When the mem_size of the segment is bigger than the file_size, and if this space doesn't overlap another segment, it needs to be cleared. This bug is very similar to the one we had for linux-user, 22d113b52f41 ("linux-user: Fix loading of BSS segments"), where .bss section is encoded as an extension of the the data one by setting the segment p_memsz > p_filesz.

In the past s390 used a fixed command line length of 896 bytes. This has changed with the Linux commit 5ecb2da660ab ("s390: support command lines longer than 896 bytes"). There is now a parm area indicating the maximum command line size. This parm area has always been initialized to zero, so with older kernels this field would read zero and we must then assume that only 896 bytes are available.

2022-01-18ppc/pnv: make PECs create and realize PHB4sDaniel Henrique Barboza2-64/+28
This patch changes the design of the PEC device to create and realize PHB4s instead of PecStacks. After all the recent changes, PHB4s now contain all the information needed for their proper functioning, not relying on PecStack in any capacity. All changes are being made in a single patch to avoid renaming parts of the PecState and leaving the code in a strange way. E.g. rename PecClass->num_stacks to num_phbs, which would then read a pnv_pec_num_stacks[] array. To avoid mixing the old and new design more than necessary it's clearer to do these changes in a single step. The name changes made are: - in PnvPhb4PecState: * rename 'num_stacks' to 'num_phbs' * remove the pec->stacks[] array. Current code relies on the pec->stacks[] obj acting as a simple container, without ever accessing pec->stacks[] for any other purpose. Instead of converting this into a pec->phbs[] array, remove it - in PnvPhb4PecClass, rename *num_stacks to *num_phbs; - pnv_pec_num_stacks[] is renamed to pnv_pec_num_phbs[]. The logical changes: - pnv_pec_default_phb_realize(): * init and set the properties of the PnvPHB4 qdev * do not use stack->phb anymore; - pnv_pec_realize(): * use the new default_phb_realize() to init/realize each PHB if running with defaults; - pnv_pec_instance_init(): removed since we're creating the PHBs during pec_realize(); - pnv_phb4_get_stack(): * renamed to pnv_phb4_get_pec() and returns a PnvPhb4PecState*; - pnv_phb4_realize(): use 'phb->pec' instead of 'stack'. This design change shouldn't caused any behavioral change in the runtime of the machine.

2022-01-18ppc/pnv: remove stack pointer from PnvPHB4Daniel Henrique Barboza2-13/+4
This pointer was being used for two reasons: pnv_phb4_update_regions() was using it to access the PHB and phb4_realize() was using it as a way to determine if the PHB was user created. We can determine if the PHB is user created via phb->pec, introduced in the previous patch, and pnv_phb4_update_regions() is no longer using stack->phb. Remove the pointer from the PnvPHB4 device.

2022-01-18ppc/pnv: reduce stack->stack_no usageDaniel Henrique Barboza1-12/+34
'stack->stack_no' represents the order that a stack appears in its PEC. Its primary use is in XSCOM address space calculation in pnv_phb4_xscom_realize() when calculating the memory region offset. This attribute is redundant with phb->phb_id, which is calculated via pnv_phb4_pec_get_phb_id() using stack->stack_no information. It'll also be awkward to assign it when dealing with PECs and PHBs only in a future patch. A new pnv_phb4_get_phb_stack_no() helper is introduced to eliminate most of the stack->stack_no uses we have. The only use left after this patch is during pnv_pec_stk_default_phb_realize() when calculating phb_id, which will also handled in the next patches.

2022-01-18ppc/pnv: move nest_regs_mr to PnvPHB4Daniel Henrique Barboza1-9/+7
We're now able to cleanly move nest_regs_mr to the PnvPHB4 device. One thing of notice here is the need to use a phb->stack->pec pointer because pnv_pec_stk_nest_xscom_write requires a PEC object. Another thing that can be noticed in the use of 'stack->stack_no' that still remains throughout the XSCOM code. After moving all MemoryRegions to the PnvPHB4 object, this illustrates what is the remaining role of the stack: provide a PEC pointer and the 'stack_no' information. If we can provide these in the PnvPHB4 object instead (spoiler: we can, and we will), the PnvPhb4PecStack device will be deprecated and can be removed.

stack->nest_regs_mr wasn't migrated to PnvPHB4 together with phb->nest_regs[] in the previous patch. We were unable to cleanly convert its write MemoryRegionOps, pnv_pec_stk_nest_xscom_write(), to use PnvPHB4 instead of PnvPhb4PecStack due to pnv_pec_stk_update_map() using a stack. Thing is, we're now able to convert pnv_pec_stk_update_map() because of what the did in previous patch. The need for this intermediate step is a good example of the interconnected relationship between stack and phb that we aim to cleanup.

2022-01-18ppc/pnv: move phbbar to PnvPHB4Daniel Henrique Barboza1-9/+10
This MemoryRegion is simple enough to be moved in a single step. A 'stack->phb' pointer had to be introduced in pnv_pec_stk_update_map() because this function isn't ready to be fully converted to use a PnvPHB4 pointer instead. This will be dealt with in the following patches.

2022-01-18ppc/pnv: use PHB4 obj in pnv_pec_stk_pci_xscom_opsDaniel Henrique Barboza1-5/+5
The current relationship between PnvPhb4PecStack and PnvPHB4 objects is overly complex. Recent work done in pnv_phb4.c and pnv_phb4_pec.c shows that the stack obj role in the overall design is more of a placeholder for its 'phb' object, having no atributes that stand on its own. This became clearer after pnv-phb4 user creatable devices were implemented. What remains now are a lot of stack->phb and phb->stack pointers throughout .read and .write callbacks of MemoryRegionOps that are being initialized in phb4_realize() time. stk_realize() is a no-op if the machine is being run with -nodefaults. The first step of trying to decouple the stack and phb relationship is to move the MemoryRegionOps that belongs to PnvPhb4PecStack to PhbPHB4. Unfortunately this can't be done without some preliminary steps to change the usage of 'stack' and replace it with 'phb' in these read/write callbacks. This patch starts this process by using a PnvPHB4 opaque in pnv_pec_stk_pci_xscom_ops instead of PnvPhb4PecStack.

2022-01-18hw/dma: Let dma_buf_read() / dma_buf_write() propagate MemTxResultPhilippe Mathieu-Daudé4-25/+52
Since commit 292e13142d2, dma_buf_rw() returns a MemTxResult type. Do not discard it, return it to the caller. Pass the previously returned value (the QEMUSGList residual size, which was rarely used) as an optional argument. With this new API, SCSIRequest::residual might now be accessed via a pointer. Since the size_t type does not have the same size on 32 and 64-bit host architectures, convert it to a uint64_t, which is big enough to hold the residual size, and the type is constant on both 32/64-bit hosts. Update the few dma_buf_read() / dma_buf_write() callers to the new API.

2022-01-14block: drop BLK_PERM_GRAPH_MODVladimir Sementsov-Ogievskiy1-2/+1
First, this permission never protected a node from being changed, as generic child-replacing functions don't check it. Second, it's a strange thing: it presents a permission of parent node to change its child. But generally, children are replaced by different mechanisms, like jobs or qmp commands, not by nodes. Graph-mod permission is hard to understand. All other permissions describe operations which done by parent node on its child: read, write, resize. Graph modification operations are something completely different. The only place where BLK_PERM_GRAPH_MOD is used as "perm" (not shared perm) is mirror_start_job, for s->target. Still modern code should use bdrv_freeze_backing_chain() to protect from graph modification, if we don't do it somewhere it may be considered as a bug. So, it's a bit risky to drop GRAPH_MOD, and analyzing of possible loss of protection is hard. But one day we should do it, let's do it now. One more bit of information is that locking the corresponding byte in file-posix doesn't make sense at all.

2022-01-13edid: Added support for 4k@60 Hz monitorSatyeshwar Singh1-0/+3
Previously, the large modes (>1080p) that were generated by Qemu in its EDID were all 50 Hz. If we provide them to a Guest OS and the user selects one of these modes, then the OS by default only gets 50 FPS. This is especially true for Windows OS. With this patch, we are now exposing a 3840x2160@60 Hz which will allow the guest OS to get 60 FPS.

2022-01-13edid: set default resolution to 1280x800 (WXGA)Daniel P. Berrangé1-2/+2
Currently QEMU defaults to a resolution of 1024x768 when exposing EDID info to the guest OS. The EDID default info is important as this will influence what resolution many guest OS will configure the screen with on boot. It can also potentially influence what resolution the firmware will configure the screen with, though until very recently EDK2 would not handle EDID info. One important thing to bear in mind is that the default graphics card driver provided by Windows will leave the display set to whatever resolution was enabled by the firmware on boot. Even if sufficient VRAM is available, the resolution can't be changed without installing new drivers. IOW, the default resolution choice is quite important for usability of Windows. Modern real world monitor hardware for desktop/laptop has supported resolutions higher than 1024x768 for a long time now, perhaps as long as 15+ years. There are quite a wide variety of native resolutions in use today, however, and in wide screen form factors the height may not be all that tall. None the less, it is considered that there is scope for making the QEMU default resolution slightly larger. In considering what possible new default could be suitable, choices considered were 1280x720 (720p), 1280x800 (WXGA) and 1280x1024 (SXGA). In many ways, vertical space is the most important, and so 720p was discarded due to loosing vertical space, despite being 25% wider. The SXGA resolution would be good, but when taking into account window titlebars/toolbars and window manager desktop UI, this might be a little too tall for some users to fit the guest on their physical montior. This patch thus suggests a modest change to 1280x800 (WXGA). This only consumes 1 MB per colour channel, allowing double buffered framebuffer in 8 MB of VRAM. Width wise this is 25% larger than QEMU's current default, but height wise this only adds 5%, so the difference isn't massive on the QEMU side. Overall there doesn't appear to be a compelling reason to stick with 1024x768 resolution. Signed-off-by: Daniel P.
