From 4860af2c4fc4632c180ba902758f6a7f66ed9ac1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Thu, 13 Jun 2024 12:30:00 +0200 Subject: [PATCH] target/s390x: Use s390_skeys_get|set() helper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit c9274b6bf0 ("target/s390x: start moving TCG-only code to tcg/") moved mem_helper.c, but the trace-events file is still in the parent directory, so is the generated trace.h. Call the s390_skeys_get|set() helper, removing the need for the trace event shared with the tcg/ sub-directory, fixing the following build failure: In file included from ../target/s390x/tcg/mem_helper.c:33: ../target/s390x/tcg/trace.h:1:10: fatal error: 'trace/trace-target_s390x_tcg.h' file not found #include "trace/trace-target_s390x_tcg.h" Reported-by: Mark Cave-Ayland Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Thomas Huth Reviewed-by: Paolo Bonzini Message-Id: <20240613104415.9643-3-philmd@linaro.org> --- target/s390x/mmu_helper.c | 11 ++--------- target/s390x/tcg/mem_helper.c | 16 ++++------------ target/s390x/trace-events | 4 ---- 3 files changed, 6 insertions(+), 25 deletions(-) diff --git a/target/s390x/mmu_helper.c b/target/s390x/mmu_helper.c index f3a2f25a5c..6c59d0d216 100644 --- a/target/s390x/mmu_helper.c +++ b/target/s390x/mmu_helper.c @@ -25,7 +25,6 @@ #include "sysemu/tcg.h" #include "exec/exec-all.h" #include "exec/page-protection.h" -#include "trace.h" #include "hw/hw.h" #include "hw/s390x/storage-keys.h" #include "hw/boards.h" @@ -303,7 +302,6 @@ static void mmu_handle_skey(target_ulong addr, int rw, int *flags) static S390SKeysClass *skeyclass; static S390SKeysState *ss; uint8_t key, old_key; - int rc; /* * We expect to be called with an absolute address that has already been @@ -341,9 +339,7 @@ static void mmu_handle_skey(target_ulong addr, int rw, int *flags) * * TODO: we have races between getting and setting the key. */ - rc = skeyclass->get_skeys(ss, addr / TARGET_PAGE_SIZE, 1, &key); - if (rc) { - trace_get_skeys_nonzero(rc); + if (s390_skeys_get(ss, addr / TARGET_PAGE_SIZE, 1, &key)) { return; } old_key = key; @@ -371,10 +367,7 @@ static void mmu_handle_skey(target_ulong addr, int rw, int *flags) key |= SK_R; if (key != old_key) { - rc = skeyclass->set_skeys(ss, addr / TARGET_PAGE_SIZE, 1, &key); - if (rc) { - trace_set_skeys_nonzero(rc); - } + s390_skeys_set(ss, addr / TARGET_PAGE_SIZE, 1, &key); } } diff --git a/target/s390x/tcg/mem_helper.c b/target/s390x/tcg/mem_helper.c index 6a308c5553..6cdbc34178 100644 --- a/target/s390x/tcg/mem_helper.c +++ b/target/s390x/tcg/mem_helper.c @@ -30,7 +30,6 @@ #include "hw/core/tcg-cpu-ops.h" #include "qemu/int128.h" #include "qemu/atomic128.h" -#include "trace.h" #if !defined(CONFIG_USER_ONLY) #include "hw/s390x/storage-keys.h" @@ -2093,9 +2092,8 @@ uint64_t HELPER(iske)(CPUS390XState *env, uint64_t r2) } } - rc = skeyclass->get_skeys(ss, addr / TARGET_PAGE_SIZE, 1, &key); + rc = s390_skeys_get(ss, addr / TARGET_PAGE_SIZE, 1, &key); if (rc) { - trace_get_skeys_nonzero(rc); return 0; } return key; @@ -2108,7 +2106,6 @@ void HELPER(sske)(CPUS390XState *env, uint64_t r1, uint64_t r2) static S390SKeysClass *skeyclass; uint64_t addr = wrap_address(env, r2); uint8_t key; - int rc; addr = mmu_real2abs(env, addr); if (!mmu_absolute_addr_valid(addr, false)) { @@ -2124,10 +2121,7 @@ void HELPER(sske)(CPUS390XState *env, uint64_t r1, uint64_t r2) } key = r1 & 0xfe; - rc = skeyclass->set_skeys(ss, addr / TARGET_PAGE_SIZE, 1, &key); - if (rc) { - trace_set_skeys_nonzero(rc); - } + s390_skeys_set(ss, addr / TARGET_PAGE_SIZE, 1, &key); /* * As we can only flush by virtual address and not all the entries * that point to a physical address we have to flush the whole TLB. @@ -2157,18 +2151,16 @@ uint32_t HELPER(rrbe)(CPUS390XState *env, uint64_t r2) } } - rc = skeyclass->get_skeys(ss, addr / TARGET_PAGE_SIZE, 1, &key); + rc = s390_skeys_get(ss, addr / TARGET_PAGE_SIZE, 1, &key); if (rc) { - trace_get_skeys_nonzero(rc); return 0; } re = key & (SK_R | SK_C); key &= ~SK_R; - rc = skeyclass->set_skeys(ss, addr / TARGET_PAGE_SIZE, 1, &key); + rc = s390_skeys_set(ss, addr / TARGET_PAGE_SIZE, 1, &key); if (rc) { - trace_set_skeys_nonzero(rc); return 0; } /* diff --git a/target/s390x/trace-events b/target/s390x/trace-events index 729cb012b4..d371ef71b9 100644 --- a/target/s390x/trace-events +++ b/target/s390x/trace-events @@ -1,9 +1,5 @@ # See docs/devel/tracing.rst for syntax documentation. -# mmu_helper.c -get_skeys_nonzero(int rc) "SKEY: Call to get_skeys unexpectedly returned %d" -set_skeys_nonzero(int rc) "SKEY: Call to set_skeys unexpectedly returned %d" - # ioinst.c ioinst(const char *insn) "IOINST: %s" ioinst_sch_id(const char *insn, int cssid, int ssid, int schid) "IOINST: %s (%x.%x.%04x)"
