|
|
Changed the accessor to reuse flexpages, with new flexpage creation being |
|
|
When purging flexpages, make sure that the positions are also purged. This was |

Attach accessors when making them available in the paging coordinator, hopefully |
|
|

|
|
Fixed counter usage in the page queue, also handling removal concurrency issues. |
|
|
Moved the pipe accessor implementation into a separate file. |
|
|
Introduced a separate abstraction for the accessor page mapping. |
|
|
When removing flexpages, purge them regardless of the number of users. |
|
|
Moved locking into the PageQueue class. |
|
|
Removed pending flexpages; retain accessor locks until flexpages are queued. |
|
|
Introduced a queue abstraction to simplify the code manipulating the queue. |
|
|
Delete flexpages in their responsible accessors. |
|
|
Avoid duplication of pending flexpage queue entries. |
|
|
Acquire the flexpage mapping lock when removing pending flexpages. |
|
|
Added missing library dependency exposed when linking statically. |
|
|
Added some debugging code showing the flexpage mappings. |
|
|
Differentiate map operation debugging output. |
|
|
Use delete instead of free; added debugging output. |
|
|
Added locking methods; fixed flushing conditions, avoiding inadvertent |
|
|
Use an explicit argument with flush_all. |
|
|
Guard the accessor removal operation with the semaphore. |
|
|
Introduced an atomic operation for establishing an accessor for a file. |
|
|
Provide the data extent when obtaining the next pipe region. |
|
|
Added support for a pipe resource using pager and accessor functionality. |
|
|
Added virtual destructor for Accessor. |
|
|
Permit limitless page collections. |
|
|
Added a clear method and an initial value for _data_start of zero. |
|
|
Added some comments. |
|
|
Removed pipe-related resources pending their replacement. |
|
|
Removed the debugging macro employing pages_for_file. |
|
|
Made various methods protected, removed pages_for_file. |
|
|
Introduced a counter semaphore to make accessors wait for available flexpages. |
|
|
Employed added support for ahead-of-time reply/completion functions to send |
|
|
Bundled pending set modifications with queue modifications. |
|
|
Introduced concurrency control measures to ensure that flexpages are made |
|
|
Added missing semaphore capability allocation. |
|
|
Added missing semaphore guarding of queue insertion. |
|
|
Fixed queue item retrieval to obtain a copy of the item before removal. |
|
|
Introduced critical sections guarding flexpage retrieval and map accesses in |
|
|
Removed superfluous STL comparison "functor". |
|
|
Removed storage of a computed l4_fpage_t value. |
|
|
Attempt to handle various race conditions by guarding removal from the flexpage |
|
|
Consolidated various methods to simplify the control flow. |
|
|
Switched to queuing and storing pointers to flexpages. This does not look as |
|
|
Moved flexpage management for individual files into accessors. This permits |
|
|
Make sure that generated headers are available when compiling. This becomes much |
|
|
Reorganised the paging mechanism, moving various operations into the accessor. |
|
|
Reorganised the paging code into separate sections of functionality. |
