* iotests/283: Check that finalize drops backup-topMax Reitz2021-03-082-0/+68
| | | | | | | | | | | | | | | | | | | | | | Without any of HEAD^ or HEAD^^ applied, qemu will most likely crash on the qemu-io invocation, for a variety of immediate reasons. The underlying problem is generally a use-after-free access into backup-top's BlockCopyState. With only HEAD^ applied, qemu-io will run into an EIO (which is not capture by the output, but you can see that the qemu-io invocation will be accepted (i.e., qemu-io will run) in contrast to the reference output, where the node name cannot be found), and qemu will then crash in query-named-block-nodes: bdrv_get_allocated_file_size() detects backup-top to be a filter and passes the request through to its child. However, after bdrv_backup_top_drop(), that child is NULL, so the recursive call crashes. With HEAD^^ applied, this test should pass.

* backup-top: Refuse I/O in inactive stateMax Reitz2021-03-081-0/+10
| | | | | | | | | | | | | | | | | | | When the backup-top node transitions from active to inactive in bdrv_backup_top_drop(), the BlockCopyState is freed and the filtered child is removed, so the node effectively becomes unusable. However, noone told its I/O functions this, so they will happily continue accessing bs->backing and s->bcs. Prevent that by aborting early when s->active is false. (After the preceding patch, the node should be gone after bdrv_backup_top_drop(), so this should largely be a theoretical problem. But still, better to be safe than sorry, and also I think it just makes sense to check s->active in the I/O functions.)

* backup: Remove nodes from job in .clean()Max Reitz2021-03-081-0/+1
| | | | | | | | | | | | | | | | | | | | | The block job holds a reference to the backup-top node (because it is passed as the main job BDS to block_job_create()). Therefore, bdrv_backup_top_drop() cannot delete the backup-top node (replacing it by its child does not affect the job parent, because that has .stay_at_node set). That is a problem, because all of its I/O functions assume the BlockCopyState (s->bcs) to be valid and that it has a filtered child; but after bdrv_backup_top_drop(), neither of those things are true. It does not make sense to add new parents to backup-top after backup_clean(), so we should detach it from the job before bdrv_backup_top_drop(). Because there is no function to do that for a single node, just detach all of the job's nodes -- the job does not do anything past backup_clean() anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the MPS2 boards, the first 32 interrupt lines are entirely internal to the SSE; interrupt lines for devices outside the SSE start at 32. In the application notes that document each FPGA image, the interrupt wiring is documented from the point of view of the CPU, so '0' is the first of the SSE's interrupts and the devices in the FPGA image itself are '32' and up: so the UART 0 Receive interrupt is 32, the SPI #0 interrupt is 51, and so on. Within our implementation, because the external interrupts must be connected to the EXP_IRQ[0...n] lines of the SSE object, we made the get_sse_irq_in() function take an irqno whose values start at 0 for the first FPGA device interrupt. In this numbering scheme the UART 0 Receive interrupt is 0, the SPI #0 interrupt is 19, and so on. The result of these two different numbering schemes has been that half of the devices were wired up to the wrong IRQs: the UART IRQs are wired up correctly, but the DMA and SPI devices were passing start-at-32 values to get_sse_irq_in() and so being mis-connected. Fix the bug by making get_sse_irq_in() take values specified with the same scheme that the hardware manuals use, to avoid confusion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a long time now the UI layer has guaranteed that the console surface is always 32 bits per pixel, RGB. The TCX code already assumes 32bpp, but it still has some checks of is_surface_bgr() in an attempt to support 32bpp BGR. is_surface_bgr() will always return false for the qemu_console_surface(), unless the display device itself has deliberately created an alternate-format surface via a function like qemu_create_displaysurface_from(). Drop the never-used BGR-handling code, and assert that we have a 32-bit surface rather than just doing nothing if it isn't.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The draw_line16_32() function in the omap_lcdc template header includes an ifdef for the case where HOST_WORDS_BIGENDIAN matches TARGET_WORDS_BIGENDIAN. This is trying to optimise for "source bitmap and destination bitmap format match", but it is broken, because in this function the formats don't match: the source is 16-bit colour and the destination is 32-bit colour, so a memcpy() will produce corrupted graphics output. Drop the bogus ifdef. This bug was introduced in commit ea644cf343129, when we dropped support for DEPTH values other than 32 from the template header. The old #if line was #if DEPTH == 16 && defined(HOST_WORDS_BIGENDIAN) == defined(TARGET_WORDS_BIGENDIAN) and this was mistakenly changed to #if defined(HOST_WORDS_BIGENDIAN) == defined(TARGET_WORDS_BIGENDIAN) rather than deleting the #if as now having an always-false condition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Section D6.7 of the ARM ARM states: For the purpose of determining Tag Check Fault handling, unprivileged load and store instructions are treated as if executed at EL0 when executed at either: - EL1, when the Effective value of PSTATE.UAO is 0. - EL2, when both the Effective value of HCR_EL2.{E2H, TGE} is {1, 1} and the Effective value of PSTATE.UAO is 0. ARM has confirmed a defect in the pseudocode function AArch64.TagCheckFault that makes it inconsistent with the above wording. The remedy is to adjust references to PSTATE.EL in that function to instead refer to AArch64.AccessUsesEL(acctype), so that unprivileged instructions use SCTLR_EL1.TCF0 and TFSRE0_EL1. The exception type for synchronous tag check faults remains unchanged. This patch implements the described change by partially reverting commits 50244cc76abc and cc97b0019bb5.

This problem was fixed on arm virt platform in commit f58b39d2d5b ("virtio-mmio: format transport base address in BusClass.get_dev_path") It works perfectly on arm virt platform. but there is still there on xlnx-versal SOC. The main difference between arm virt and xlnx-versal is they use different way to create virtio-mmio qdev. on arm virt, it calls sysbus_create_simple("virtio-mmio", base, pic[irq]); which will call sysbus_mmio_map internally and assign base address to subsys device mmio correctly. but xlnx-versal's implements won't do this. However, xlnx-versal can't switch to sysbus_create_simple() to create virtio-mmio device. It's because xlnx-versal's cpu use VersalVirt.soc.fpd.apu.mr as it's memory. which is subregion of system_memory. sysbus_create_simple will add virtio to system_memory, which can't be accessed by cpu. Besides, xlnx-versal can't add sysbus_mmio_map api call too, because this will add memory region to system_memory, and it can't be added to VersalVirt.soc.fpd.apu.mr again. We can solve this by assign correct base address offset on dev_path. This path was test on aarch64 virt & xlnx-versal platform.
