Unfortunately this design is fatally flawed, because it means that there is a lag between the ptimer updating its own state and the device callback function updating device state, and guest accesses to device registers between the two can return inconsistent device state. We want to replace the bottom-half design with one where the guest device's callback is called either immediately (when the ptimer triggers by timeout) or when the device model code closes a transaction-begin/end section (when the ptimer triggers because the device model changed the ptimer's count value or other state). As the first step, rename ptimer_init() to ptimer_init_with_bh(), to free up the ptimer_init() name for the new API. We can then convert all the ptimer users away from ptimer_init_with_bh() before removing it entirely. (Commit created with git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/' and three overlong lines folded by hand.)

-- 2.20.1 Provide the new transaction-based API. If a ptimer is created using ptimer_init() rather than ptimer_init_with_bh(), then instead of providing a QEMUBH, it provides a pointer to the callback function directly, and has opted into the transaction API. All calls to functions which modify ptimer state: - ptimer_set_period() - ptimer_set_freq() - ptimer_set_limit() - ptimer_set_count() - ptimer_run() - ptimer_stop() must be between matched calls to ptimer_transaction_begin() and ptimer_transaction_commit(). When ptimer_transaction_commit() is called it will evaluate the state of the timer after all the changes in the transaction, and call the callback if necessary. In the old API the individual update functions generally would call ptimer_trigger() immediately, which would schedule the QEMUBH. In the new API the update functions will instead defer the "set s->next_event and call ptimer_reload()" work to ptimer_transaction_commit(). Because ptimer_trigger() can now immediately call into the device code which may then call other ptimer functions that update ptimer_state fields, we must be more careful in ptimer_reload() not to cache fields from ptimer_state across the ptimer_trigger() call. (This was harmless with the QEMUBH mechanism as the BH would not be invoked until much later.) We use assertions to check that: * the functions modifying ptimer state are not called outside a transaction block * ptimer_transaction_begin() and _commit() calls are paired * the transaction API is not used with a QEMUBH ptimer There is some slight repetition of code: * most of the set functions have similar looking "if s->bh call ptimer_reload, otherwise set s->need_reload" code * ptimer_init() and ptimer_init_with_bh() have similar code We deliberately don't try to avoid this repetition, because it will all be deleted when the QEMUBH version of the API is removed.

Part of the semihosting 2.0 specification requires that we implement special handling of opening a ":semihosting-features" filename. Guest fds which result from opening the special file won't correspond to host fds, so to ensure that we don't end up with duplicate fds we need to have QEMU code control the allocation of the fd values we give the guest. Add in an abstraction layer which lets us allocate new guest FD values, and translate from a guest FD value back to the host one. This also fixes an odd hole where a semihosting guest could use the semihosting API to read, write or close file descriptors that it had never allocated but which were being used by QEMU itself. (This isn't a security hole, because enabling semihosting permits the guest to do arbitrary file access to the whole host filesystem, and so should only be done if the guest is completely trusted.) Currently the only kind of guest fd is one which maps to a host fd, but in a following commit we will add one which maps to the :semihosting-features magic data. If the guest is migrated with an open semihosting file descriptor then subsequent attempts to use the fd will all fail; this is not a change from the previous situation (where the host fd being used on the source end would not be re-opened on the destination end).

We want to add a third one to deal with the magic :semihosting-features file. Instead of having a three-way if statement in each of these cases, factor out the implementation of the calls to separate functions which we dispatch to via function pointers selected via the GuestFDType for the guest fd.

This works by the guest opening a magic file ":semihosting-features", which contains a fixed set of data with some magic numbers followed by a sequence of bytes with feature flags. The file is expected to behave sensibly for the various semihosting calls which operate on files (SYS_FLEN, SYS_SEEK, etc). Implement this as another kind of guest FD using our function table dispatch mechanism. Initially we report no extended features, so we have just one feature flag byte which is zero.

The Cortex CPU and its interrupt controller are too complex to handle in the common Aspeed SoC framework. We introduce a new Aspeed SoC class with instance_init and realize handlers to handle the differences with the AST2400 and the AST2500 SoCs. This will add extra work to keep in sync both models with future extensions but it makes the code clearer.

As most of the checks aren't possible without a valid dte split that check apart and then check the other conditions in steps. This avoids us relying on undefined data. I still get a failure with the current kvm-unit-tests but at least I know (partially) why now: Exception return from AArch64 EL1 to AArch64 EL1 PC 0x40080588 PASS: gicv3: its-trigger: inv/invall: dev2/eventid=20 now triggers an LPI ITS: MAPD devid=2 size = 0x8 itt=0x40430000 valid=0 INT dev_id=2 event_id=20 process_its_cmd: invalid command attributes: invalid dte: 0 for 2 (MEM_TX: 0) PASS: gicv3: its-trigger: mapd valid=false: no LPI after device unmap SUMMARY: 6 tests, 1 unexpected failures Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 20211112170454.3158925-1-alex.bennee@linaro.org Cc: Shashi Mallela <shashi.mallela@linaro.org> Cc: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> --- hw/intc/arm_gicv3_its.c | 39 +++++++++++++++++++++++++++------------ 1 file changed, 27 insertions(+), 12 deletions(-) diff --git a/hw/intc/arm_gicv3_its.c b/hw/intc/arm_gicv3_its.c index XXXXXXX..XXXXXXX 100644 --- a/hw/intc/arm_gicv3_its.c +++ b/hw/intc/arm_gicv3_its.c @@ -XXX,XX +XXX,XX @@ static bool process_its_cmd(GICv3ITSState *s, uint64_t value, uint32_t offset, if (res != MEMTX_OK) { return result; } + } else { + qemu_log_mask(LOG_GUEST_ERROR, + "%s: invalid command attributes: " + "invalid dte: %"PRIx64" for %d (MEM_TX: %d)\n", + __func__, dte, devid, res); + return result; } - if ((devid > s->dt.maxids.max_devids) || !dte_valid || !ite_valid || - !cte_valid || (eventid > max_eventid)) { + + /* + * In this implementation, in case of guest errors we ignore the + * command and move onto the next command in the queue. + */ + if (devid > s->dt.maxids.max_devids) { qemu_log_mask(LOG_GUEST_ERROR, - "%s: invalid command attributes " - "devid %d or eventid %d or invalid dte %d or" - "invalid cte %d or invalid ite %d\n", - __func__, devid, eventid, dte_valid, cte_valid, - ite_valid); - /* - * in this implementation, in case of error - * we ignore this command and move onto the next - * command in the queue - */ + "%s: invalid command attributes: devid %d>%d", + __func__, devid, s->dt.maxids.max_devids); + + } else if (!dte_valid || !ite_valid || !cte_valid) { + qemu_log_mask(LOG_GUEST_ERROR, + "%s: invalid command attributes: " + "dte: %s, ite: %s, cte: %s\n", + __func__, + dte_valid ?

Prior to v8, this case is UNDEFINED. With v8, this is CONSTRAINED UNPREDICTABLE and may either raise an exception or force align the PC.
