Adding BAR0 for e500 PCI controller PCI Root complex have TYPE-1 configuration header while PCI endpoint have type-0 configuration header. The type-1 configuration header have a BAR (BAR0). In Freescale PCI controller BAR0 is used for mapping pci address space to CCSR address space. This can used for 2 purposes: 1) for MSI interrupt generation 2) Allow CCSR registers access when configured as PCI endpoint, which I am not sure is a use case with QEMU-KVM guest. What I observed is that when guest read the size of BAR0 of host controller configuration header (TYPE1 header) then it always reads it as 0. When looking into the QEMU hw/ppce500_pci.c, I do not find the PCI controller device registering BAR0. I do not find any other controller also doing so may they do not use BAR0. There are two issues when BAR0 is not there (which I can think of): 1) There should be BAR0 emulated for PCI Root complex (TYPE1 header) and when reading the size of BAR0, it should give size as per real h/w. 2) Do we need this BAR0 inbound address translation? When BAR0 is of non-zero size then it will be configured for PCI address space to local address(CCSR) space translation on inbound access. The primary use case is for MSI interrupt generation. The device is configured with an address offsets in PCI address space, which will be translated to MSI interrupt generation MPIC registers. Currently I do not understand the MSI interrupt generation mechanism in QEMU and also IIRC we do not use QEMU MSI interrupt mechanism on e500 guest machines. But this BAR0 will be used when using MSI on e500. I can see one more issue, There are ATMUs emulated in hw/ppce500_pci.c, but i do not see these being used for address translation. So far that works because pci address space and local address space are 1:1 mapped. BAR0 inbound translation + ATMU translation will complete the address translation of inbound traffic.

qom: Drop parameter @errp of object_property_add() & friends The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

Adding BAR0 for e500 PCI controller PCI Root complex have TYPE-1 configuration header while PCI endpoint have type-0 configuration header. The type-1 configuration header have a BAR (BAR0). In Freescale PCI controller BAR0 is used for mapping pci address space to CCSR address space. This can used for 2 purposes: 1) for MSI interrupt generation 2) Allow CCSR registers access when configured as PCI endpoint, which I am not sure is a use case with QEMU-KVM guest. What I observed is that when guest read the size of BAR0 of host controller configuration header (TYPE1 header) then it always reads it as 0. When looking into the QEMU hw/ppce500_pci.c, I do not find the PCI controller device registering BAR0. I do not find any other controller also doing so may they do not use BAR0. There are two issues when BAR0 is not there (which I can think of): 1) There should be BAR0 emulated for PCI Root complex (TYPE1 header) and when reading the size of BAR0, it should give size as per real h/w. 2) Do we need this BAR0 inbound address translation? When BAR0 is of non-zero size then it will be configured for PCI address space to local address(CCSR) space translation on inbound access. The primary use case is for MSI interrupt generation. The device is configured with an address offsets in PCI address space, which will be translated to MSI interrupt generation MPIC registers. Currently I do not understand the MSI interrupt generation mechanism in QEMU and also IIRC we do not use QEMU MSI interrupt mechanism on e500 guest machines. But this BAR0 will be used when using MSI on e500. I can see one more issue, There are ATMUs emulated in hw/ppce500_pci.c, but i do not see these being used for address translation. So far that works because pci address space and local address space are 1:1 mapped. BAR0 inbound translation + ATMU translation will complete the address translation of inbound traffic.

Adding BAR0 for e500 PCI controller PCI Root complex have TYPE-1 configuration header while PCI endpoint have type-0 configuration header. The type-1 configuration header have a BAR (BAR0). In Freescale PCI controller BAR0 is used for mapping pci address space to CCSR address space. This can used for 2 purposes: 1) for MSI interrupt generation 2) Allow CCSR registers access when configured as PCI endpoint, which I am not sure is a use case with QEMU-KVM guest. What I observed is that when guest read the size of BAR0 of host controller configuration header (TYPE1 header) then it always reads it as 0. When looking into the QEMU hw/ppce500_pci.c, I do not find the PCI controller device registering BAR0. I do not find any other controller also doing so may they do not use BAR0. There are two issues when BAR0 is not there (which I can think of): 1) There should be BAR0 emulated for PCI Root complex (TYPE1 header) and when reading the size of BAR0, it should give size as per real h/w. 2) Do we need this BAR0 inbound address translation? When BAR0 is of non-zero size then it will be configured for PCI address space to local address(CCSR) space translation on inbound access. The primary use case is for MSI interrupt generation. The device is configured with an address offsets in PCI address space, which will be translated to MSI interrupt generation MPIC registers. Currently I do not understand the MSI interrupt generation mechanism in QEMU and also IIRC we do not use QEMU MSI interrupt mechanism on e500 guest machines. But this BAR0 will be used when using MSI on e500. I can see one more issue, There are ATMUs emulated in hw/ppce500_pci.c, but i do not see these being used for address translation. So far that works because pci address space and local address space are 1:1 mapped. BAR0 inbound translation + ATMU translation will complete the address translation of inbound traffic.

qom: Drop parameter @errp of object_property_add() & friends The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

hw/core/loader: Let load_elf() populate a field with CPU-specific flags While loading the executable, some platforms (like AVR) need to detect CPU type that executable is built for - and, with this patch, this is enabled by reading the field 'e_flags' of the ELF header of the executable in question. The change expands functionality of the following functions: - load_elf() - load_elf_as() - load_elf_ram() - load_elf_ram_sym() The argument added to these functions is called 'pflags' and is of type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word' being the type of the field 'e_flags', in both 32-bit and 64-bit variants of ELF header). Callers are allowed to pass NULL as that argument, and in such case no lookup to the field 'e_flags' will happen, and no information will be returned, of course.

Adding BAR0 for e500 PCI controller PCI Root complex have TYPE-1 configuration header while PCI endpoint have type-0 configuration header. The type-1 configuration header have a BAR (BAR0). In Freescale PCI controller BAR0 is used for mapping pci address space to CCSR address space. This can used for 2 purposes: 1) for MSI interrupt generation 2) Allow CCSR registers access when configured as PCI endpoint, which I am not sure is a use case with QEMU-KVM guest. What I observed is that when guest read the size of BAR0 of host controller configuration header (TYPE1 header) then it always reads it as 0. When looking into the QEMU hw/ppce500_pci.c, I do not find the PCI controller device registering BAR0. I do not find any other controller also doing so may they do not use BAR0. There are two issues when BAR0 is not there (which I can think of): 1) There should be BAR0 emulated for PCI Root complex (TYPE1 header) and when reading the size of BAR0, it should give size as per real h/w. 2) Do we need this BAR0 inbound address translation? When BAR0 is of non-zero size then it will be configured for PCI address space to local address(CCSR) space translation on inbound access. The primary use case is for MSI interrupt generation. The device is configured with an address offsets in PCI address space, which will be translated to MSI interrupt generation MPIC registers. Currently I do not understand the MSI interrupt generation mechanism in QEMU and also IIRC we do not use QEMU MSI interrupt mechanism on e500 guest machines. But this BAR0 will be used when using MSI on e500. I can see one more issue, There are ATMUs emulated in hw/ppce500_pci.c, but i do not see these being used for address translation. So far that works because pci address space and local address space are 1:1 mapped. BAR0 inbound translation + ATMU translation will complete the address translation of inbound traffic.
