check the return value of the function it calls and error if it's non-0 Fixup qemu_rdma_init_one_block that is the only current caller, and rdma_add_block the only function it calls using it. Pass the name of the ramblock to the function; helps in debugging.

If DMA's owning thread cancels the IO while the bounce buffer's owning thread is notifying the "cpu client list", a use-after-free happens: continue_after_map_failure dma_aio_cancel ------------------------------------------------------------------ aio_bh_new qemu_bh_delete qemu_bh_schedule (use after free) Also, the old code doesn't run the bh in the right AioContext. Fix both problems by passing a QEMUBH to cpu_register_map_client.

The global parameter 'ram_size' does not take into account the hotplugged memory. In some codes, we use 'ram_size' as current VM's real RAM size, which is not correct. Add function 'get_current_ram_size' to calculate VM's current RAM size, it will enumerate present memory devices and also plus ram_size.

由 Alexander Graf 提交于
We use the rom infrastructure to write firmware and/or initial kernel blobs into guest address space. So we're basically emulating the cache off phase on very early system bootup. That phase is usually responsible for clearing the instruction cache for anything it writes into cachable memory, to ensure that after reboot we don't happen to execute stale bits from the instruction cache. So we need to invalidate the icache every time we write a rom into guest address space. We do not need to do this for every DMA since the guest expects it has to flush the icache manually in that case. This fixes random reboot issues on e5500 (booke ppc) for me.

ram_addr_t must be large enough to address any address of the host. For hosts with sizeof(unsigned long) == sizeof(void *), this patch changes nothing. All currently supported hosts fall into this category. For w64 hosts, sizeof(unsigned long) is 4 while sizeof(void *) is 8, so the use of uintptr_t is needed.
