As result we can replace stringify(MEMORY_foo) with just MEMORY_foo, which makes code a bit cleaner. No AML change introduced by this patch.

This patch fixes ivshmem to store file descriptor of shared memory. It will be used when vhost-user negotiates vhost-user backend.

However, the following g_array_append_vals(table_data, structures->data, structures->len) may resize and relocate table_data->data[]. Therefore, the usage of 'header' afterwards may be illegal.

Tsirkin @ 2016-01-08 15:08 UTC (permalink / raw) To: qemu-devel Cc: Ruiyu Ni, Peter Maydell, Eduardo Habkost, Igor Mammedov, Paolo Bonzini, Laszlo Ersek, Richard Henderson From: Laszlo Ersek <lersek@redhat.com> The ACPI specification (minimally versions 1.0b through 6.0) define the FADT.CENTURY field as: The RTC CMOS RAM index to the century of data value (hundred and thousand year decimals). If this field contains a zero, then the RTC centenary feature is not supported. If this field has a non-zero value, then this field contains an index into RTC RAM space that OSPM can use to program the centenary field. The x86 targets generate ACPI payload, emulate an RTC (CONFIG_MC146818RTC), and that RTC supports the "centenary feature" (see occurrences of RTC_CENTURY in cmos_ioport_write() and cmos_ioport_read() in "hw/timer/mc146818rtc.c".) However, FADT.CENTURY is left at zero currently: [06Ch 0108 1] RTC Century Index : 00 which -- according to analysis done by Ruiyu Ni at Intel -- should cause Linux and Windows 8+ to think the RTC centenary feature is unavailable, and cause Windows 7 to (incorrectly) assume that the offset to use is constant 0x32. (0x32 happens to be the right value on QEMU, but Windows 7 is wrong to assume anything at all). Exposing the right nonzero offset in FADT.CENTURY informs Linux and Windows 8+ about the right capabilities of the hardware, plus it retrofits our FADT to Windows 7's behavior.
