From 7f4fbfb5dc08fe3fb6829bde8e4072d6cb214931 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 23 Sep 2022 13:34:10 +0100 Subject: target/arm: Mark registers which call pmu_op_start() as ARM_CP_IO In commit 01765386a888 we made some system register write functions call pmu_op_start()/pmu_op_finish(). This means that they now touch timers, so for icount to work these registers must have the ARM_CP_IO flag set. This fixes a bug where when icount is enabled a guest that touches MDCR_EL3, MDCR_EL2, PMCNTENSET_EL0 or PMCNTENCLR_EL0 would cause QEMU to print an error message and exit, for example: [ 2.495971] TCP: Hash tables configured (established 1024 bind 1024) [ 2.496213] UDP hash table entries: 256 (order: 1, 8192 bytes) [ 2.496386] UDP-Lite hash table entries: 256 (order: 1, 8192 bytes) [ 2.496917] NET: Registered protocol family 1 qemu-system-aarch64: Bad icount read Reported-by: Thomas Huth Signed-off-by: Peter Maydell Reviewed-by: Richard Henderson Message-id: 20220923123412.1214041-2-peter.maydell@linaro.org --- target/arm/helper.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/target/arm/helper.c b/target/arm/helper.c index b5dac65..fadeed0 100644 --- a/target/arm/helper.c +++ b/target/arm/helper.c @@ -1927,12 +1927,12 @@ static const ARMCPRegInfo v7_cp_reginfo[] = { * or PL0_RO as appropriate and then check PMUSERENR in the helper fn. */ { .name = "PMCNTENSET", .cp = 15, .crn = 9, .crm = 12, .opc1 = 0, .opc2 = 1, - .access = PL0_RW, .type = ARM_CP_ALIAS, + .access = PL0_RW, .type = ARM_CP_ALIAS | ARM_CP_IO, .fieldoffset = offsetoflow32(CPUARMState, cp15.c9_pmcnten), .writefn = pmcntenset_write, .accessfn = pmreg_access, .raw_writefn = raw_write }, - { .name = "PMCNTENSET_EL0", .state = ARM_CP_STATE_AA64, + { .name = "PMCNTENSET_EL0", .state = ARM_CP_STATE_AA64, .type = ARM_CP_IO, .opc0 = 3, .opc1 = 3, .crn = 9, .crm = 12, .opc2 = 1, .access = PL0_RW, .accessfn = pmreg_access, .fieldoffset = offsetof(CPUARMState, cp15.c9_pmcnten), .resetvalue = 0, @@ -1942,11 +1942,11 @@ static const ARMCPRegInfo v7_cp_reginfo[] = { .fieldoffset = offsetoflow32(CPUARMState, cp15.c9_pmcnten), .accessfn = pmreg_access, .writefn = pmcntenclr_write, - .type = ARM_CP_ALIAS }, + .type = ARM_CP_ALIAS | ARM_CP_IO }, { .name = "PMCNTENCLR_EL0", .state = ARM_CP_STATE_AA64, .opc0 = 3, .opc1 = 3, .crn = 9, .crm = 12, .opc2 = 2, .access = PL0_RW, .accessfn = pmreg_access, - .type = ARM_CP_ALIAS, + .type = ARM_CP_ALIAS | ARM_CP_IO, .fieldoffset = offsetof(CPUARMState, cp15.c9_pmcnten), .writefn = pmcntenclr_write }, { .name = "PMOVSR", .cp = 15, .crn = 9, .crm = 12, .opc1 = 0, .opc2 = 3, @@ -5125,7 +5125,7 @@ static const ARMCPRegInfo v8_cp_reginfo[] = { .opc0 = 3, .opc1 = 6, .crn = 1, .crm = 3, .opc2 = 1, .resetvalue = 0, .access = PL3_RW, .fieldoffset = offsetof(CPUARMState, cp15.mdcr_el3) }, - { .name = "SDCR", .type = ARM_CP_ALIAS, + { .name = "SDCR", .type = ARM_CP_ALIAS | ARM_CP_IO, .cp = 15, .opc1 = 0, .crn = 1, .crm = 3, .opc2 = 1, .access = PL1_RW, .accessfn = access_trap_aa32s_el1, .writefn = sdcr_write, @@ -7832,7 +7832,7 @@ void register_cp_regs_for_features(ARMCPU *cpu) * value is MDCR_EL2.HPMN which should reset to the value of PMCR_EL0.N. */ ARMCPRegInfo mdcr_el2 = { - .name = "MDCR_EL2", .state = ARM_CP_STATE_BOTH, + .name = "MDCR_EL2", .state = ARM_CP_STATE_BOTH, .type = ARM_CP_IO, .opc0 = 3, .opc1 = 4, .crn = 1, .crm = 1, .opc2 = 1, .writefn = mdcr_el2_write, .access = PL2_RW, .resetvalue = pmu_num_counters(env), -- cgit v1.1 From 80d2b43b2ff367f38ae4c9616b1ed261ecf801b6 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 23 Sep 2022 13:34:11 +0100 Subject: target/arm: Make writes to MDCR_EL3 use PMU start/finish calls In commit 01765386a88868 we fixed a bug where we weren't correctly bracketing changes to some registers with pmu_op_start() and pmu_op_finish() calls for changes which affect whether the PMU counters might be enabled. However, we missed the case of writes to the AArch64 MDCR_EL3 register, because (unlike its AArch32 counterpart) they are currently done directly to the CPU state struct without going through the sdcr_write() function. Give MDCR_EL3 a writefn which handles the PMU start/finish calls. The SDCR writefn then simplfies to "call the MDCR_EL3 writefn after masking off the bits which don't exist in the AArch32 register".

In particular in commit 0b42f4fab9d3 we forgot to add SCCD, which meant that an AArch32 guest couldn't actually use the SCCD bit to disable counting in Secure state. Add all the currently defined bits; we don't implement all of them, but this makes them be reads-as-written, which is architecturally valid and matches how we currently handle most of the others in the mask.

The specification recommends that 'compatible' follows the format 'manufacturer,model' and 'model' follows the format 'manufacturer,model-number'. Since our 'compatible' doesn't observe this, 'model' doesn't really need to either.

In QEMU, MSI transactions contain the requester ID, so the PCI node should use the "msi-map" property instead of "msi-parent". In our case the property describes an identity map between requester ID and sideband data.
