2015-04-26Switch non-CPU callers from ld/st*_phys to address_space_ld/st*Peter Maydell
Switch all the uses of ld/st*_phys to address_space_ld/st*, except for those cases where the address space is the CPU's (ie cs->as). This was done with the following script which generates a Coccinelle patch. A few over-80-columns lines in the result were rewrapped by hand where Coccinelle failed to do the wrapping automatically, as well as one location where it didn't put a line-continuation '\' when wrapping lines on a change made to a match inside a macro definition. ===begin=== #!/bin/sh -e # Usage: # ./ldst-phys.spatch.sh > ldst-phys.spatch # spatch -sp_file ldst-phys.spatch -dir . | sed -e '/^+/s/\t/ /g' > out.patch # patch -p1 < out.patch for FN in ub uw_le uw_be l_le l_be q_le q_be uw l q; do cat <<EOF @ cpu_matches_ld_${FN} @ expression E1,E2; identifier as; @@ ld${FN}_phys(E1->as,E2) @ other_matches_ld_${FN} depends on !cpu_matches_ld_${FN} @ expression E1,E2; @@ -ld${FN}_phys(E1,E2) +address_space_ld${FN}(E1,E2, MEMTXATTRS_UNSPECIFIED, NULL) EOF done for FN in b w_le w_be l_le l_be q_le q_be w l q; do cat <<EOF @ cpu_matches_st_${FN} @ expression E1,E2,E3; identifier as; @@ st${FN}_phys(E1->as,E2,E3) @ other_matches_st_${FN} depends on !cpu_matches_st_${FN} @ expression E1,E2,E3; @@ -st${FN}_phys(E1,E2,E3) +address_space_st${FN}(E1,E2,E3, MEMTXATTRS_UNSPECIFIED, NULL) EOF done ===endit=== Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Edgar E.

2015-03-09Generalize QOM publishing of date and time from mc146818rtc.cDavid Gibson
The mc146818rtc driver exposes the current RTC date and time via the "date" property in QOM (which is also aliased to the machine's "rtc-time" property). Currently it uses a custom visitor function rtc_get_date to do this. This patch introduces new helpers to the QOM core to expose struct tm valued properties via a getter function, so that this functionality can be more easily duplicated in other RTC implementations.

2014-05-15qapi: Replace uncommon use of the error API by the common oneMarkus Armbruster
We commonly use the error API like this: err = NULL; foo(..., &err); if (err) { goto out; } bar(..., &err); Every error source is checked separately. The second function is only called when the first one succeeds. Both functions are free to pass their argument to error_set(). Because error_set() asserts no error has been set, this effectively means they must not be called with an error set. The qapi-generated code uses the error API differently: // *errp was initialized to NULL somewhere up the call chain frob(..., errp); gnat(..., errp); Errors accumulate in *errp: first error wins, subsequent errors get dropped. To make this work, the second function does nothing when called with an error set. Requires non-null errp, or else the second function can't see the first one fail. This usage has also bled into visitor tests, and two device model object property getters rtc_get_date() and balloon_stats_get_all(). With the "accumulate" technique, you need fewer error checks in callers, and buy that with an error check in every callee. Can be nice. However, mixing the two techniques is confusing. You can't use the "accumulate" technique with functions designed for the "check separately" technique. You can use the "check separately" technique with functions designed for the "accumulate" technique, but then error_set() can't catch you setting an error more than once. Standardize on the "check separately" technique for now, because it's overwhelmingly prevalent.

2014-05-13savevm: Remove all the unneeded version_minimum_id_old (arm)Juan Quintela
After commit 767adce2d, they are redundant. This way we don't assign them except when needed. Once there, there were lots of cases where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (apart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2014-05-13xilinx_timer: Fix writes into TCSR registerGuenter Roeck
The TCSR register has only 11 valid bits. This is now used by the linux kernel to auto-detect endianness, and causes Linux 3.15-rc1 and later to hang when run under qemu-microblaze. Mask valid bits before writing the register to solve the problem. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Reviewed-by: Edgar E. Iglesias <edgar.iglesias@gmail.com> Signed-off-by: Edgar E.

2014-03-27Don't enable a HPET timer if HPET is disabledMatt Lupfer
A HPET timer can be started when HPET is not yet enabled. This will not generate an interrupt to the guest, but causes problems when HPET is later enabled. A timer that is created and expires at least once before HPET is enabled will have an initialized comparator based on a hpet_offset of 0 (uninitialized). When HPET is enabled, hpet_set_timer() is called a second time, which modifies the timer expiry to a time based on the difference between current ticks (measured with the newly initialized hpet_offset) and the timer's comparator (which was generated before hpet_offset was initialized). This results in a long period of no HPET timer ticks. When this occurs with a CentOS 5.x guest, the guest may not receive timer interrupts during its narrow timer check window and panic on boot.

The GPTIMER uses 32-bit registers. Use a 64-bit operation to get the ptimer count, otherwise we end up with a count of 0 for GPTIMER counter values of 0xffffffff. Use the GPTIMER counter value for tracing to avoid an overflow of the 32-bit value passed to trace_grlib_gptimer_enable().
