* util/hexdump: Reorder qemu_hexdump() argumentsPhilippe Mathieu-Daudé2020-09-111-2/+2
| | | | | | | | | | | | | | | | | | qemu_hexdump()'s pointer to the buffer and length of the buffer are closely related arguments but are widely separated in the argument list order (also, the format of <stdio.h> function prototypes is usually to have the FILE* argument coming first). Reorder the arguments as "fp, prefix, buf, size" which is more logical.

| | | | | | | | | | | | | | | Most uses of qemu_hexdump() do not take an array of char as input, forcing use of cast. Since we can use this helper to dump any kind of buffer, use a pointer to void argument instead.

* maint: Include bug-reporting info in --help outputEric Blake2017-08-081-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | These days, many programs are including a bug-reporting address, or better yet, a link to the project web site, at the tail of their --help output. However, we were not very consistent at doing so: only qemu-nbd and qemu-qa mentioned anything, with the latter pointing to an individual person instead of the project. Add a new #define that sets up a uniform string, mentioning both bug reporting instructions and overall project details, and which a downstream vendor could tweak if they want bugs to go to a downstream database. Then use it in all of our binaries which have --help output. The canned text intentionally references http:// instead of https:// because our https website currently causes certificate errors in some browsers. That can be tweaked later once we have resolved the web site issued. Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Daniel P.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support target CPUs having a page size which isn't knownn at compile time. To use this, the CPU implementation should: * define TARGET_PAGE_BITS_VARY * not define TARGET_PAGE_BITS * define TARGET_PAGE_BITS_MIN to the smallest value it might possibly want for TARGET_PAGE_BITS * call set_preferred_target_page_bits() in its realize function to indicate the actual preferred target page size for the CPU (and report any error from it) In CONFIG_USER_ONLY, the CPU implementation should continue to define TARGET_PAGE_BITS appropriately for the guest OS page size. Machines which want to take advantage of having the page size something larger than TARGET_PAGE_BITS_MIN must set the MachineClass minimum_page_bits field to a value which they guarantee will be no greater than the preferred page size for any CPU they create. Note that changing the target page size by setting minimum_page_bits is a migration compatibility break for that machine. For debugging purposes, attempts to use TARGET_PAGE_SIZE before it has been finally confirmed will assert.

* | include: Clean up includesPeter Maydell2016-02-231-1/+0Star
|/ | | | | | | | | | | | | | Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. NB: If this commit breaks compilation for your out-of-tree patchseries or fork, then you need to make sure you add #include "qemu/osdep.h" to any new .c files that you have.

| | | | | | | | | | Our use of glib is now pervasive across QEMU. Move the include of glib-compat.h from qemu-common.h to osdep.h so that it is more widely accessible and doesn't get forgotten by accident. (Failure to include it will result in build failure on old versions of glib which is likely to be unnoticed by most developers.)

* Move page_size_init earlierDr. David Alan Gilbert2015-11-101-0/+1
| | | | | | | | | | | | | The HOST_PAGE_ALIGN macros don't work until the page size variables have been set up; later in postcopy I use those macros in the RAM code, and it can be triggered using -object. Fix this by initialising page_size_init() earlier - it's currently initialised inside the accelerators, move it up into vl.c.

* util - add automated ID generation utilityJeff Cody2015-10-161-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Multiple sub-systems in QEMU may find it useful to generate IDs for objects that a user may reference via QMP or HMP. This patch presents a standardized way to do it, so that automatic ID generation follows the same rules. This patch enforces the following rules when generating an ID: 1.) Guarantee no collisions with a user-specified ID 2.) Identify the sub-system the ID belongs to 3.) Guarantee of uniqueness 4.) Spoiling predictability, to avoid creating an assumption of object ordering and parsing (i.e., we don't want users to think they can guess the next ID based on prior behavior). The scheme for this is as follows (no spaces): # subsys D RR Reserved char --| | | | Subsystem String ----| | | Unique number (64-bit) --| | Two-digit random number ---| For example, a generated node-name for the block sub-system may look like this: #block076 The caller of id_generate() is responsible for freeing the generated node name string with g_free().
