151870cc0b Display enabled CPUs as a scrollable list in the config menu. 
This removes a constraint on the number of CPU cores we can support.

ab278566e4 Bypass start barriers during dummy runs. 
This should speed up the dummy runs on distributed SMP systems.

fe4374e818 Allocate the main program stacks after the loaded program. 
After we relocate the program, we restart it. So there is no need to copy
over the old stack contents. This allows us to increase the maximum number
of APs without a run time overhead. The maximum number of APs will still
be limited by the size of low memory.

09890bf0cd Support more than 32 CPU cores in main display. 
Either one core is active or all enabled cores are active, so we don't
really need a separate spinner for each core.

0fded3e321 Store pmem temporary arrays on the stack to reduce memory footprint. 
Now we have more stack space available for the BSP during initialisation,
we no longer need to store the temporary data off stack.

Martin Whitaker
0aa1b1fa97 Rearrange stack space to reduce memory footprint. 
The BSP only needs extra stack space during program initialisation. The APs
aren't running at that point, so by positioning the BSP stack above the AP
stacks, it can extend down into the AP stack space without causing any
problems.

4400ec6f17 Rename usbkbd to usbhcd to better reflect the new design. 2022-01-08 23:14:50 +00:00
Martin Whitaker
52a87c5d40 Add support for USB hubs. 
This refactors the USB driver code into a more object-oriented design,
with usbkbd.c being the base class and ohci.c and xhci.c being subclasses.
This makes the code that performs USB device enumeration independent of
the host controller.

9785d8f8b9 Map USB controller registers into the reserved area of virtual memory. 
This ensures they are accessible when the test is running, and if they
are physically mapped above 4GB.

ad6c7d0455 Use F10 (or '0'), not ESC to exit menus. 
This avoids accidentally rebooting by pressing the key too many times.

d9fee4dcbb Flush caches between writing and verifying test data. 
Mostly we write and read large chunks of data which will make it likely
that the data is no longer in the cache when we come to verify it. But
this is not always true, and in any case, we shouldn't rely on it.

11c0c6c2f5 Use atomic memory read/write functions in tests. 
This ensures compiler optimisations won't interfere with the tests.

abbee1a25f Use 'size -B' instead of 'size -G' to determine BSS size. 
The -G option is a relatively recent addition, so fails on older
systems (issue #11).
