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().

* Calculate ram split, for memory below and above 4G. It's a bit
|
|
* complicated for backward compatibility reasons ...
|
|
*
|
|
* - Traditional split is 3.5G (lowmem = 0xe0000000). This is the
|
|
* default value for max_ram_below_4g now.
|
|
*
|
|
* - Then, to gigabyte align the memory, we move the split to 3G
|
|
* (lowmem = 0xc0000000). But only in case we have to split in
|
|
* the first place, i.e. ram_size is larger than (traditional)
|
|
* lowmem. And for new machine types (gigabyte_align = true)
|
|
* only, for live migration compatibility reasons.
|
|
*
|
|
* - Next the max-ram-below-4g option was added, which allowed to
|
|
* reduce lowmem to a smaller value, to allow a larger PCI I/O
|
|
* window below 4G. qemu doesn't enforce gigabyte alignment here,
|
|
* but prints a warning.
|
|
*
|
|
* - Finally max-ram-below-4g got updated to also allow raising lowmem,
|
|
* so legacy non-PAE guests can get as much memory as possible in
|
|
* the 32bit address space below 4G.
|
|
*
|
|
* - Note that Xen has its own ram setp code in xen_ram_init(),
|
|
* called via xen_hvm_init().
|
|
*
|
|
* Examples:
|
|
* qemu -M pc-1.7 -m 4G (old default) -> 3584M low, 512M high
|
|
* qemu -M pc -m 4G (new default) -> 3072M low, 1024M high
|
|
* qemu -M pc,max-ram-below-4g=2G -m 4G -> 2048M low, 2048M high
|
|
* qemu -M pc,max-ram-below-4g=4G -m 3968M -> 3968M low (=4G-128M)

/* In real world different GPU should have different PCH. But actually

* the different PCH DIDs likely map to different PCH SKUs. We do the
|
|
* same thing for the GPU. For PCH, the different SKUs are going to be
|
|
* all the same silicon design and implementation, just different
|
|
* features turn on and off with fuses. The SW interfaces should be
|
|
* consistent across all SKUs in a given family (eg LPT). But just same
|
|
* features may not be supported.
|
|
*
|
|
* Most of these different PCH features probably don't matter to the
|
|
* Gfx driver, but obviously any difference in display port connections
|
|
* will so it should be fine with any PCH in case of passthrough.
|

*
|

* So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell)
|
|
* scenarios, 0x9cc3 for BDW(Broadwell).
