      tests/ide-test: Create a single unit-test covering more PRDT cases · 59805ae9
      由 Alexander Popov 提交于 
      Fuzzing the Linux kernel with syzkaller allowed to find how to crash qemu
using a special SCSI_IOCTL_SEND_COMMAND. It hits the assertion in
ide_dma_cb() introduced in the commit a718978e in July 2015.
Currently this bug is not reproduced by the unit tests.

Let's improve the ide-test to cover more PRDT cases including one
that causes this particular qemu crash.

The test is developed according to the Programming Interface for
Bus Master IDE Controller (Revision 1.0 5/16/94).

      ide: Fix incorrect handling of some PRDTs in ide_dma_cb() · ed78352a
      由 Alexander Popov 提交于 
      The commit a718978e from July 2015 introduced the assertion which
implies that the size of successful DMA transfers handled in ide_dma_cb()
should be multiple of 512 (the size of a sector). But guest systems can
initiate DMA transfers that don't fit this requirement.

For fixing that let's check the number of bytes prepared for the transfer
by the prepare_buf() handler. The code in ide_dma_cb() must behave
according to the Programming Interface for Bus Master IDE Controller
(Revision 1.0 5/16/94):
1. If PRDs specified a smaller size than the IDE transfer
   size, then the Interrupt and Active bits in the Controller
   status register are not set (Error Condition).
2. If the size of the physical memory regions was equal to
   the IDE device transfer size, the Interrupt bit in the
   Controller status register is set to 1, Active bit is set to 0.
3. If PRDs specified a larger size than the IDE transfer size,
   the Interrupt and Active bits in the Controller status register
   are both set to 1.

      target/hppa: Allow, but diagnose, LDCW aligned only mod 4 · b1af755c
      由 Richard Henderson 提交于 
      The PA-RISC 1.1 specification says that LDCW must be aligned mod 16
or the operation is undefined.  However, real hardware only generates
an unaligned access trap for unaligned mod 4.

Match real hardware, but diagnose with GUEST_ERROR a violation of
the specification.

At the same time fix a bug in the initialization of mop, where the
size was specified twice, and another to free the zero temporary.

      hw/hppa/machine: Map the PDC memory region with higher priority · 4debfdac
      由 Philippe Mathieu-Daudé 提交于 
      The region in range [0xf0000000 - 0xf1000000] is the PDC area
(Processor Dependent Code), where the firmware is loaded.
This region has higher priority than the main memory.

When the machine has more than 3840MB of RAM, there is an
overlap. Since the PDC is closer to the CPU in the bus
hierarchy, it gets accessed first, and the CPU does not have
access to the RAM in this range.

To model the same behavior and keep a simple memory layout,
reduce the priority of the RAM region. The PDC region ends
overlapping the RAM.

      hw/hppa/machine: Restrict the total memory size to 3GB · b7746b11
      由 Philippe Mathieu-Daudé 提交于 
      The hardware expects DIMM slots of 1 or 2 GB, allowing up to
4 GB of memory. We want to accept the same amount of memory the
hardware can deal with. DIMMs of 768MB are not available.

However we have to deal with a firmware limitation: currently
SeaBIOS only supports 32-bit, and expects the RAM size in a
32-bit register. When using a 4GB configuration, the 32-bit
register get truncated and we report a size of 0MB to SeaBIOS,
which ends halting the machine:

  $ qemu-system-hppa -m 4g -serial stdio

  SeaBIOS: Machine configured with too little memory (0 MB), minimum is 16 MB.

  SeaBIOS wants SYSTEM HALT.

The easiest way is to restrict the machine to 3GB of memory.

      This adds emulation of Artist graphics good enough to get a text
console on both Linux and HP-UX. The X11 server from HP-UX also works.

Adjust boot-serial-test to disable graphics, so that SeaBIOS outputs
to the serial port, as expected by the test.
