Use the latter.\n\nThe _notdirty() variant is supposed to /not/ mark the updated\nCODE page as dirty, to not re-translate it. However this code\nis only used with the '-kernel' CLI option after the machine\nis created and /before/ the vCPUs run, and *only* during the\nfirst (cold) reset; not during following (hot) resets. The\noptimisation is totally not justified, since we haven't\ntranslated any guest code yet. Replace by the normal stl_phys()\nhelper.\n\nSuggested-by: Richard Henderson <richard.henderson@linaro.org>\nSigned-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>\n---\n hw/arm/aspeed.c | 3 +--\n hw/arm/boot.c | 6 ++----\n 2 files changed, 3 insertions(+), 6 deletions(-)", "diff": "diff --git a/hw/arm/aspeed.c b/hw/arm/aspeed.c\nindex 3a5071a3841..8ce82f1f622 100644\n--- a/hw/arm/aspeed.c\n+++ b/hw/arm/aspeed.c\n@@ -77,8 +77,7 @@ static void aspeed_reset_secondary(ARMCPU *cpu,\n CPUState *cs = CPU(cpu);\n \n /* info->smp_bootreg_addr */\n- address_space_stl_notdirty(as, AST_SMP_MBOX_FIELD_GOSIGN, 0,\n- MEMTXATTRS_UNSPECIFIED, NULL);\n+ stl_phys(as, AST_SMP_MBOX_FIELD_GOSIGN, 0);\n cpu_set_pc(cs, info->smp_loader_start);\n }\n \ndiff --git a/hw/arm/boot.c b/hw/arm/boot.c\nindex b91660208f5..5ca9c8db5cc 100644\n--- a/hw/arm/boot.c\n+++ b/hw/arm/boot.c\n@@ -266,8 +266,7 @@ static void default_reset_secondary(ARMCPU *cpu,\n AddressSpace *as = arm_boot_address_space(cpu, info);\n CPUState *cs = CPU(cpu);\n \n- address_space_stl_notdirty(as, info->smp_bootreg_addr,\n- 0, MEMTXATTRS_UNSPECIFIED, NULL);\n+ stl_phys(as, info->smp_bootreg_addr, 0);\n cpu_set_pc(cs, info->smp_loader_start);\n }\n \n@@ -277,8 +276,7 @@ static inline bool have_dtb(const struct arm_boot_info *info)\n }\n \n #define WRITE_WORD(p, value) do { \\\n- address_space_stl_notdirty(as, p, value, \\\n- MEMTXATTRS_UNSPECIFIED, NULL); \\\n+ stl_phys(as, p, value); \\\n p += 4; \\\n } while (0)\n \n", "prefixes": [ "03/14" ] }
