* agp: switch AGP to use page array instead of unsigned long arrayDave Airlie2009-06-18
| | | | | | | | | This switches AGP to use an array of pages for tracking the pages allocated to the GART. This should enable GEM on PAE to work a lot better as we can pass highmem pages to the PAT code and it will do the right thing with them. Signed-off-by: Dave Airlie <airlied@redhat.com>

* drm/radeon: command stream checker for r3xx-r5xx hardwareJerome Glisse2009-06-18
| | | | | | | | | | | | | | | | | | | | | | For security purpose we want to make sure the userspace process doesn't access memory beyond buffer it owns. To achieve this we need to check states the userspace program. For color buffer and zbuffer we check that the clipping register will discard access beyond buffers set as color or zbuffer. For vertex buffer we check that no vertex fetch will happen beyond buffer end. For texture we check various texture states (number of mipmap level, texture size, texture depth, ...) to compute the amount of memory the texture fetcher might access. The command stream checking impact the performances so far quick benchmark shows an average of 3% decrease in fps of various applications. It can be optimized a bit more by caching result of checking and thus avoid a full recheck if no states changed since last check. Note that this patch is still incomplete on checking side as it doesn't check 2d rendering states. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

* drm/i915: Install fence register for tiled scanout on i915Chris Wilson2009-06-18
| | | | | | | | | | | | With the work by Jesse Barnes to eliminate allocation of fences during execbuffer, it becomes possible to write to the scan-out buffer with it never acquiring a fence (simply by only ever writing to the object using tiled GPU commands and never writing to it via the GTT). So for pre-i965 chipsets which require fenced access for tiled scan-out buffers, we need to obtain a fence register.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch you have following minimal sampling rate restrictions: Kernel restrictions: If CONFIG_NO_HZ is set, the limit is 10ms fixed. If CONFIG_NO_HZ is not set or no_hz=off boot parameter is used, the limits depend on the CONFIG_HZ option: HZ=1000: min=20000us (20ms) HZ=250: min=80000us (80ms) HZ=100: min=200000us (200ms) HW restrictions: Do not sample/poll more often than HW latency * 100 exported by the low level cpufreq HW driver The higher value of above restrictions is the minimal sampling rate that can be set (and can be seen via ondemand/sampling_rate_min sysfs file) Default sampling rate still is HW latency * 1000, but this will now end up in lower values on latest (Intel and AMD) hardware as these can switch really fast and sampling rate mostly was limited to the 80ms or 200ms (depending on whether HZ=250 or HZ=1000 is used).

The patch creates a generic framework that lays on top of bsg and the SGIO v4 ioctl in order to pass transaction requests to LLDD's. The interface supports the following operations: On an fc_host basis: Request login to the specified N_Port_ID, creating an fc_rport. Request logout of the specified N_Port_ID, deleting an fc_rport Send ELS request to specified N_Port_ID w/o requiring a login, and wait for ELS response. Send CT request to specified N_Port_ID and wait for CT response. Login is required, but LLDD is allowed to manage login and decide whether it stays in place after the request is satisfied. Vendor-Unique request. Allows a LLDD-specific request to be passed to the LLDD, and the passing of a response back to the application. On an fc_rport basis: Send ELS request to nport and wait for ELS response. Send CT request to nport and wait for CT response. The patch also exports several headers from include/scsi such that they can be available to user-space applications: include/scsi/scsi.h include/scsi/scsi_netlink.h include/scsi/scsi_netlink_fc.h include/scsi/scsi_bsg_fc.h For further information, refer to the last RFC: http://marc.info/?l=linux-scsi&m=123436574018579&w=2 Note: Documentation is still spotty and will be added later.

ATM, only -EIO errors trigger 1., other errors trigger 2. The idea is that if we know we encountered an I/O error, do 1. Otherwise, we do not know how to react, and do 2., just in case. E.g., if the underlying driver became crazy because of a bug, we do not want to harm any data, and switch to R/O mode. This patch does 2 things: 1. Makes sure reads from the source PEB always cause 1. This is more consistent with other reads which come from the upper layers and never cause R/O. 2. Teaches UBI to do 1. also on -EBADMSG, UBI_IO_BAD_VID_HDR, -ENOMEM, and -ETIMEOUT. But this is only when reading the target PEB. This preblems were hunted by Adrian Hunter.
