2020-11-10hw/arm/nseries: Remove invalid/unnecessary n8x0_uart_setup()Philippe Mathieu-Daudé1-11/+0
omap2420_mpu_init() introduced in commit 827df9f3c5f ("Add basic OMAP2 chip support") takes care of creating the 3 UARTs. Then commit 58a26b477e9 ("Emulate a serial bluetooth HCI with H4+ extensions and attach to n8x0's UART") added n8x0_uart_setup() which create the UART and connects it to an IRQ output, overwritting the existing peripheral and its IRQ connection. This is incorrect. Fortunately we don't need to fix this, because commit 6da68df7f9b ("hw/arm/nseries: Replace the bluetooth chardev with a "null" chardev") removed the use of this peripheral. We can simply remove the code.

2020-11-09block: make bdrv_drop_intermediate() less wrongVladimir Sementsov-Ogievskiy1-30/+24
First, permission update loop tries to do iterations transactionally, but the whole update is not transactional: nobody roll-back successful loop iterations when some iteration fails. Second, in the iteration we have nested permission update: c->klass->update_filename may point to bdrv_child_cb_update_filename() which calls bdrv_backing_update_filename(), which may do node reopen to RW. Permission update system is not prepared to nested updates, at least it has intermediate permission-update state stored in BdrvChild structures: has_backup_perm, backup_perm and backup_shared_perm. So, let's first do bdrv_replace_node_common() (which is more transactional than open-coded update in bdrv_drop_intermediate()) and then call update_filename() in separate. We still do not rollback changes in case of update_filename() failure but it's not much worse than pre-patch behavior. Note that bdrv_replace_node_common() does check for frozen children, so corresponding check is dropped in bdrv_drop_intermediate().

Add new parameter to bdrv_replace_node(): auto_skip. With auto_skip=false we'll have stricter behavior: update _all_ from parents or fail. New behaviour will be used in the following commit in block.c, so keep original function name as public interface. Note: new error message is a bit funny in contrast with further "Cannot" in case of frozen child, but we'd better keep some difference to make it possible to distinguish one from another on failure. Still, actually we'd better refactor should_update_child() call to distinguish also different kinds of "should not". Let's do it later.

2020-11-09qcow2: Document and enforce the QCowL2Meta invariantsAlberto Garcia3-14/+29
The QCowL2Meta structure is used to store information about a part of a write request that touches clusters that need changes in their L2 entries. This happens with newly-allocated clusters or subclusters. This structure has changed a bit since it was first created and its current documentation is not quite up-to-date. A write request can span a region consisting of a combination of clusters of different types, and qcow2_alloc_host_offset() can repeatedly call handle_copied() and handle_alloc() to add more clusters to the mix as long as they all are contiguous on the image file. Because of this a write request has a list of QCowL2Meta structures, one for each part of the request that needs changes in the L2 metadata. Each one of them spans nb_clusters and has two copy-on-write regions located immediately before and after the middle region touched by that part of the write request. Even when those regions themselves are empty their offsets must be correct because they are used to know the location of the middle region. This was not always the case but it is not a problem anymore because the only two places where QCowL2Meta structures are created (calculate_l2_meta() and qcow2_co_truncate()) ensure that the copy-on-write regions are correctly defined, and so do assertions like the ones in perform_cow(). The conditional initialization of the 'written_to' variable is therefore unnecessary and is removed by this patch.

2020-11-09block: Remove unused BlockDeviceMapEntryMarkus Armbruster1-29/+0
BlockDeviceMapEntry has never been used. It was added in commit facd6e2 "so that it is published through the introspection mechanism." What exactly introspecting types that aren't used for anything could accomplish isn't clear. What "introspection mechanism" to use is also nebulous. To the best of my knowledge, there has never been one that covered this type. Certainly not query-qmp-schema, which includes only types that are actually used in QMP. Not being able to introspect BlockDeviceMapEntry hasn't bothered anyone enough to complain in almost four years. Get rid of it.

2020-11-09qapi/block-core: Improve MapEntry documentationMax Reitz1-5/+13
MapEntry and BlockDeviceMapEntry are kind of the same thing, and the latter is not used, so we want to remove it. However, the documentation it provides for some fields is better than that of MapEntry, so steal some of it for the latter. (And adjust them a bit in the process, because I feel like we can make them even clearer.)

The nanoMIPS ISA has been announced in 2018 for various projects: GCC: https://gcc.gnu.org/legacy-ml/gcc/2018-05/msg00012.html Linux: https://lwn.net/Articles/753605/ QEMU: https://www.mail-archive.com/qemu-devel@nongnu.org/msg530721.html Unfortunately the links referenced doesn't work anymore (www.mips.com). From this Wayback machine link [1] we can get to a working place to download a toolchain (a more recent release than the one referenced in the announcement mails): http://codescape.mips.com/components/toolchain/nanomips/2018.04-02/downloads.html The toolchain page mention LLVM but simply links http://llvm.org/ where there is no reference on nanoMIPS. The only reference in the GCC mailing list, is the nanoMIPS announcement: https://gcc.gnu.org/pipermail/gcc/2018-May.txt The developer who authored the announcements have been emailed [2] to ask for more information but all their emails are now bouncing: - Your message to Stefan.Markovic@mips.com couldn't be delivered. - Your message to smarkovic@wavecomp.com couldn't be delivered. - Couldn't deliver the message to the following recipients: Robert.Suchanek@mips.com, matthew.fortune@mips.com, marcin.nowakowski@mips.com Our deprecation policy do not allow feature removal before 2 release, therefore declare the nanoMIPS ISA code deprecated as of QEMU 5.2. This gives time to developers to update the QEMU community, or interested parties to step in to maintain this code.
