo.	9 years ago
Palmer Dabbelt	9037b1d9f2	Add a platform interface SiFive's pk fork is the second one I've had to maintain, and it's a huge pain because people keep just leaving changes all over the tree. I want to introduce an interface that the platform-specific details can live behind so I don't have to keep doing these painful merges.	9 years ago
Palmer Dabbelt	8b80f2ea28	Ignore some generated files	9 years ago
Andrew Waterman	57bb80fb7d	Fix emulation of misaligned RVC loads/stores We were accidentally advancing the PC by 4, not 2.	9 years ago
Andrew Waterman	66701f82f8	FMV.X.S/FMV.S.X -> FMV.X.W/FMV.W.X	9 years ago
Andrew Waterman	3aebe0db7f	README.md: Explicitly list the requirement of a separate build directory. h/t Karsten Merker	9 years ago
Andrew Waterman	5ca090ba6c	Use uint64_t, not uintptr_t, to represent FDT addresses/sizes This fixes RV32 pk.	9 years ago
Andrew Waterman	770dcd9f1f	Fix RV32 compilation error	9 years ago
Andrew Waterman	0f0ac647fe	Increase PK stack size to 3% of memory, up to 8 MiB	9 years ago
Andrew Waterman	5f736b9ab8	Always write sbadaddr on trap redirection	9 years ago
Andrew Waterman	3a3c1f5a1a	Load instructions as unsigned values, not signed This matches the behavior of mbabaddr/mtval.	9 years ago
Wesley W. Terpstra	8197cad40c	mtrap: allow override of DISABLED_HART_MASK from CFLAGS	9 years ago
Andrew Waterman	a2c8937e63	Remove num_harts; use hart_mask exclusively	9 years ago
Andrew Waterman	dce2b7dd8e	Rename HART_MASK to DISABLED_HART_MASK to clarify polarity	9 years ago

Wesley W. Terpstra	cd558016be	fdt: support redaction	9 years ago
Andrew Waterman	d1200e3a54	Remove SBI console printm to speed up PK simulation	9 years ago
Wesley W. Terpstra	733fae9216	clint: move hart wakeup till after all FDT parsing The clint was wiping out information discovered by the plic. Initialize hart stacks as they are discovered. Then fill in clint+plic info Then wake the harts.	9 years ago
