2017-04-27qemu-img: Document backing optionsMax Reitz
The create and convert subcommands have shorthands to set the backing_file and, in the case of create, the backing_fmt options for the new image. However, they have not been documented so far, which is remedied by this patch.

2017-04-27qemu-img/convert: Move bs_n > 1 && -B check downMax Reitz
It does not make much sense to use a backing image for the target when you concatenate multiple images (because then there is no correspondence between the source images' backing files and the target's); but it was still possible to give one by using -o backing_file=X instead of -B X. Fix this by moving the check. (Also, change the error message because -B is not the only way to specify the backing file, evidently.)

2017-04-27qemu-img/convert: Use @opts for one thing onlyMax Reitz
After storing the creation options for the new image into @opts, we fetch some things for our own information, like the backing file name, or whether to use encryption or preallocation. With the -n parameter, there will not be any creation options; this is not too bad because this just means that querying a NULL @opts will always return the default value. However, we also use @opts for the --object options. Therefore, @opts is not necessarily NULL if -n was specified; instead, it may contain those options. In practice, this probably does not cause any problems because there most likely is no object that supports any of the parameters we query here, but this is neither something we should rely on nor does this variable reuse make the code very nice to read. Therefore, just use a separate variable for the --object options. Signed-off-by: Max Reitz <mreitz@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-04-27block: fix alignment calculations in bdrv_co_do_zero_pwritevDenis V. Lunev
tail_padding_bytes is calculated wrong. F.e. for offset = 0 bytes = 2048 align = 512 we will have tail_padding_bytes = 512 which is definitely wrong. The patch fixes that arithmetics. Fortunately this problem is harmless, we will have 1 extra allocation and free thus there is no need to put this into stable. The problem is here from the very beginning. Signed-off-by: Denis V.

2017-04-27block: Do not unref bs->file on error in BD's openMax Reitz
The block layer takes care of removing the bs->file child if the block driver's bdrv_open()/bdrv_file_open() implementation fails. The block driver therefore does not need to do so, and indeed should not unless it sets bs->file to NULL afterwards -- because if this is not done, the bdrv_unref_child() in bdrv_open_inherit() will dereference the freed memory block at bs->file afterwards, which is not good. We can now decide whether to add a "bs->file = NULL;" after each of the offending bdrv_unref_child() invocations, or just drop them altogether. The latter is simpler, so let's do that.

2017-04-27iotests: 109: Filter out "len" of failed jobsFam Zheng
Mirror calculates job len from current I/O progress: s->common.len = s->common.offset + (cnt + s->sectors_in_flight) * BDRV_SECTOR_SIZE; The final "len" of a failed mirror job in iotests 109 depends on the subtle timing of the completion of read and write issued in the first mirror iteration. The second iteration may or may not have run when the I/O error happens, resulting in non-deterministic output of the BLOCK_JOB_COMPLETED event text. Similar to what was done in a752e4786, filter out the field to make the test robust.

The PIDR (process id register) is used to store the id of the currently running process, which is used to select the process table entry used to perform address translation. This means that when we write to this register all the translations in the TLB become outdated as they are for a previously running process. Thus when this register is written to we need to invalidate the TLB entries to ensure stale entries aren't used to to perform translation for the new process, which would result in at best segfaults or alternatively just random memory being accessed.

2017-04-26ppc/pnv: populate device tree for RTC devicesCédric Le Goater
The code could be common to any ISA device but we are missing the IO length. Signed-off-by: Cédric Le Goater <clg@kaod.org> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2017-04-26ppc/pnv: scan ISA bus to populate device treeCédric Le Goater
This is an empty shell that we will use to include nodes in the device tree for ISA devices. We expect RTC, UART and IPMI BT devices. Signed-off-by: Cédric Le Goater <clg@kaod.org> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2017-04-26ppc/pnv: enable only one LPC busCédric Le Goater
The default LPC bus of a multichip system is on chip 0. It's recognized by the firmware (skiboot) using a "primary" property in the device tree. We introduce a pnv_chip_lpc_offset() routine to locate the LPC node of a chip and set the property directly from the machine level.

2017-04-26ppc/pnv: Add support for POWER8+ LPC ControllerBenjamin Herrenschmidt
It adds the Naples chip which supports proper LPC interrupts via the LPC controller rather than via an external CPLD. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> [clg: - updated for qemu-2.9 - ported on latest PowerNV patchset - moved the IRQ handler in pnv_lpc.c - introduced pnv_lpc_isa_irq_create() to create the ISA IRQs ] Signed-off-by: Cédric Le Goater <clg@kaod.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2017-04-26spapr: remove the 'nr_servers' field from the machineCédric Le Goater
xics_system_init() does not need 'nr_servers' anymore as it is only used to define the 'interrupt-controller' node in the device tree. So let's just compute the value when calling spapr_dt_xics(). This also gives us an opportunity to simplify the xics_system_init() routine and introduce a specific spapr_ics_create() helper to create the sPAPR ICS object.

2017-04-26ipmi: introduce an ipmi_bmc_gen_event() APICédric Le Goater
It will be used to fill the message buffer with custom events expected by some systems. Typically, an Open PowerNV platform guest is notified with an OEM SEL message before a shutdown or a reboot.

2017-04-26ipmi: introduce an ipmi_bmc_sdr_find() APICédric Le Goater
This patch exposes a new IPMI routine to query a sdr entry from the sdr table maintained by the IPMI BMC simulator. The API is very similar to the internal sdr_find_entry() routine and should be used the same way to query one or all sdrs. A typical use would be to loop on the sdrs to build nodes of a device tree.
