of/fdt: Ignore disabled memory nodes

2022-05-17T18:06:32Z

When we boot a machine using a devicetree, the generic DT code goes through all nodes with a 'device_type = "memory"' property, and collects all memory banks mentioned there. However it does not check for the status property, so any nodes which are explicitly "disabled" will still be added as a memblock. This ends up badly for QEMU, when booting with secure firmware on arm/arm64 machines, because QEMU adds a node describing secure-only memory: =================== secram@e000000 { secure-status = "okay"; status = "disabled"; reg = <0x00 0xe000000 0x00 0x1000000>; device_type = "memory"; }; =================== The kernel will eventually use that memory block (which is located below the main DRAM bank), but accesses to that will be answered with an SError: =================== [ 0.000000] Internal error: synchronous external abort: 96000050 [#1] PREEMPT SMP [ 0.000000] Modules linked in: [ 0.000000] CPU: 0 PID: 0 Comm: swapper Not tainted 5.18.0-rc6-00014-g10c8acb8b679 #524 [ 0.000000] Hardware name: linux,dummy-virt (DT) [ 0.000000] pstate: 200000c5 (nzCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 0.000000] pc : new_slab+0x190/0x340 [ 0.000000] lr : new_slab+0x184/0x340 [ 0.000000] sp : ffff80000a4b3d10 .... ================== The actual crash location and call stack will be somewhat random, and depend on the specific allocation of that physical memory range. As the DT spec[1] explicitly mentions standard properties, add a simple check to skip over disabled memory nodes, so that we only use memory that is meant for non-secure code to use. That fixes booting a QEMU arm64 VM with EL3 enabled ("secure=on"), when not using UEFI. In this case the QEMU generated DT will be handed on to the kernel, which will see the secram node. This issue is reproducible when using TF-A together with U-Boot as firmware, then booting with the "booti" command. When using U-Boot as an UEFI provider, the code there [2] explicitly filters for disabled nodes when generating the UEFI memory map, so we are safe. EDK/2 only reads the first bank of the first DT memory node [3] to learn about memory, so we got lucky there.

of: Support more than one crash kernel regions for kexec -s

2022-05-07T18:57:35Z

When "crashkernel=X,high" is used, there may be two crash regions: high=crashk_res and low=crashk_low_res. But now the syscall kexec_file_load() only add crashk_res into "linux,usable-memory-range", this may cause the second kernel to have no available dma memory. Fix it like kexec-tools does for option -c, add both 'high' and 'low' regions into the dtb.

of: fdt: Add memory for devices by DT property "linux,usable-memory-range"

2022-05-07T18:54:33Z

When reserving crashkernel in high memory, some low memory is reserved for crash dump kernel devices and never mapped by the first kernel. This memory range is advertised to crash dump kernel via DT property under /chosen, linux,usable-memory-range = We reused the DT property linux,usable-memory-range and made the low memory region as the second range "BASE2 SIZE2", which keeps compatibility with existing user-space and older kdump kernels. Crash dump kernel reads this property at boot time and call memblock_add() to add the low memory region after memblock_cap_memory_range() has been called.
