2012-01-04vmstate, memory: decouple vmstate from memory APIAvi Kivity1-1/+2
Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-10-06PPC: booke timersFabien Chouteau1-1/+1
While working on the emulation of the freescale p2010 (e500v2) I realized that there's no implementation of booke's timers features. Currently mpc8544 uses ppc_emb (ppc_emb_timers_init) which is close but not exactly like booke (for example booke uses different SPR).

2010-09-24powerpc: Make the decr interrupt type overridableEdgar E. Iglesias1-1/+1
Make it possible for boards to override the kind of interrupt to be signaled when the decr timer hits. The 405's signal PIT interrupts while the 440's signal DECR. Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2010-08-26ppc4xx: don't unregister RAM at resetHollis Blanchard1-1/+0
The PowerPC 4xx SDRAM controller emulation unregisters RAM in its reset callback. However, qemu_system_reset() is now called at initialization time, so all RAM is unregistered before starting the guest (!). Signed-off-by: Hollis Blanchard <hollis@penguinppc.org>
2010-08-26ppc4xx: correct SDRAM controller warning message conditionHollis Blanchard1-1/+1
The message "Truncating memory to %d MiB to fit SDRAM controller limits" should be displayed only when a user chooses an amount of RAM which can't be represented by the PPC 4xx SDRAM controller (e.g. 129MB, which would only be valid if the controller supports a bank size of 1MB).

2010-07-06qemu_ram_alloc: Add DeviceState and name parametersAlex Williamson1-1/+3
These will be used to generate unique id strings for ramblocks. The name field is required, the device pointer is optional as most callers don't have a device. When there's no device or the device isn't a child of a bus implementing BusInfo.get_dev_path, the name should be unique for the platform.

2009-12-21PPC: Make DCR uint32_tAlexander Graf1-7/+7
For what I know DCR is always 32 bits wide, so we should also use uint32_t to pass it along the stacks.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-35/+35
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-06-29Revert "Introduce reset notifier order"Jan Kiszka1-3/+3
This reverts commit 8217606e6edb49591b4a6fd5a0d1229cebe470a9 (and updates later added users of qemu_register_reset), we solved the problem it originally addressed less invasively. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-16Remove io_index argument from cpu_register_io_memory()Avi Kivity1-1/+1
The parameter is always zero except when registering the three internal io regions (ROM, unassigned, notdirty). Remove the parameter to reduce the API's power, thus facilitating future change. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22Introduce reset notifier orderJan Kiszka1-3/+3
Add the parameter 'order' to qemu_register_reset and sort callbacks on registration. On system reset, callbacks with lower order will be invoked before those with higher order. Update all existing users to the standard order 0. Note: At least for x86, the existing users seem to assume that handlers are called in their registration order. Therefore, the patch preserves this property. If someone feels bored, (s)he could try to identify this dependency and express it properly on callback registration.

2008-12-15target-ppc: create a helper function to allow more flexible RAM allocation ↵aurel321-0/+42
for PPC 4xx The 4xx SDRAM controller supports a small number of banks, and each bank must be one of a small set of sizes. The number of banks and the supported sizes varies by SoC. This function uses the user-specified RAM size to fill in the "ram_bases" and "ram_sizes" arrays required by ppc4xx_sdram_init().
