2012-07-09fdc_test: update media_change testPavel Hrdina1-8/+17
After rewrite DSKCHG bit handling the test has to be updated. Now is needed to seek to different track to clear DSKCHG bit. Signed-off-by: Pavel Hrdina <phrdina@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-07-09fdc: fix interrupt handlingPavel Hrdina1-13/+21
If you call the SENSE INTERRUPT STATUS command while there is no interrupt waiting you get as result unknown command. Fixed status0 register handling for read/write/format commands. Signed-off-by: Pavel Hrdina <phrdina@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-07-09fdc: rewrite seek and DSKCHG bit handlingPavel Hrdina1-38/+41
This bit is cleared on every successful seek to a different track (cylinder). The seek is also called on revalidate or on read/write/format commands which also clear the DSKCHG bit. Signed-off-by: Pavel Hrdina <phrdina@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-07-09block: introduce bdrv_swap, implement bdrv_append on top of itPaolo Bonzini2-85/+100
The new function can be made a bit nicer than bdrv_append. It swaps the whole contents, and then swaps back (using the usual t=a;a=b;b=t idiom) the fields that need to stay on top. Thus, it does not need explicit bdrv_detach_dev, bdrv_iostatus_disable, etc. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-07-09block: copy over job and dirty bitmap fields in bdrv_appendPaolo Bonzini1-0/+15
While these should not be in use at the time a transaction is started, a command in the prepare phase of a transaction might have added them, so they need to be brought over. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-07-09blkdebug: optionally tie errors to a specific sectorPaolo Bonzini1-2/+24
This makes blkdebug scripts more powerful, and independent of the exact sequence of operations performed by streaming. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-07-09blkdebug: store list of active rulesPaolo Bonzini1-38/+31
This prepares for the next patch, where some active rules may actually not trigger depending on input to readv/writev. Store the active rules in a SIMPLEQ (so that it can be emptied easily with QSIMPLEQ_INIT), and fetch the errno/once/immediately arguments from there.

2012-07-09blkdebug: pass getlength to underlying filePaolo Bonzini1-0/+6
This is required when using blkdebug with raw format. Unlike qcow2/QED, raw asks blkdebug for the length of the file, it doesn't get it from a header. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-07-09blockdev: warn when copy_on_read=on and readonly=onStefan Hajnoczi1-0/+4
If the image is read-only then it's not possible to copy read data into it. Therefore copy-on-read is automatically disabled for read-only images. Up until now this behavior was silent, add a warning so the user knows why copy-on-read is not working.

2012-07-09qcow2: preserve free_byte_offset when qcow2_alloc_bytes() failsStefan Hajnoczi1-3/+4
When qcow2_alloc_clusters() error handling code was introduced in commit 5d757b563d59142ca81e1073a8e8396750a0ad1a, the value of free_byte_offset was clobbered in the error case. This patch keeps free_byte_offset at 0 so we will try to allocate clusters again next time this function is called.

2012-07-09qcow2: fix #ifdef'd qcow2_check_refcounts() callersStefan Hajnoczi2-4/+4
The DEBUG_ALLOC qcow2.h macro enables additional consistency checks throughout the code. This makes it easier to spot corruptions that are introduced during development. Since consistency check is an expensive operation the DEBUG_ALLOC macro is used to compile checks out in normal builds and qcow2_check_refcounts() calls missed the addition of a new function argument.

2012-07-07target-i386: Remove confusing X86_64_DEF macroPeter Maydell1-15/+24
The X86_64_DEF macro is a confusing way of making some terms in a conditional only appear if TARGET_X86_64 is defined. We only use it in two places, and in both cases this is for making the same test, so abstract that check out into a function where we can use a more conventional #ifdef.

2012-07-07target-i386: Remove unused macrosPeter Maydell1-6/+0
Commit 11f8cdb removed all the uses of the X86_64_ONLY macro. The BUGGY_64() macro has been unused for a long time: it originally marked some ops which couldn't be enabled because of issues with the pre-TCG code generation scheme.

2012-07-05target-i386: Fix compilation with --enable-debugStefan Weil1-25/+34
commit c4baa0503d9623f1ce891f525ccd140c598bc29a improved SSE table type safety which now raises compiler errors when latest QEMU was configured with --enable-debug. Fix this by splitting the SSE tables even further to separate helper functions with different signatures. Instead of crashing by calling address 0, the code now jumps to label illegal_op.

Make the state fields rx_desc_addr and tx_desc_addr uint32_t; this matches the VMStateDescription, and also conforms to how hardware works: the registers don't magically become larger if the device is attached to a CPU with a larger physical address size. It also fixes a compile failure if the target_phys_addr_t type is changed to 64 bits. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Peter A. G.

2012-07-04i.MX31: Clock Control ModulePeter Chubb3-1/+332
For Linux to be able to work out how fast its clocks are going, so that timer ticks come approximately at the right time, it needs to be able to query the clock control module (CCM). This is the start of a CCM implementation. It currently knows only about the MCU, HSP and IPG clocks --- i.e., the ones used to feed the periodic and general purpose timers.
