<p class="MsoNormal">Dear all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please find the attached patch from PMC. Password is pmc123.<o:p></o:p></p>
<p class="MsoNormal">The following tests had been completed on Windows 7, 8, 8.1, Windows Server 2012, 2012 R2.<o:p></o:p></p>
<p class="MsoNormal">- Disk Formats (Quick and Full formats)<o:p></o:p></p>
<p class="MsoNormal">- IOMeter read/write accesses<o:p></o:p></p>
<p class="MsoNormal">- SDStress<o:p></o:p></p>
<p class="MsoNormal">- NVMe SCSI Compliance <o:p></o:p></p>
<p class="MsoNormal">- Install/Uninstall driver<o:p></o:p></p>
<p class="MsoNormal">- Disable/Enable driver<o:p></o:p></p>
<p class="MsoNormal">- All WHQL tests passed with HCK 8.100.26795 on Windows Server 2012 R2, except the following tests exempted via Errata ID 4693:<o:p></o:p></p>
<p class="MsoNormal">1. NVMe Device Capabilities <o:p></o:p></p>
<p class="MsoNormal">2. NVMe Queue Pause-Resume<o:p></o:p></p>
<p class="MsoNormal">3. NVMe Queue Utilization<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The changes of this patch includes two portions: WHQL related changes and Format NVM changes.<o:p></o:p></p>
<p class="MsoNormal">< WHQL related changes ><o:p></o:p></p>
<p class="MsoNormal">1. For "Static Tools Logo test" on server systems, it requires Driver Verification Logs.
<o:p></o:p></p>
<p class="MsoNormal">Most current WDK bundled with VS2013 has a known issue that has a conflict in function
<o:p></o:p></p>
<p class="MsoNormal">prototype definition for StorPortReadRegisterUlong64. Due to the conflict, Code Analysis fails<o:p></o:p></p>
<p class="MsoNormal">and can't generate Code Analysis log. Therefore, we have to fall back to use
<o:p></o:p></p>
<p class="MsoNormal">StorPortReadRegisterUlong for the time being in nvmeInit.c and nvmestd.c<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">2. Added function type declarations in nvmeStd.h in order to pass Static Driver Verifier and
<o:p></o:p></p>
<p class="MsoNormal">generate SDV log.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">3. In order to pass Inquiry command, Device Identification VPD Page (part of NVMe SCSI Compliance test), the driver
<o:p></o:p></p>
<p class="MsoNormal">needs to report SCSI Name String Designation Descriptor (Type 8). For the time being, I added reporting the string
<o:p></o:p></p>
<p class="MsoNormal">as "SCSINVMe". You may change it to whatever strings as you wish. Judy from Samsung is working
<o:p></o:p></p>
<p class="MsoNormal">on definition of the string as well.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">< Format NVM Changes ><o:p></o:p></p>
<p class="MsoNormal">1. Added storportdebugprints in nvmesnti.c.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">2. In nvmestd.c and nvmestd.h :<o:p></o:p></p>
<p class="MsoNormal">- Added NVMeIsReadWritCmd<o:p></o:p></p>
<p class="MsoNormal">- In NVMeBuildIo, block Read/write commands while Format NVM is in progress.<o:p></o:p></p>
<p class="MsoNormal">- Added one parameter of NVMeIsNamespaceVisible to allow specifying the target namespaceID.<o:p></o:p></p>
<p class="MsoNormal">- Added NVMeFormatNVMHotRemoveNamespace and NVMeFormatNVMHotAddNamespace<o:p></o:p></p>
<p class="MsoNormal">- Changed the state machine transitions/processes in NVMeIoctlFormatNVMCallback<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please review/test the patch and provide your feedback at your earliest convenience. Thank you very much.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Regards,<o:p></o:p></p>
