2020-02-19ppc/e500: use memdev for RAMIgor Mammedov1-0/+1
memory_region_allocate_system_memory() API is going away, so replace it with memdev allocated MemoryRegion. The later is initialized by generic code, so board only needs to opt in to memdev scheme by providing MachineClass::default_ram_id and using MachineState::ram instead of manually initializing RAM memory region.

2019-08-16Include hw/boards.h a bit lessMarkus Armbruster1-1/+0
hw/boards.h pulls in almost 60 headers. The less we include it into headers, the better. As a first step, drop superfluous inclusions, and downgrade some more to what's actually needed. Gets rid of just one inclusion into a header.

2018-04-27ppc: e500: switch E500 based machines to full machine definitionIgor Mammedov1-17/+30
Convert PPCE500Params to PCCE500MachineClass which it essentially is, and introduce PCCE500MachineState to keep track of E500 specific state instead of adding global variables or extra parameters to functions when we need to keep data beyond machine init (i.e. make it look like typical fully defined machine). It's pretty shallow conversion instead of currently used trivial DEFINE_MACHINE() macro. It adds extra 60LOC of boilerplate code of full machine definition. The patch on top[1] will use PCCE500MachineState to keep track of platform_bus device and add E500Plate specific machine class to use HOTPLUG_HANDLER for explicitly initializing dynamic sysbus devices at the time they are added instead of delaying it to machine done time by platform_bus_init_notify() which is being removed. 1) <1523551221-11612-3-git-send-email-imammedo@redhat.com> Signed-off-by: Igor Mammedov <imammedo@redhat.com> Suggested-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2015-01-07PPC: e500 pci host: Add support for ATMUsAlexander Graf1-0/+2
The e500 PCI controller has configurable windows that allow a guest OS to selectively map parts of the PCI bus space to CPU address space and to selectively map parts of the CPU address space for DMA requests into PCI visible address ranges. So far, we've simply assumed that this mapping is 1:1 and ignored it. However, the PCICSRBAR (CCSR mapped in PCI bus space) always has to live inside the first 32bits of address space. This means if we always treat all mappings as 1:1, this map will collide with our RAM map from the CPU's point of view. So this patch adds proper ATMU support which allows us to keep the PCICSRBAR below 32bits local to the PCI bus and have another, different window to PCI BARs at the upper end of address space. We leverage this on e500plat though, mpc8544ds stays virtually 1:1 like it was before, but now also goes via ATMU. With this patch, I can run guests with lots of RAM and not coincidently access MSI-X mappings while I really want to access RAM. Signed-off-by: Alexander Graf <agraf@suse.de>
2015-01-07PPC: mpc8554ds: Tell user about exceeding RAM limitsAlexander Graf1-0/+6

2015-01-07PPC: e500: Move CCSR definition to paramsAlexander Graf1-0/+3

2013-08-28hw: Clean up bogus default boot orderMarkus Armbruster1-1/+0
We set default boot order "cad" in every single machine definition except "pseries" and "moxiesim", even though very few boards actually care for boot order, and "cad" makes sense for even fewer. Machines that care: * pc and its variants Accept up to three letters 'a', 'b' (undocumented alias for 'a'), 'c', 'd' and 'n'. Reject all others (fatal with -boot). * nseries (n800, n810) Check whether order starts with 'n'. Silently ignored otherwise. * prep, g3beige, mac99 Extract the first character the machine understands (subset of 'a'..'f'). Silently ignored otherwise. * spapr Accept an arbitrary string (vl.c restricts it to contain only 'a'..'p', no duplicates). * sun4[mdc] Use the first character. Silently ignored otherwise. Strip characters these machines ignore from their default boot order. For all other machines, remove the unused default boot order alltogether. Note that my rename of QEMUMachine member boot_order to default_boot_order and QEMUMachineInitArgs member boot_device to boot_order has a welcome side effect: it makes every use of boot orders visible in this patch, for easy review.

2013-01-15Make default boot order machine specificAvik Sil1-0/+1
This patch makes default boot order machine specific instead of set globally. The default boot order can be set per machine in QEMUMachine boot_order. This also allows a machine to receive a NULL boot order when -boot isn't used and take an appropriate action accordingly. This helps machine boots from the devices as set in guest's non-volatile memory location in case no boot order is provided by the user.

2012-10-20create struct for machine initialization argumentsEduardo Habkost1-6/+7
This should help us to: - More easily add or remove machine initialization arguments without having to change every single machine init function; - More easily make mechanical changes involving the machine init functions in the future; - Let machine initialization forward the init arguments to other functions more easily. This change was half-mechanical process: first the struct was added with the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local variable initialization to all functions. Then the compiler helped me locate the local variables that are unused, so they could be removed. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
