Hi, this is a follow up of a recent discussion: Let's convert the pio_bitmap to a pio_whitelist.
It supports readability (no more bit fiddling), writeability (no more bit fiddling), reduces the size of cell configs (per-config reduction of almost 8kiB), and generally, it's more Jailhouse-like than the blacklist-like former pio_bitmap. This series first cleans up and consolidates a few spots, and then switches to the whitelist. Logically the series is pretty straight forward, still, there's one little trade-off: vcpu_cell_exit. We have some more complexity there. But hey, look at the diffstat! Ralf since v2: - Remove .pio_bitmap from ARM64 configs - s/pio_bitmap_size/num_pio_regions/ in jailhouse-cell-linux since v1: - rebase on upstream next, respect integrated changes - refactor jailhouse_pio_whitelist to jailhouse_pio - more consolidation! Ralf Ramsauer (5): configs: arm64: don't set .pio_bitmap_size x86: drop vcpu_vendor_get_cell_io_bitmap and struct vcpu_io_bitmap cell-config: introduce pio_whitelist structure and helpers x86: pio: use a whitelist instead of a permission bitmap tools: update config generator configs/arm64/amd-seattle-gic-demo.c | 1 - configs/arm64/amd-seattle-uart-demo.c | 1 - configs/arm64/espressobin-gic-demo.c | 1 - configs/arm64/foundation-v8-gic-demo.c | 1 - configs/arm64/foundation-v8-linux-demo.c | 1 - configs/arm64/foundation-v8-uart-demo.c | 1 - configs/arm64/hikey-gic-demo.c | 1 - configs/arm64/imx8mq-gic-demo.c | 1 - configs/arm64/k3-am654-gic-demo.c | 1 - configs/arm64/k3-am654-uart-demo.c | 1 - configs/arm64/macchiatobin-gic-demo.c | 1 - configs/arm64/miriac-sbc-ls1046a-gic-demo.c | 1 - configs/arm64/qemu-arm64-gic-demo.c | 1 - configs/arm64/ultra96-gic-demo.c | 1 - configs/arm64/zynqmp-zcu102-gic-demo.c | 1 - configs/x86/apic-demo.c | 16 ++-- configs/x86/e1000-demo.c | 19 ++-- configs/x86/f2a88xm-hd3.c | 27 +++--- configs/x86/imb-a180.c | 27 +++--- configs/x86/ioapic-demo.c | 22 ++--- configs/x86/ivshmem-demo.c | 13 +-- configs/x86/linux-x86-demo.c | 16 ++-- configs/x86/pci-demo.c | 16 ++-- configs/x86/qemu-x86.c | 41 +++----- configs/x86/smp-demo.c | 16 ++-- configs/x86/tiny-demo.c | 16 ++-- hypervisor/arch/x86/include/asm/vcpu.h | 7 -- hypervisor/arch/x86/svm.c | 7 -- hypervisor/arch/x86/vcpu.c | 100 +++++++++++--------- hypervisor/arch/x86/vmx.c | 7 -- include/jailhouse/cell-config.h | 28 ++++-- tools/jailhouse-cell-linux | 4 +- tools/jailhouse-hardware-check | 2 +- tools/root-cell-config.c.tmpl | 22 ++--- 34 files changed, 175 insertions(+), 246 deletions(-) -- 2.22.0 -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
